Constantine departed on 5 October 710. In Constantinople, Constantine stayed in the Placidia Palace, which had formerly been occupied by Pope Vigilius in 547, the representatives of Popes Martin I and Agatho (while attending the Third Council of Constantinople). Eleven of Constantine's thirteen companions who can be identified by name (two bishops, three priests, and all the ranking members of the papal chancellery and household) were also of Eastern extraction. Also accompanying Constantine was the future Pope Gregory II, then a deacon, and another Latin subdeacon Julian. Constantine specifically chose attendants who were "cut from similar cloth" as he, and likely to be sympathetic to the East.
