The frogs

One of the sounds many visitors to Athens missed was the water of the river Illissus, which flowed next to the Temple of Olympian Zeus. The famous river of antiquity, on the banks of which Socrates had walked, had become a seasonal torrent, which flooded its usually dry riverbed only when it rained heavily. However, even this little water was enough to sustain a noisy colony of frogs, which gave the rocks near the church of Agia Fotini the name Frog Island (Vatrachonisi).
