Died after 552. The Briton Saint Aaron crossed into Armorica (Brittany)
and lived as a hermit on the island of Cesambre, called Saint Aaron
until 1150 and now Saint Malo. The island was separated from Aleth by an
arm of the sea, which the tide at low water left dry twice daily.
Eventually Aaron was joined by a group of disciples and became their
abbot. Among the disciples was Saint Malo, who arrived from Wales about
the middle of the 6th century and was warmly welcomed. A parish church
in the diocese of Saint Brieuc bears Aaron's name
(
Benedictines,
Husenbeth).
