Career
He is known from his cenotaph, which was discovered in 1620 in Birten (now a part of Xanten), Germany. Caelius is depicted wearing his military uniform, with phalerae (a type of military decoration), armillae (a type of bracelet), and a corona civica (an award for saving a fellow citizen"s life), while in his right hand, he holds a vitis (carried by all centurions). On either side of his image are his freedmen (ex-slaves), Privatus and Thiaminus.
The tombstone"s lower left corner is damaged, but enough survives to determine that the text below the image once read:
