Leaving the theatre behind us, after we pass the Agora there is a large building: the Fountain of Arsinoe mentioned also by Pausanias. Who was this maiden, Arsinoe, perhaps a water nymph? According to one version of the myth, Arsinoe was the daughter of the King of Messene Leucipo and mother of Asclepius. This fountain that was built at the end of the 3rd century BCE has a tank of 40 meters length and a colonnade of Ionic semi-columns. At the middle of the composition there were bronze statutes of Roman emperors.
However, mythical narrations connect the Fountain of Arsinoe with the literature around the source of Klepsydra and Zeus' adventures. Klepsydra supplied and still supplies until today the Fountain of Arsinoe with water. The first who mentions it is Pausanias.
According to the ancient traveller, when the Kourites the protectors of divine births abducted Zeus as an infant to save him from his father Saturn, they delivered him to two local nymphs: Ithomi and Neda. These two nymphs haunt the land of Messene constantly: Neda with its waterfall and Ithomi with the sanctuary of Zeus. Arcadia and Messene are haunted by the adventures of Zeus bathing with nymphs, sometimes in river Lousios, sometimes in the springs. Zeus is a nymph-ridden god; they either abduct him or he roams around with them during the night. Here the two nymphs bathed the divine baby at Klepsydra spring to save it. The spring took its name from the combination of two words: klepto, "to steal" and ydor, "water". Later on, other new meanings were attributed to the spring and are connected mainly with the crystal-clear water that constantly flows into the village Mavromati, offering a cool feeling to visitors and travellers until today.
