Book Illustration, L’antiquité expliquée et représentée en figures, vol. II, pt 1: Le culte des Grecs et des Romains, 1719
Pergolesi based many of his ornament designs on illustrations found in this 15-volume encyclopedia of the ancient world, compiled and published in the early 18th century. The antiquities the book represents are generally authentic; their use, however, is not always correctly identified. In this case, the encyclopedia illustrates three views of a tripod identified as a three-sided Roman altar dedicated to the god Mars. The actual marble object, probably made in the 1st century CE, is in fact the base of a candelabrum, not an altar. Several ancient versions of this tripod survive, including examples in the British Museum in London, England, and the Louvre Museum in Paris, France.
