(1790), in
Pinacoteca Querini Stampalia The church was initially attached to a
Benedictine monastery of
nun, which was also founded by Participazio and various other doges of the family. The nuns of this monastery mostly came from prominent noble families in the city and had a reputation for laxness in their observance of the monastic enclosure. The
abbess was usually related to the doge. In 855,
Pope Benedict III took refuge in the monastery while fleeing the violence of
Anastasius Bibliothecarius, whose election as Pope his supporters had challenged. Out of gratitude, Benedict III gave the nuns an extensive collection of
relics, which was the foundation of a comprehensive collection for which the monastery was famed. Among these were those of
Athanasius of Alexandria and a piece of the
True Cross. In 1105, a devastating fire destroyed the entire monastic complex. According to chronicles of the time, some one hundred nuns who had taken refuge in the monastery's cellars died from smoke inhalation. Under the direction of
Enrico Dandolo, the convent was
reformed into a Cluniac house. The monastery had the tradition of being visited by the doge and his entire court annually at
Easter in a ceremony which included the presentation of the
corno ducale, the insignia of his office. This tradition is said to have begun in the 12th century after the nuns had donated land for the building of a ducal chapel, now
St Mark's Basilica, and ended only in 1797, at the end of the
Republic, when the monastery was suppressed by the invading forces of Napoleon's army. ==Interior==
