Saint Hyacinth, Saint Vincent Ferrer and Saint Luis Beltrán. Etching by F. Bartolozzi after G.B. Piazzetta.

Identified in the lettering as Saint Isidore (of Chios?), Saint Vincent Ferrer and Saint Hyacinth. The man seated on the right is identified in the lettering as Saint Hyacinth. According to Mariuz, loc. cit., he is Saint Luis Beltrán: he wears the Dominican black cloak over a white habit, and holds a chalice with snakes, which refers to the attempted poisoning of Luis by the Caribs to whom he was sent as a missionary. The man in the centre is identified both in the lettering and by Mariuz as Saint Vincent Ferrer: he wears the white habit of the Dominicans without the black cappa or overcoat, and his attribute is a flame above his head. The standing man on the left is identified in the lettering as Saint Isidore, but neither Saint Isidore of Chios nor Saint Isidore of Seville was a Dominican: they both predate the Dominican order. He is identified by Mariuz as Saint Hyacinth, a Dominican friar sent from Rome as a missionary to his native Poland (Silesia). He is holding the Host and a statue of the Virgin and Child which he had rescued from a Mongol attack on Kiev in 1240. He is wearing a Dominican overgarmentt
