The present picture was accompanied until 1972 by a pendant, also signed and dated 1739 (Arisi, loc. cit., no.279, illustrated). As Professor Arisi points out, 'Questi due dipinti rappresentano bene un momento particolarmente fervido e ampiamente documentato'. Three drawings for individual figures in the present painting are in the Kupferstichkabinett, Berlin (nos.15463, 17539 and 17542), including a particularly fine sketch for the more prominent woman, and a number of derivative works are recorded. A pair of late replicas of the two pictures is in a Roman private collection and another pair, executed with studio assistance and of square format, is in an American private collection. In 1749 Panini executed a painting containing elements from both capricci (idem, p.426, no.392, illustrated), and the man admiring the Farnese Hercules on the left is copied in a picture formerly in the collection of Dr. Ottavio Poggi, Rome, which Arisi attributes to Charles-Louis Clérisseau
