From the beginning of the article:
The lead tablet from Selinous, published by Jameson, Jordan, & Kotansky in 1993 and dated to about 460 BC, is remarkable in many respects: in a dialect and orthography hardly known before, it presents one of the oldest Greek leges sacrae we have, full of unique details for early Greek ritual. The tablet was found through illegal excavations, no doubt with metal detectors, most probably in the sands around the Malophoros sanctuary, and sold to the Paul Getty Museum at Malibu. Its provenance is proved beyond doubt by the reference to the “Milichios of Mysqos” (A 9) – the Milichios stele of Mysqos from Selinous had been in the Palermo Museum for a long time. In consequence, the tablet has been given back to Italy recently, but thanks to its international Odyssey it has been provided with an excellent and uncommonly prompt edition.
