When the Dorians were now in possession of Lacedaemon and Argos, it is said that Preugenes, in obedience to a dream, stole from Sparta the image of our Lady of the Lake, and that he had as partner in his exploit the most devoted of his slaves. The image from Lacedaemon is usually kept at Mesoa, because it was to this place that it was originally brought by Preugenes. But when the festival of our Lady is being held, one of the slaves of the goddess comes from Mesoa bringing the ancient wooden image to the precinct in the city.
