Isis
According to the artist’s hieroglyphs, Isis is flanked by her son and her husband: At left, Harpocrates, ie Horus the Child; at right, Osiris-Re, the ram-headed composite god seen in the tomb of Nefertari. The picture is similar to paintings which represent the Coronation of the Virgin, with God and Christ both placing a crown on Mary.
