Event Comment: The United Company. The date of the first performance is stated in Luttrell, A Brief Relation, II, 435, 28 April 1692: On Monday will be acted a new opera, call the Fairy Queen: exceeds former playes: the clothes, scenes, and musick cost 3000#. [According to Some Select Songs As they are Sung in the Fairy Queen (1692) tne singers were Mrs Ayliff, Mrs Dyer, Freeman, Mrs Butler, and Pate. See Purcell's Works, Purcell Society, XII (1903), ii; E. W. White, Early Performances of Purcell's Operas, Theatre Notebook, XIII (1958-59 ), 45; and R. E. Moore, Henry Purcell and the Restoration Theatre, Chapter IV.] Downes, Roscius Anglicanus, pp. 42-43: The Fairy Queen, made into an Opera, from a Comedy of Mr Shakespeare s: This in Ornaments was Superior to the other Two [King Arthur and The Prophetess]; especially in Cloaths, for all the Singers and Dancers, Scenes, Machines and Decorations, all most profusely set off; and excellently perform'd, chiedly the Instrumental and Vocal part Compos'd by the said Mr Purcel, and Dances by Mr Priest. The Court and Town were wonderfully satisfy'd with it; but the Expences in setting it out being so great, the Company got very little by it. Gentleman's Journal, May 1692: The Opera of which I have spoke to you in my former hath at last appear'd, and continues to be represented daily: it is call'd, The Fairy Queen. The Drama is originally Shakespears, the Music and Decorations are extraordinary. I have heard the Dances commended, and without doubt the whole is very entertaining. [As the May issue of the Gentleman's Journal was licensed on 14 May, the statement that The Fairy Queen continued to be acted daily may indicate consecutive performances from 2 May to at le ast 14 May 1692.

Event Comment: The United Company. The date of the first performance is not precisely known, but it was certainly before 17 June 1692, as the Gentleman's Journal, June 1692 (licensed 17 June) states: Regulus, with the Factions of Carthage, by Mr Crown, was acted the last week; that Tragedy is intermixed with a vein of Comedy. You have seen his Works in both. Terence tells us, Dubiam fortunam esse scenicam; and if that great Author had occasi on to complain, those of our Age may well comfort themselves if the Town deceives their expectation. A song, Ah me! to many deaths decreed, the music by Henry Purcell, and set by Mrs Ayliff, is in Purcell's Works, Purcell Society, XXI (1917), vii. But see 24 Aug. 1692

Event Comment: The United Company. As 9 Nov. 1692 is known to be the second day, it is assumed that 8 Nov. 1692 represents the first performance. (See entry for 9 Nov. 1692.) The authorship is uncertain; William Mountfort signed tne Dedication, but its authorship is linked with that of Edward III (November 1690), which may have been by Bancroft. Gentleman's Journal, October 1692 (not issued until November): Henry the Second, King of England, A new Play, by the Author of that call'd Edward the Third, which gave such universal satisfaction, hath been acted several times with applause. It is a Tragedy with a mixture of Comedy....Had you seen it acted, you would own that an Evening is pass'd very agreeably, when at a Representation of that pleasing Piece. [Alfred Harbage, Elizabethan-Restoration Palimpsest, Modern Language Review, XXXV (1940), 312-18, argues that this play is the Elizabethan Henry II once in the possession of Moseley. A song, In vain 'gainst Love I strove, composed by Henry Purcell and sung by Mrs Dyer, not in the printed play, is in Comes Amoris, 1693, and Joyful Cuckoldom 1695. See Purcell's Works, Purcell Society, XX (1916), vii

Event Comment: Gentleman's Journal, November 16@2: In my first Journal I gave you a large account of the Musick Feast on St Cecilia's day; So, to avoid repetitions, I shall onely tell you that the last was no ways inferiour to the former....The following Ode was admirably set to Music by Mr Henry Purcell and perform'd twice with universal applause, particularly the second Stanza, which was sung with incredible Graces by Mr Purcell himself. [See Purcell's Works, Purcell Society, VIII, and Orpheus Britannicus, 1702, 1706, 1711. The Ode appears to have been written by Nicholas Brady.

Event Comment: The United Company. Constatijn Huygens, 16 Jan. 1692@2 O. S. [translation]: In the afternoon I went with Preswitz to the comedy, by Covent Garden, where there was a play about Henry II, but I could not very well understand the comedians, neither what they said. Mrs Barry played the King's wife and Mrs Bracegirdle his mistress, who let the King be poisoned in her presence. Sayer came and sat with us. The best places were for the English crown (Journaal van Constantijn Huygens, Publication of the Dutch Historical Society, New Series, XXV [Utrecht, 1877], 168)

Event Comment: The United Company. The date of the first performance is not known, but it had been acted by the time the January 1692@3 issue of the Gentleman's Journal appeared in March (on page 1 of that issue, the editor states that We are now in March): Mr Southerne's New Comedy, call'd, The Maid's last Prayer, or Any rather than fail, was acted the 3d time this evening, and is to be acted again to morrow. It discovers much knowledge of the Town in its Author; and its Wit and purity of Diction are particularly commended (p. 28). The first song in the play, Tho you make no return to my passion, composed by Henry Purcell, was sung, according to the printed play, by Mrs Hodgson; by Mrs Dyer, according to Thesaurus Musicus, First Book, 1693. The second song, composed by Samuel? Akeroyd, was sung by Mrs Ayliff (Thesaurus Musicus, The First Book, 1693). Another song, No, no, no, no, resistance is but vain, written by Anthony Henley, composed by Henry Purcell, and sung by Mrs Ayliff and Mrs Hodgson, Act IV, is in Purcell's Works, Purcell Society, XX (1916), xiv-xv. A song, Tell me no more I am deceiv'd, written by William Congreve, set by Henry Purcell, and sung by Mrs Ayliff, is in Works, XX (1916), xv-xvi. According to the London Gazette, No. 2852, 9-13 March 1692@3, the play was published "this day" (13 March 1692@3)

Event Comment: The United Company. This performance is on the L. C. list, 5@151, p. 369: ye Q a Box & a Box for ye Maids Honr Fairy Queen. [See also Nicoll, Restoration Drama, p. 352. This play was reprinted in 1693: With Alterations, Additions, and several new Songs. See Purcell's Works, Purcell Society, XII (1903), i.

Event Comment: The United Company. The date of the first performance is not known. The January issue of the Gentleman's Journal, wnich did not appear until some time in February, stated: Mr Congreve...hath written a Comedy, which will be acted in a little time, and is to be call'd, The Old Batchelor (p. 28). The Gentleman's Journal, February 1692@3 (issued in March 1693): The success of Mr Congreve's Old Batchelor has been so extraordinary, that I can tell you nothing new of that Comedy; you have doubtless read it before this, since it has been already printed thrice. And indeed the Wit which is diffus'd through it, makes it lose but few of those Charms in the Perusal, which yield such pleasure in the Representation. Mr Congreve will in some time give us another play; you may judge by this how acceptable it will be (p. 61). In addition, a reference in the Epilogue indicates that it was produced during Lent, ano since the third edition was advertized in the London Gazette, No. 2856, 23-27 March 1693, early March seems the most likely date for the premiere. According to The Female Wits (ca. 1696), The Old Batchelor was acted fourteen days successively. John Barnard of Yale University states that Narcissus Luttrell's copy of The Old Batchelor in the Newberry Library bears the notation: "10d Mar. 16 1692@3." BM Add. Mss. 4221 (341) Memoirs Relating to Mr Congreve Written by Mr Thomas Southern (in Macdonald, Bibliography of Dryden, p. 54n): When he began his Play the Old Batchelor haveing little Acquaintance with the traders in that way, his Cozens recommended him to a friend of theirs, who was very usefull to him in the whole course of his play, he engag'd Mr Dryden in its favour, who upon reading it sayd he never saw such a first play in his life, but the Author not being acquainted with the stage or the town, it woud be pity to have it miscarry for want of a little Assistance: the stuff was rich indeed, it wanted only the fashionable cutt of the town. To help that Mr Dryden, Mr Arthur Manwayring, and Mr Southern red it with great care, and Mr Dryden putt it in the order it was playd, Mr Southerne obtained of Mr Thos. Davenant who then governd the Playhouse, that Mr Congreve should have the privilege of the Playhouse half a year before his play was playd, wh. I never knew allowd any one before. The music for the play was composed by Henry Purcell. See Purcell's Works, Purcell Society, XXI (1917), iii-v

Event Comment: The United Company. This play was apparently revived late in 1693, for a song, There's not a swain on the plain, not printed in the play, the words by N. Henley, sung by Mrs Hudson, is printed in the Gentleman's Journal, January-February 1694 (announced in the London Gazette, 8 March 1693@4). It is also in Joyful Cuckoldom, ca. 1695. See also Purcell's Works, Purcell Society, XXI (1917), xii

Event Comment: The United Company. The date of the first performance is not precisely known, but it seems likely to have been in mid-January. See the discussion under 10 Jan. 1693@4 and Evelyn's remarks on 11 Jan. 1693@4. Part of the music for the play was composed by John Eccles: Young I am and yet unskill'd, sung by a girl, in Gentleman's Journal, January@February 1693@4, and Thesaurus Musicus, 1694: What state of life can be so blest, -Mrs Hudson, in Thesaurus Musicus, 1694. One song was set by Henry Purcell, How happy's the husband, the words by Congreve and sung by Mrs Ayliff, in Thesaurus Musicus, 1694: see also Purcell's Works, Purcell Society, XX (1916), xiii-xiv

Event Comment: The United Company. The date of the premiere is not certain, but the fact that a song in the play, composed by Henry Purcell and sung by Mrs Hudson, is in the Gentleman's Journal, January@February 1693@4 (advertised in the London Gazette, No 2955, 5-8 Marcn 1693@4) suggests that the play had its premiere in February. The play was advertised in the London Gazette, No 2959, 19-22 March 1693@4. The music for additional songs was composed by Henry Purcell: The danger is over, sung by Mrs Hudson, is in Joyful Cuckoldom, ca. 1695; I sighed and owned my love, sung by Mrs Ayliff, is in Thesaurus Musicus, Book III, 1695. See also Purcell's Works, Purcell Society, XX (1916), i-iii. Two songs were composed by John Eccles: Still, I'm grieving, sung by Mrs Bracegirdle; and Give then royal maid your sorrows o're, sung by Mrs Cibber, are in Thesaurus Musicus, 1695. Gentleman's Journal, March 1694 (advertised in London Gazette, No 2964,5-9 April 1694): Mr Southern's new Play call'd The Fatal Marriage; or, The Innocent Adultery, has been so kindly receiv'd, that you are by this time no stranger to its merit. As the world has done it justice, and it is above my praise, I need not expatiate on that subject. [See also 22 March 1693@4.

Event Comment: The United Company. The date of the first performance is not known, but according to the Gentleman's Journal, May 1694, it followed Have at All: the other call'd The married Beau, or the Curious Impertinent, by Mr Crown, already acted many times (p. 134). The manuscript of a song composed by John Eccles and sung by Doggett is in Bodleian, School of Music Collection, c. 95, f 102. One by Henry Purcell, See, where repenting Celia lyes, sung by Mrs Ayliff, is in Thesaurus Musicus, 1695. See also Purcell's Works, Purcell Society, XX (1916), xvii-xviii

Event Comment: The Queen's Birthday Ode, Come, Ye Sons of Art, the music by Henry Purcell, the author of the words not known; and Strike the Viol, sung by Alexander? Damascene, are in Gentleman's Journal, May 1694. See also Purcell's Works, Purcell Society, XXIV (1926), ii

Event Comment: The United Company. The date of the first performance is not known, but a notice in the Gentleman's Journal, October@November 1694, suggests that it was pro6ably acted in September or October: I have only jusy room to tell you, that we have had a new Comedy by Mr Ravenscroft, 'tis call'd, The Canterbury Jests, or a Bargain Broken (p. 276). Tne play was advertised in the London Gazette, No 3037, 17-20 Dec. 1694. A song, Good neighbor, why do you look away, set by Henry Purcell, is in Thesaurus Musicus, 1695. See also Purcell's Works, Purcell Society, XVI (1906), xiii-xv

Event Comment: Christopher Rich's Company. The date of this revival is not certain. Apparently the revival was in preparation before the division of the company, but the publication of the Songs in 1695 confines the production to the period between mid-April and the late autumn. For the opera, see The Works of John Dryden, Vol. VIII: The Plays, edited by John Harrington Smith and Dougald MacMillan (Berkeley and Los Angeles, 1692), pp. 325-30; Moore, Henry Purcell and the Restoration Theatre, Chapter VI;and Purcell's Works, Purcell Society, Vol. XIX. The Songs (1695), the music by Henry Purcell, lists the following pieces and singers: I, Wake, wake, Quivera, sung by Freeman. I, Why shou'd men quarrel, sung by The Boy, with Flutes. Their looks are such that mercy flows, sung by Freeman. II, I come to sing, sung by Freeman. Scorn'd Envy here's nothing, sung by Freeman. Begone, curst Feinds of Hell, sung by Freeman. III, Ah, how happy we are, sung by Freeman and Church. I attempt from Love's sickness to fly, sung by Mrs Cross. IV, They tell us that you mighty powers above, sung by Mrs Cross. In addition, other parts of the opera appeared elsewhere: Act V, a Masque, set by Daniel Purcell, O Bless the Genial Bed with chast delights, in Deliciae Musicae, First Book of the Second Volume, 1696. [The others, since they do not name the performers, are omitted here.

Event Comment: Rich's Company. The date of the first production is not known, but the fact that it was advertised in the London Gazette, No. 3122, 10-14 Oct. 1695, indicates that it was probably acted not later than September 1695. Three songs were published separately: O how you protest, possibly set by Henry Purcell and sung by Mrs Knight; 'Twas within a Furlong, the words by Thomas D'Urfey, set by Henry Purcell, and sung by the Girl [Miss Cross]; and Man is for the woman made, the words by Pierre Motteux and set by Henry Purcell, are in Deliciae Musicae, The Third Book, 1696. See also Purcell's Works, Purcell Society, XX (1916), xix-xx. Preface, Edition of 1696: Notwithstanding the many Accidents that concurr'd to the Ruin of this Play, it succeeded above my Expectations: And I must own my self infinitely oblig'd to the Town, in receiving so favourably, what I at first never design'd for the Stage. Gildon, English Dramatick Poets, p. 121: This particular Play met with pretty good Success, for the Season of the Year, considering it the first Essay by a Young Writer, unacquainted with the Town. A Comparison Between the Two Stages (1702), p. 18: Sullen: Mock-Marriage, a young Fellows of the Town, a Retainer, and kind of Pensioner to the Stage. Ramble: What was it's Fate? Sullen: Damn'd, Damn'd

Event Comment: Rich's Company. The date of the first performance is not known, but the Prologue to Bonduca refers to She Ventures and He Wins. As Bonduca was advertised in the London Gazette, No. 3126, 24-28 Oct. 1695, the play was certainly not acted later than early October 1695, probably not later than September 1695. The Edition of 1696 includes on the titlepage: With A New Entertainment of Musick, Vocal and Instrumental. [The music was composed by Henry Purcell. See Purcell's Works, Purcell Society, XVI, vii-xiii.] Those songs for which a performer is named are as follows: O lead me to some peaceful gloom, sung by Miss Cross, and Sing ye Druids, all your voices raise, sung by Mrs Ayliff, both in Songs in the Tragedy of Bonduca, ca. 1696. To arms, sung by Freeman and Edwards, is in Thesaurus Musicus, The Fifth Book, 1696

Event Comment: Rich's Company. The date of the premiere is not known, but the fact that the play was advertised in the London Gazette, No. 3130, 7-11 Nov. 1695, suggests that it was acted not later than October 1695, although the first production may have been earlier than that. Part of the music was composed by Henry Purcell: Celia has a thousand charms, sung by Young Bowen; Take not a woman's anger ill, sung by Leveridge; and How happy is she, sung by Miss Cross; all are in Deliciae Musicae, The Third Book, 1696. See also Purcell's Works, Purcell Society, XXI (1917), x-xi. Another song, To me you made a thousand vows, set by John Blow, is in Amphion Anglicus, 1700. Dedication, Edition of 1696: I...found so much interrutpion and discouragement from some prejudic'd Gentlemen, who ought to have us'd me better, or, at least, had no reason to use me ill, that I repented I had bestow'd any time upon it....In spite of 'em, my Lord, it was kindly receiv'd, and that too, at a time when the Town was never thinner of Nobility and Gentry

Event Comment: Rich's Company. The date of the first performance is not known, but the fact that the play was advertised in the London Gazette, No. 3140, 12-16 Dec. 1695, to be published 17 Dec. 1695, suggests that its first appearance was not later than November 1695. According to the Edition of 1695, the music was set by the late Henry Purcell, Courteville, Samuel? Aykerod, and other composers. For Purcell's music, see Purcell's Works, Purcell Society, XVI (1906), xxix-xxxi. The songs were sung by Miss Cross and Mrs Verbruggen. Preface, Edition of 1696: I must inform the Reader, that this Third Part before it came upon the Stage was acknowledg'd and believ'd by all that saw it, and were concern'd (as well those that heard it read, as those that were Actors, who certainly, every one must own, are in their Affairs skilful enough to know the value of things of this Nature) to be much the best of all the Three Parts;...tho prepar'd by my indefatigable Diligence, Care, Pains, nay, the variety which I thought could not possibly miss the expected Success, yet by some Accidents happening in the Presentment, was disliked and explored; The Songish part which I used to succeed so well in, by the indifferent performance the first day, and the hurrying it on so soon, being streightned in time through ill management--(tho extreamly well set to Musick, and I'm sure the just Critick will say not ill Writ) yet being imperfectly performed, was consequently not pleasing; and the Dances too, for want of some good Performers, also disliked; all which, tho impossible for me to avoid, and not reasonably to be attributed any way to a fault in me, yet the noisy Party endeavour'd to use me as ill as if it were, till the generous Opposition of my Friends gave me as much reason to thank them for their Justice, as to despise the others Malice.... As to the Poppet Shew in the Fourth Act, the Accident of its being plac'd so far from the Audience, which hindred them from hearing what either they or the Prolocutor said, was the main and only reason of its diverting no better. A Comparison Between the Two Stages (1702) p. 17: Sullen: The third Part of Don Quixote. Ramble: Oh the ever-running Streams of Helicon! by all that's Poetical, my Friend Durfey; good lack! I thought I shou'd meet with him before we got half way: Well, in the name of Impudence, what luck? Sullen: Damn'd, Damn'd to all intents and purposes. Ramble: His first and second Part did well

Event Comment: Rich's Company. The date of the premiere is not known, but the fact that the play was advertised in the Post Boy, 12-16 Dec. 1695, suggests that it was probably first acted not later than November 1695. The edition of 1696 mentions two songs and their performers: A lass there lives upon the green, the words by an unknown hand, set by Courteville, and sung by the Boy to Miss Cross; and Bright Cynthia's pow'r divinely great, words by Mr Cheek, set by Courtevill, sung by Leveridge. These two songs are also in Deliciae Musicae, The Fourth Book, 1696, as is a third, Celemene, pray tell me, set by Henry Purcell and sung by the Boy and Girl. The words were written by D'Urfey; and the Boy presumably was Bowen, and the Girl, Miss Cross. See Purcell's Works, Purcell Society, XXI (1917), v-vi. A Comparison Between the Two Stages (1702), p. 19: Sullen: Oronooko. Ramble: Oh! the Favourite of the Ladies. Sullen: It had indeed uncommon Success, and the Quality of both Sexes were very kind to the Play, and to the Poet: No doubt it has Merit, particularly the last Scene; but 'tis as certain, that the Comick Part is below that Author's usual Genius. Ramble: I have a particular regard for Mr Southern's Stile and agreeable Manner; there's a Spirit of Conversation in every thing he writes. Sullen: I think very few exceed him in the Dialogue; his Gallantry is natural, and after the real manner of the Town; his acquaintance with the best Company entered him into the secrets of their Intrigues, and no Man knew better the Way and Disposition of Mankind. But yet I must say, his Diction is commonly the best part of him, especially in Comedy; but in Tragedy he has once in this, and in one other, Drawn the Passions very well

Event Comment: It is not known in which theatre this revival occurred. It was witnessed by van Constantijn Huygens, Monday 19 Dec. 1695 N.S. [translation]: In the afternoon I was at the comedy with my wife and Mrs Creitsmar. They played an old show called: The Love in the Tubb (Publications of the Dutch Historical Society, New Series, XXV [Utrecht, 1877], 560)

Event Comment: Rich's Company. The date of the first performance is not known, but the fact that the play was advertised in the Post Boy, 9-12 May 1696, suggests that it was first acted not later than April 1696. It may, however, have been first performed sometime earlier, for two songs for it were set by Henry Purcell, who had died in November 1695. See Purcell's Works, Purcell Society, XXI (1917), vi-vii. A Comparison Between the Two Stages (1702), p. 18: Pausanias, or Lover of his Country, Damn'd, tho writ by a person of Quality, and protected by Southern. One song, My dearest, my fairest, is a dialogue between Mr Cooke and Mrs Hodgson

Event Comment: In spite of decrees concerning the transfer of a player from one house to another, Dogget entered into an agreement with Rich's Company. See Nicoll, Restoration Drama, pp. 338-39. Cibber, Apology, I, 229: And the late Reputation which Dogget had acquired from acting his Ben in Love for Love, made him a more declared Male-content on such Occasions; he over-valued Comedy for its being nearer to Nature than Tragedy, which is allow'd to say many fine things that Nature never spoke in the same Words; and supposing his Opinion were just, yet he should have consider'd that the Publick had a Taste as well as himself, which in Policy he ought to have complied with. Dogget, however, could not with Patience look upon the costly Trains and Plumes of Tragedy, in which knowing himself to be useless, he thought were all a vain Extravagance: And when he found his Singularity could no longer oppose that Expence, he so obstinately adhered to his own Opinion, that he left the Society of his old Friends, and came over to us at the Theatre-Royal: This happened in the Winter following the first Division of the (only) Company

Event Comment: Betterton's Company. The date of the first production is not known, but the Songs were advertised in the Flying Post, 6-8 Dec. 1698, and the play in the London Gazette, 19-22 Dec. 1698; hence, the premiere was certainly not later than early December and was probably not later than November. In fact, on 5 Dec. 1698 Dr. William Aglionby wrote Matthew Prior, referring to Dennis, "a poor poet who has made us a fine entertainment of Rinaldo and Armida" (quoted in The Works of John Dennis, II, 489). In a dialogue written by John Oldmixon (Reflections on the Stage [London, 1699], p. 101) Savage, referring to Rinaldo and Armida, states: I have seen it 3 or 4 times already, but the Musick is so fine, and the Play pleases me so well, that I shall not think it a burthen [to see it again] (in The Works of John Dennis, I, 479). The Musical Entertainments in the Tragedy of Rinaldo and Armida (1699) is reprinted, with an introduction by Herbert Davis, in Theatre Miscellany (Luttrell Society Reprints, No 14, Oxford, 1953), pp. 103-15. One song, Ah queen, ah wretched queen, give o'er, sung by Gouge, is in Mercurius Musicus, 1699; and another, Jolly breeze that comes whistling, sung by Gouge, is in Twelve New Songs, 1699. A Comparison between the Two Stages (1702), p. 22: Critick: At last, (as you say) the old Stagers moulded a piece of Pastry work of their own, and made a kind of Lenten Feast with their Rinaldo and Armida; this surpriz'd not only Drury-lane, but indeed all the Town, no body ever dreaming of an Opera there; 'tis true they had heard of Homer's Illiads in a Nut-shel, and Jack in a Box, and what not?...Sullen: Well, with this Vagary they tug'd a while, and The Jolly-Jolly breeze-came whistling thro'-all the Town, and not a Fop but ran to see the Celebrated Virgin in a Machine; there she shin'd in a full Zodiack, the brightest Constellation there; 'twas a pleasant Reflection all this time to see her scituated among the Bulls, Capricorns, Sagittaries, and yet the Virgo still remain itacta....Critick: But this merry Time lasted not always; every thing has an end, and at length down goes Rinaldo's inchanted Mountain; it sunk as a Mole-hill seen on't: What a severity was this? that the Labour of such a gigantick Poet, nay Critick, shou'd give up the Ghost so soon: The renown'd Author thought himself immortal in that Work, and that the World was to last no longer than his Rinaldo; and tho' he stole every thing from the Italian, yet he said, what the Italian did was but Grub-street to his. See also 5 Jan. 1698@9 for a letter written by Mrs Barry, in part concerning Rinaldo and Armida

Event Comment: London Gazette, No 3444, 10-14 Nov. 1698: The Anniversary Feast of the Society of Gentlemen, Lovers of Musick, will be kept at Stationers-hall on St Cecilia's Day, being Tuesday the 22d Instant. According to a notice for a later concert (see 4 Jan. 1698@9) the music on this occasion was composed by Daniel Purcell
