Cyprian, metropolitan bishop of Tarragona, was active from the Thirteenth Council of Toledo in 683 to the Fifteenth Council in 688. It is supposed that his mortal remains lie in an alabaster casket-ossuary placed in the interior wall of the apse of Tarragona’s cathedral. But the casket-ossuary and its inscription with the bishop’s epitaph, have to be dated in 1460. The aim of this paper is to provide a new edition of this inscription (= CIL II, 2/14, 2088); and to demonstrate, through lexical and structure analysis and through latin epigraphic parallels, that the 1460 inscription it’s based in the original inscription devoted to the bishop after his death (terminus ante quem 693, when his successor, Vera, signed as metropolitan in the Sixteenth Council of Toledo). If we are right, this will be the fi rst metropolitan bishop of Tarragona to be documentated through his, even in a copy, preserved epitaph.
