his appointment as governor to her eldest son, and of his marrying a lady of her suite. From thence he went to reside at Rome, about 1567, and died in Tuscany, in 1576. [Footnote *151: On Muzio, see GIAXICH, _Vita di Girolamo Muzio_ (Trieste, 1847); MORPURGO, _Girolamo Muzio_ (Trieste, 1893), NOMI, in _Miscellanea Stor. della Valdelsa_, No. 24; NOTTOLA, _Appunti sul Muzio poeta_ (Aosta, 1895).] Tiraboschi declines the task of compiling the long catalogue of his various writings, in poetry, sacred and profane history, moral essays, and familiar letters,[*152] nor need we undertake it. A large portion of his works were directed against protestant doctrines, and, having reformed the habits of his somewhat stormy youth, he lent willing and efficient aid in strangling the progress of Calvinism in Italy, after a protracted struggle, upon which the investigations of Dr. M'Crie have thrown much valuable light. Muzio is alleged to have exhibited in this contest more of martial dexterity than theological acumen; but his controversial effusions, being published in Italian, and clothed in a homely slashing style, were probably supposed quite as efficacious against the progress of heretical opinions among his countrymen, as the disquisitions of more profound theologians. It was not, however, for the dogmas of faith alone that Muzio wielded his pen. The soldier of fortune was quite as happy, and more at home, on topics belonging to the chivalry of his profession. His treatises on Duels and the Point of Honour were suited to the spirit of the age, and had in consequence a considerable run of popularity, now of course long ago past. The like fate has befallen his didactic poem on the Art of Poetry, in the literature of his own country. What most concerns us are his Lives of Dukes of Urbino. That of Federigo is dedicated to Guidobaldo II., and the original is deposited in the Vatican Library. Having been compiled with considerable care, it continues our best narrative of his reign, and has been greatly drawn upon by Baldi and Riposati. The edition printed at Venice in 1605 is but an abridgment, containing less than half the original matter. His Life of Francesco Maria I. was left unfinished, and remains unedited in the Vatican.[153] [Footnote *152: The fullest collection of his letters seems to be that of GIOLITI, 1551. Cf. also ZENATTI, _Lettere inedite_ (Capodistria, 1896).] [Footnote 153: Vat. Urb. MSS. No. 1011, and No. 1023, f. 50.]
