Нехо II
Although Herodotus (2.158) tells us Darius I continued work on the canal, Aristotle (Aristot. met. I 14 P 352b.), Strabo (Strab. XVII 1, 25 C 804. 805.), and Pliny the Elder (Plin. n. h. VI 165f.) all say that he failed to complete it, while Diodorus Siculus does not mention a completion of the canal by Necho II.
