Peter of Siena (died 1321)

[1] In 1320, Peter left Hormuz with his fellow Franciscans James of Padua and Thomas of Tolentino, the Dominican Jordan of Severac, and the layman Demetrio da Tifliz.

[2] A Georgian or Armenian, Demetrius was proficient at languages and served as the group's interpreter.

[3] A storm forced the party to land at Thane[4] on Salsette Island[2] near Mumbai in India[3] en route, and they were greeted by local Nestorians.

Thomas, James, and Demetrius had gone to the court while Peter remained behind to look after their things.

Having begun a discussion of religion, the qadi had asked them their opinion of Muhammad and Thomas replied bluntly that he was "the son of perdition and had his place in Hell with the Devil his father".
