Timaeus is the father of the blind beggar Bartimaeus ('son of Timaeus') healed by Jesus in Mark 10:46. The Aramaic name likely derives from the Hebrew root for 'unclean' or 'polluted,' though this is uncertain. Mark preserves both the Aramaic patronymic and its Greek translation, giving readers the actual name used in the community. Cross-linguistic evidence shows consistent transliteration (Timaeus, Timaîou, Timée, Timaeos), recognizing this as a personal identifier. The detail humanizes the miracle—this beggar had a name, a father, an identity.
