Commemoration and the Loss of Her Life
The Orthodox Church in America's Lives of the Saints retains Anthusa's commemoration on August 27 but records that no information about her survives. The orthodox.net Menaion for the day likewise lists her among the commemorations without further detail. Her entry is therefore an honest stub: the Church continues to keep her memory even where the account of her life has not been handed down.
Liturgical witnesses that name her as Anthousa the New describe her martyrdom by drowning, recording that she was cast into a well for the faith of Christ. This brief notice is the only narrative element attached to her name in the available sources.
