In the liturgy, they are referred to as "the forty-nine martyrs, the elders of Shiheet". The main source for the martyrdom of the Forty-Nine is the account in the Synaxarium itself. There is also a short notice of the burial and afterlife of the martyrs, the Coptic Depositio XLIX martyrum (Interment of the Forty-Nine Martyrs).
