Thomas the Apostle, also known as Didymus, was a first-century follower of Jesus and one of the Twelve Apostles. He is frequently identified by the epithet "doubting Thomas" due to his initial refusal to believe in the resurrection until he personally witnessed and touched the wounds of the risen Christ. Originally from Galilee, he is remembered as a significant missionary who traveled extensively to spread Christianity, eventually reaching India, where he is traditionally believed to have died in Mylapore.
