Marco Moro
The Trinity and All Saints

16th century
High altar at the Church of All Saints (Ognissanti), Venice

The painting features an early example of the representation of the Trinity as a dove between the seated Father and Son, the latter holding his Cross. The chief saints portrayed are the Virgin Mary (center, kneeling on a sort of parapet), St. John the Baptist (left, pointing to the Trinity and dressed only in his camel hair), St. Peter (right of John, key and book in left hand), St. Sebastian (on the right, arrows in left hand), St. Jerome (right of Sebastian, red garment, building in arm, lion at feet).
