Michael Angelo's relation to Messer Tommaso de' Cavalieri presents the most interesting parallel to the attitude which Shakespeare adopted towards William Herbert. We find the same expressions of passionate love from the older to the younger man; but here it is still more unquestionably certain that we have not to do with mere poetical figures of speech, since the letters are not a whit less ardent and enthusiastic than the sonnets. The expressions in the sonnets are sometimes so warm that Michael Angelo's nephew, in his edition of them, altered the word _Signiore_ into _Signora_, and these poems, like Shakespeare's, were for some time supposed to have been addressed to a woman.[2] On January 1, 1533, Michael Angelo, then fifty-seven years old, writes from Florence to Tommaso de' Cavalieri, a youth of noble Roman family, who afterwards became his favourite pupil: "If I do not possess the art of navigating the sea of your potent genius, that genius will nevertheless excuse me, and neither despise my inequality, nor demand of me that which I have it not in me to give; since that which stands alone in everything can in nothing find its counterpart. Wherefore your lordship, _the only light in our age vouchsafed to this worlds_ having no equal or peer, cannot find satisfaction in the work of any other hand. If, therefore, this or that in the works which I hope and promise to execute should happen to please you, I should call that work, not good, but fortunate. And if I should ever feel assured that--as has been reported to me--I have given your lordship satisfaction in one thing or another, I will make a gift to you of my present and of all that the future may bring me; and it will be a great pain to me to be unable to recall the past, in order to serve you so much the longer, instead of having only the future, which cannot be long, since I am all too old. There is nothing more left for me to say. Read my heart and not my letter, for my pen cannot approach the expression of my good will."[3] Cavalieri writes to Michael Angelo that he regards himself as born anew since he has come to know the Master; who replies, "I for my part should regard myself as not born, born dead, or deserted by heaven and earth, if your letters had not brought me the persuasion that your lordship accepts with favour certain of my works." And in a letter of the following summer to Sebastian del Piombo, he sends a greeting to Messer Tommaso, with the words: "I believe _I should instantly fall down dead_ if he were no longer in my thoughts."[4] Michael Angelo plays upon his friend's surname as Shakespeare plays upon his friend's Christian name. These are the last lines of the thirty-first sonnet:-- "Se vint' e pres' i' debb' esser beato, Meraviglia non è se, nud' e solo, Resto prigion d'un _Cavalier_ armato."
