 Olybrius also restored, at his own expense, the nearby church of Saint Euphemia in Chalcedon, a famous church that had been chosen by Pulcheria, sister of Theodosius II, for the Council of Chalcedon in 451.This choice was a sign of the bond between Olybrius, a Roman senator, with the imperial House of Theodosius.In 1707, Apostolo Zeno and Pietro Pariati wrote a "libretto" entitled "Flavio Anicio Olibrio".
