Pausanias Description of Greece 9.24.3

[3]
  On the left of Copae about twelve stades from it is Olmones, and some seven stades distant from Olmones is Hyettus both right from their foundation to the present day have been villages. In my view Hyettus , as well as the Athamantian plain, belongs to the district of Orchomenus . All the stories I heard about Hyettus the Argive and Olmus, the son of Sisyphus, I shall include in my history of Orchomenus . ¹ In Olmones they did not show me anything that was in the least worth seeing, but in Hyettus is a temple of Heracles, from whom the sick may get cures. There is an image not carefully carved, but of unwrought stone after the ancient fashion.

[3] On the left of Copae about twelve stadium-lengths from it is Olmones, and some seven stadium-lengths distant from Olmones is Hyettos both right from their foundation to the present day have been villages. In my view Hyettos, as well as the Athamantian plain, belongs to the district of Orkhomenos. All the stories I heard about Hyettos the Argive and Olmus, the son of Sisyphus, I shall include in my history of Orkhomenos. 580

In Olmones they did not show me anything that was in the least worth seeing, but in Hyettos is a temple of Hēraklēs, from whom the sick may get cures. There is an image not carefully carved, but of unfinished stone after the ancient fashion.
