Over 110 complete and fragmentary Greek manuscripts containing various editions of the
Life of Andrew the Fool have survived, with the oldest being a fragment of a manuscript dating to the second half of the 10th century. The
Life says that Andrew lived during the time of
Leo I () as well as
Daniel the Stylite (died 493). Andrew, a
Scythian by birth, was a
slave of Theognostus, who was serving as a bodyguard in
Constantinople. Later, he decided to become a
fool for Christ, living out his goal with humility and patience. According to certain sources, Andrew had a vision of the Most Holy
Theotokos in the
Blachernae church of Constantinople, while the city was surrounded by enemy troops (by some sources, Muslim Arabs). Andrew and his disciple Epiphanius testified that they saw the
Holy Virgin surrounded by many angels and Saints, praying and extending her
omophorion (protection) over the faithful. After this vision, Constantinople was saved when its attackers retreated. That vision and the avoidance of Constantinople's destruction that was attributed to it inspired the creation of one of the most famous Eastern Orthodox holidays: the feast of the
Protection of the Theotokos. ==Veneration==
