A French expedition led by Christiane Zivie studied the inscriptions on the propylon and published their studies in 1992.[1] Between 1971 and 1979 archaeologists from the Waseda University of Japan worked on the site, they cleared the enclosure wall and the enclosed precinct from debris and excavated the temple's well which was filled with pottery shreds. Thirty-two strata of fillings were detected in the well, up to the point of 4 meters under ground level, where water made further excavation impossible. Remains found in the well prove that the well (and the temple itself) was already abandoned and used as a trash deposit by the Coptic era.[2]
