The spring of Kallirhoe is probably the spring described in the 1894 Baedeker guide (pg. 51): "To the S. of the Olympieion runs the bed of the Ilissos (p. 49), with the remains of a wharf or quay. The polished surface of a ridge of rock that crosses the stream here also seems to betray the action of water at a former period. To the S. is the Chapel of St. Photini, a visit to which is amply repaid by the fine view of the Acropolis and the Olympieion. Below, on the margin of the Ilissos, the spring of Kallirhoë (Pl. F, 8) issues from the rock and is still called Kallirói ('pleasantly flowing'). Narrow channels in the rock originally supplied it more abundantly with water." [Note]
