The membership of Orazio Sansedoni and his nephew Francesco in the Order of the Knights of Malta prompted these Sienese noblemen to commission from the Florentine painter Giovanni Domenico Ferretti, in 1750, the portraits of two Turkish governors, the Count de Bonneval and Mustafa Pasha, painted then copied by Francesco Gambacciani. The discovery in a private collection of a 'Portrait of Count de Bonneval', signed by the Florentine female artist Violante Siries Cerroti and executed in the same span of months in which the above-mentioned canvases were completed, must be attributed to the same patrons. The present article documents this painter's ongoing connection with the Sansedoni family and demonstrates the importance of a work that has remarkable similarities with the portraits of Bonneval executed by Liotard, seeking to shed light on the genre of the 'turqueries' that celebrated the West's deep fascination with the Orient and with those exponents of the Ottoman empire who took part in major historical events.
