The bluest that I know from personal experience is that at Thermopylae
, not all of it, but that which flows into the swimming-baths, called locally the Women's Pots. Red water, in color like blood, is found in the land of the Hebrews near the city of Joppa
. The water is close to the sea, and the account which the natives give of the spring is that Perseus, after destroying the sea-monster, to which the daughter of Cepheus was exposed, washed off the blood in the spring.
