As part of his Santa Maria del Priorato commission, Piranesi designed the piazza in front of the church. On one side of the square, a high wall screened the garden of the Knights of Malta. On the opposite side, Piranesi created a matching wall paneled with high stucco reliefs. This drawing is a final design for one such relief. The Maltese cross at center is the symbol of the knights; the lyre and panpipes were Etruscan symbols for Piranesi, and he included them as a reference to the Aventine Hill's legendary history as a site of Etruscan cult practices. The towers in the medallions are a reference to the Rezzonico arms, in recognition of Piranesi's patron.
