Commemoration and Tradition
The Synaxarion preserves an acrostic verse for the two martyrs, rendered in one source as: "Basilides with Gerontios by the sword, partook of rewards from the Word who is King of all." The surviving descriptions of their lives are drawn from liturgical tradition and from the Laura Codex I 70.
A church dedicated to the Holy Martyr Gerontios is recorded to have stood in Constantinople until the end of the 14th century, evidence of an established local veneration.
One textual note observes that a separate April 13 commemoration of Saints Theodosia the Princess and the Eunuch Gerontios — not found in the principal synaxaria of the Church — is probably a later doublet of the April 1 martyrs, arising from name similarity, since Theodosia is styled the Vasilissa (Princess), a form close to the name Basilides.
