During the Byzantine era, which lasted from the 4th to the 15th century AD, the name Sinthia gained popularity among the Eastern Orthodox Christian community.

According to historical accounts, Saint Sinthia was a young woman who was persecuted for her faith and ultimately executed for refusing to renounce her beliefs.
