Rabban Bar Sauma traveled with a large retinue of assistants, and 30 riding animals. Companions included the Church of the East Christian ("archaon") Sabadinus; Thomas de Anfusis (or Tommaso d'Anfossi), who helped as interpreter and was also a member of a famous Genoese banking company; and an Italian interpreter named Uguetus or Ugeto (Ughetto). Bar Sauma likely did not speak any European languages, though he was known to be fluent in Chinese, Turkic, and Persian, and he was able to read Syriac. Europeans communicated to him in Persian.
