saint isidora or isidore (saint isidora the simple, saint isidora of tabenna, saint isidora of egypt, isidora the fool of egypt, saint isidora fool for christ, blessed isidora the fool of tabenna in egypt) was a christian nun and saint of the 4th century ad. she is considered among the earliest fools for christ. while very little is known of isidora's life, she is remembered for her exemplification of the writing of st. paul that “whosoever of you believes that he is wise by the measure of this world, may he become a fool, so as to become truly wise.”. the story of isidora effectively highlights the christian ideal that recognition or glory from man is second to one's actions being seen by god, even if that means one's actions or even one's self remains unknown or misunderstood. this ideal was extremely important to the early desert fathers and mothers who recorded isidora's story.
