Portrait medal of Isotta degli Atti (obverse); An Elephant (reverse). Artist: Matteo de' Pasti (Italian, Verona ca. 1420-after 1467 Rimini). Dimensions: Diam. 8.5 cm, wt. 275.79 g.. Date: model 1446 or later (possibly cast 16th century).A beautiful merchant's daughter, the thirteen-year-old Isotta degli Atti inspired the passion of Sigismondo Malatesta, the ruler of Rimini. The date 1446 commemorates the year Sigismondo consolidated his political power and won Isotta as his mistress; she later became his wife. Sigismondo embedded portrait medals of himself and Isotta in the walls of his buildings as a legacy of his triumphant reign. Here, Matteo captures the teenage beauty with tenderness and sensitivity. The elephant portrayed on the medal's reverse is a masterpiece of animal representation, at once naturalistic and richly symbolic. As one of the favorite heraldic devices of the Malatesta family of Rimini, the elephant signifies regal strength and the fame that confers immortality.
