In February 1799, Denon’s party reached Philae, just north of the Nile’s first cataract. The 51-year-old artist was exhausted yet predictably thrilled by this view of the sandstone temple of Isis, which remained in use from 380 B.C. to 300 A.D. Philae was a cult center for Isis—Osiris’s sister-wife and symbolic mother of the pharaoh. Today the site lies beneath the waters of Lake Nasser, but its temples were salvaged and reconstructed on a nearby island that was regraded and landscaped to resemble the original Philae.
