Easton's 1897 Bible Dictionary:

Clement
   mild, a Christian of Philippi, Paul's "fellow-labourer," whose
   name he mentions as "in the book of life" (Phil. 4:3). It was an
   opinion of ancient writers that he was the Clement of Rome whose
   name is well known in church history, and that he was the author
   of an Epistle to the Corinthians, the only known manuscript of
   which is appended to the Alexandrian Codex, now in the British
   Museum. It is of some historical interest, and has given rise to
   much discussion among critics. It makes distinct reference to
   Paul's First Epistle to the Corinthians.
