Event Comment: The King's Company. The date of the premiere is not certain. This performance is known from an entry in the Newdigate newsletters, which also states that Rollo was to be acted on the following Monday. If this statement is accurate, the performance of The Loyal Brother on 4 Feb. 1681@2 may be the third night rather than the opening performance. Newdigate newsletters, 4 Feb. 1681@2: On Monday morn [the Moorish Ambassador] & ye Comers meet to conclude ye treaty and in ye afternoon goes to see Rollo D. of Normandy at ye Ks playhouse wre ye K was this afternoon to see ye new play calld ye Loyall brothr (Wilson, More Theater Notes from the Newdigate Newsletters, p. 59). The Prologue and Epilogue were printed separately and have been reprinted in Wiley, Rare Prologues and Epilogues, pp. 70-72. Luttrell acquired his copies (Huntington Library) on 7 Feb. 1681@2. In The Life of John Dryden (Chapel Hill, 1961), Charles E. Ward believes (pp. 166, 355) that The Loyal Brother was first acted in the autumn of 1681; but the entry in the Newdigate newsletters seems to make February 1682 the more probable time
