The model is mentioned twice in Jüchtzer's work records - referred to as Zephyr and Flora - between June and August 1786, and again between September and November of the same year. T.H. Clarke (op.cit., no,153) noted that the source could have been either the antique version of the group acquired by Augustus the Strong in 1728 from the Chigi Collection in Rome, or more likely the cast in the Mengs Collection. Of Jüchtzner's designation of the group as Zephyr and Flora, Clarke observed (p.47), "Why Jüchtzer should call this well-known group after the Antique by this title is strange. It is an error into which Kaendler would never have fallen, having been well educated by his father in classical mythology."
