Bartholomew ('son of Tholmai') is named among the Twelve in all three Synoptic lists and Acts. Most modern scholars and ancient commentators (from Augustine onward) identify him with Nathanael of John's Gospel — the man from Cana whom Philip brought to Jesus, and to whom Jesus said: 'Behold, an Israelite indeed, in whom there is no guile!' (John 1:47).
Tradition, attested by Eusebius citing Pantaenus, says he preached the Gospel as far as India, leaving behind a copy of Matthew's Gospel in Hebrew. Other sources direct his mission to Armenia, where he is one of the two co-founding apostles (with Jude) of what is the world's oldest Christian state — Armenia having been the first nation to adopt Christianity, in 301.
His martyrdom is uniformly described as gruesome: he was flayed alive and then beheaded by King Astyages of Armenia. His relics were translated from Armenia to the island of Lipari in 809, to Benevento in 838, and then to Rome in 983, where Otto III built the church of St. Bartholomew on the Tiber Island over them.
