Event Comment: "Henderson's Iago was perhaps the crown of all his serious achievements. It was all profoundly intellectual like the character. Any thing near this, I have never seen...The most perplexing difficulty in the [character] is to turn the inside of design outward to the spectators, and yet externally seem to be cordial and sincere and interesting among the victims-it demands an instant versatility, that yet must not savour of trick. You must hear his insinuations with curses, and yet confess that you also would have been deceived. Other Iagos were to be seen through at once...Though a studious man, there was no discipline apparent in the art of Henderson; he moved and looked as humour or passion required...[He] cared little about the measure of the line; he would not consider the fame of the versifier while the heart was to be struck' (Boaden, Siddons, II, 28-29, 49).
