Modern name for a site in southern Upper Egypt on the west bank of the Nile, ancient Egyptian Iunet, Greek Latopolis. The surviving temple dedicated to Khnum dates to the Ptolemaic Period and Roman Period and includes a relief of Septimius Severus with his family, in which the image of his younger son, Geta, has been erased by the order of his older brother, Caracalla, who murdered him. Esna was excavated by the British archaeologist John Garstang from 1905–1906 and since 1951 has been excavated and the temple inscriptions copied by a French expedition.
