His father Aurelius Victor Augentius, Pater Patrum of the Mitreo di Piazza S. Silvestro in Capite, dedicated an altar to the initiation of Emilianus as a sacred raven in 376, when he was still a child.
'These men held the rank of vir clarissimi, except for Aemilianus who is listed as a clarissimus puero, indicating he was only a child when he was initiated. Aemilianos also holds the unusual title of hierocoracica, which appears to be an alternative form of corax.'

This altar, now lost, mentions that the Pater Patrum passed on the attributes of the sacred Corax to his son.
