I am undertaking some research on material from Sicily. I noticed that the gorgon antefix acquired by the J. Paul Getty Museum in 1972 (inv. 1972.AD.124) has no stated donor. Birgitta Wohl, who published the antefix in 1977 [JSTOR], noted that there were two other antefixes "from the same mold" that had surfaced on the Swiss market (Galerie Heidi Vollmoeller) in 1975.
Did all three antefixes surface together? What was the "collecting history" of the Getty antefix? Where were they originally displayed? Was the building in Gela?
