there are few biographical details concerning the life of saint isidora. most of what is known can be found in the lausiac history(historia lausiaca) written in 419-420 by palladius of galatia, at the request of lausus, chamberlain at the court of the byzantine emperor theodosius ii. while other texts from this time mention the story of st. isidora, the lausiac history is the most commonly referenced text about the saint's life.
