(Agostino de), a noted engraver, better known by the name of Agostino Venetiano, or in England by that of "Augustin the Venetian;" but Musis was his proper family name. He was a native of Venice, and scholar of Marc Antonio Raimondi. It is not certain at what period he began his studies under that celebrated master; but the first dated print by Agostino appeared A.D. 1509, at which time, it is probable, his tutor still resided at Venice. After the death of Raphael, which happened in 1520, Agostino de Musis, and Marc de Ravena, his fellow-disciple, who had conjointly studied each other, separated, and worked entirely upon their own account. It is uncertain at what time Agostino died; but his prints are not dated later than 1536. So that it may be reasonably supposed that he did not long survive that period. Agostino de Musis imitated the style of his master with great attention, and was, upon the whole, the most successful of all his scholars. In neatness and mechanical execution with the graver, he has often equalled if not sometimes exceeded him; but in point of taste, and in the purity and correctness of outline, he certainly fell greatly short of him. Agostino's drawing had more of manner and stiffness; the heads of his figures are not so accurately marked; nor the other extremities expressed with equal truth.
