Under Nectanebo II, Egypt prospered. During his reign, the Egyptian artists developed a specific style that left a distinctive mark on the reliefs of the Ptolemaic Kingdom.[6] Like his indirect predecessor Nectanebo I, Nectanebo II showed enthusiasm for many of the cults of the gods within ancient Egyptian religion, and more than a hundred Egyptian sites bear evidence of his attentions.[7] Nectanebo II, however, undertook more constructions and restorations than Nectanebo I, commencing in particular the enormous Egyptian temple of Isis (the Iseum).
