Veneration and Sources
Despite the scarcity of biographical detail, Zenaida's name is attested across a range of liturgical and hagiographic witnesses. Her veneration was widespread in Constantinople, where a church was dedicated to her in the district associated with the Basilisk; in that city her synaxis was kept on June 6, the day before her general commemoration.
Her memory is recorded in a ninth-century Neapolitan calendar under June 7, in a printed Greek Menaion published at Venice in 1591, in the Synaxaristes of Saint Nikodemos of the Holy Mountain, and in the Byzantine Synaxarion. The Roman Martyrology compiled by Cardinal Caesar Baronius also notes her, though it assigns an erroneous date of June 5.
The Orthodox Church in America appoints a troparion and kontakion for her commemoration that address her as a martyr who received an incorruptible crown through her sufferings, reflecting her established standing in the liturgical tradition.
