ACHILLEO, bishop of SPOLETO. - He was chosen by the imperial court of Ravenna in 419 to perform the Easter functions at Rome, which at that time was without its bishop, since Bonifacio I and his rival Eulalio had been removed from it (cf. Avellana Collectio, letters 21, 22 [ad A.], 23, 24, 29, 31, 32 of 15, 23, 26, 29 March 419; ed. O. Günther, in CSEL 35, 1, Vienna 1895, pp. 68-71, 74-79).
G. B. De Rossi attributes to him, on good grounds, 4 epigrams preserved, without any topographical indication, in the Centulense epigraphic collection (poems 10-12, incomplete and confused with those of the basilica of S. Pietro) and in the Laureshamense IV collection (poems 79-82, complete), also called Palatina, from the cod. Vat. Pal. lat. 833, which contains II. They should refer to the church of S. Pietro extra moenia at Spoleto, situated on the Via Flaminia and built precisely by A. That this church existed in the fifth century is confirmed by several inscriptions of Spoleto bishops of the same century buried there.
Poems 80 and 82 of the Laureshamense IV (10, incomplete, and 11 of the Centulense) deal with the Primacy of Pietro with considerable effectiveness.
