Zephyrus, according to the apocryphal Letter to Aristotle 14 (See Secretum Secretorum), was the soldier, who brought Alexander the Great a helmet full of water when the army was suffering greatly in the Gedrosian desert (325 BC) . The famous story of how Alexander poured the water into the ground in front of the army is told by a number of sources but the name Zephyrus ( western wind ) appears to have been invented.
