What books in the Bible did Paul write?

Paul did not write a book or epistle on his first missionary journey. In fact, it appears to have been quite a few years before he first wrote an epistle. In one of his earliest epistles, the Epistle to the Galatians, Paul said that after his conversion, he travelled to Arabia, then Damascus (bypassing Jerusalem), Jerusalem, then Syria and Cilicia, and back to Jerusalem. He must have spent 3 years in Damascus, 14 years in Syria and Cilicia, and indeterminate periods in the other centres, before he even wrote this epistle.
