Constantius, vir illustris

Constantius, distinguished by the rank vir illustris (the highest grade of the late-Roman senatorial aristocracy), was a high-ranking official and correspondent in Ostrogothic Italy during the late fifth and early sixth centuries. He is known chiefly as a recipient of letters from Ennodius, deacon and later bishop of Pavia, and appears in the milieu of the administration documented by Cassiodorus, placing him among the Italo-Roman senatorial elite who served the Ostrogothic court at Ravenna under Theoderic the Great. Beyond the secure indication of his elevated senatorial rank and his appearance as a correspondent, the specific offices, dates, and biography of this Constantius are not firmly established; the name was common, and he is attested mainly through the surviving correspondence rather than independent narrative sources.
