TREZZO, Jacopo da
Italian medallist, sculptor, gem-engraver and jeweller. Nothing is known of his background and early life. His family apparently came from Trezzo sull’Adda but were living in Milan at the time of his birth. By 1550 he had achieved a level of fame that deserved mention in the first edition of Vasari’s Vite. His activities in Milan, in which city he lived until 1555, included gem-engraving and the fabrication of objects in precious and semi-precious stones for Cosimo I, Duke of Florence.
Between 1548 and 1578 Jacopo produced eleven medals, including variants, eight of which are signed. The first of these is the medal of the Cremonese engineer Gianello della Torre, of which one example bears the date 1548.
While in Milan, Trezzo produced two signed medals (both Victoria and Albert Museum, London), doubtless commissioned by the Governor of Milan, Ferrante Gonzaga. One was of Gonzaga’s wife, Isabella de Capua, Princess of Molfetta (d. 1559), and the other of their daughter, Ippolita Gonzaga (1535-1563), dated by the age of the subject to 1552. The medal of Isabella de Capua recalls the placid strength of the Gianello della Torre medal, as well as having similar drapery.
In 1555 Trezzo moved to the Low Countries, probably to Brussels, in the service of Philip II of Spain, who had also become the ruler of Milan. The documentation of Trezzo’s move indicates that he carved two seals for Philip in 1557. He also produced his most beautiful medallic portrait, that of Mary I of England (reg 1553-58, British Museum, London), who married Philip in 1554. Its pendant is a medal of Philip II, signed and dated 1555, of which there are two variants (Florence, Bargello).
In 1559 Trezzo followed Philip to Spain, where he apparently spent the rest of his life. Trezzo also produced important work on a larger scale, for example a lectern in Plasencia Cathedral and decorative sculpture at the Capilla Mayor at El Escorial, near Madrid , for which he carved the great tabernacle of the high altar (1579-86) from designs by Herrera.
Trezzo’s son Jacopo da Trezzo II (d. 1607) was also a sculptor.
