Signed and dated 1360, the subject is the Trinity with saints Zeno, John the Baptist, Peter and Paul; the Coronation of the Virgin appears in the compartment above and figures of angels, saints and prophets adorn the frame.

Of Milanese origins, Turone was one of the first of a succession of Lombard artists and artisans who immigrated to Verona up through the 18th century. He established a large, flourishing studio that dominated local painting at the middle of the 14th century, bringing about the shift from the Giottesque style to a more modern Gothic one. His shop was active in every painting technique from fresco to manuscript illumination, and he received the commission for the great choir books for the cathedral of Verona.
