Monastic life and iconography
Joseph belonged to the Dionysiou Monastery, a coenobitic house on the southwest coast of Mount Athos founded by Saint Dionysius of Korisos in the mid-14th century, dedicated to John the Baptist, and ranking fifth in the hierarchy of the self-governing Athonite monasteries.
The synaxarion remembers him both for his monastic virtue and for his craft as an iconographer. The work most closely tied to his memory is the icon of the holy Archangels on the iconostasis of the monastery's main church, the one concrete artistic attribution that the surviving accounts preserve.
