St Mary Eleousa (First Mesembria charter)
Prizing the monks' prayers “above gold and precious stone,” the tsar frees the monastery of St Mary Eleousa and all who live in its precincts from every due — angaria, psomozimia, wall-building — exempts its boat from toll for ever, bars the duke and the townsmen from burdening it, and orders the archbishop to stay out, his name only to be commemorated. Signed “Ivan Alexander, in Christ God faithful tsar and autocrat of Bulgarians and Greeks,” in April, ninth indiction.
