 Plutarch's "Moralia" relates that, prior to Psammetichus I, the pharaohs did not drink wine nor offer it to the gods "thinking it to be the blood of those who had once battled against the gods and from whom, when they had fallen and had become commingled with the earth, they believed vines to have sprung".This was considered to be the reason why drunkenness "drives men out of their senses and crazes them, inasmuch as they are then filled with the blood of their forebears".Residue from five clay amphoras in Tutankhamun's tomb, however, have been shown to be that of white wine, so it was at least available to the Egyptians through trade if not produced domestically.
