The Catino and Vault at San Pietro, Venice
Girolamo Pellegrini
Circa 1695
The image in the vault is labeled The Glory of the Most Holy Trinity. It adapts the Trinity iconography that had become usual by the end of the 17th century, with the Son holding a cross and sitting to the right of the Father, but instead of putting the dove of the Holy Spirit between them the artist displaces it to the apex of the image in the catino, The Glory of St. Lorenzo Giustiniani. There St. Catherine points Lorenzo's attention toward the dove and thus to the entire Trinity while she and St. Peter help him rise toward Heaven.
St. Lorenzo is identified by his patriarchal cross and close-fitting cap, St. Peter by his keys, and St. Catherine by her crown and golden hair.
The theological virtues are represented lifting Lorenzo toward Heaven: The anchor at the hip of the woman at his foot signifies Hope, the woman at his right with the children at her breast is Charity, and the behind him with her hand on his book is Faith. The figure behind Charity may be a combination of two of the "cardinal" virtues: fortitude by the helmet and prudence by the mirror in the figure's hand.
