Emerald’s Greek name was probably Smarágda (Σμαράγδα), although derivations can also be found such as Smarágdi, Smaroula and Smaragdoula. As well as referring to the precious stone, the name is also revered in the Greek Orthodox Church, being the name of one of the Forty Martyrs of Sebaste (Ancient/Katharevousa Greek Ἃγιοι Τεσσεράκοντα; Demotic: Άγιοι Σαράντα) who were a group of Roman soldiers in the Legio XII Fulminata (Armed with Lightning) whose martyrdom in 320 for the Christian faith is recounted in traditional martyrologies. They were killed near the city of Sebaste, in Lesser Armenia (present-day Sivas in Turkey), victims of the persecutions of Licinius, who after 316, persecuted the Christians of the East. The earliest account of their existence and martyrdom is given by Bishop Basil of Caesarea (370–379) in a homily he delivered on their feast day. The Feast of the Forty Martyrs is thus older than Basil himself, who eulogised them only fifty or sixty years after their deaths.
