Plutarch, Quaestiones Graecae
Frank Cole Babbitt, Ed.

Eunostus was the son of Elieus, who was the son of Cephisus, and Scias. They relate that he acquired his name because he was brought up by the nymph Eunosta. Handsome and righteous as he was, he was no less virtuous and ascetic. They say that Ochnê, his cousin, one of the daughters of Colonus, became enamoured of him ; but when Eunostus repulsed her advances and, after upbraiding her, departed to accuse her to her brothers, the maiden forestalled him by doing this very thing against him. She incited her brothers, Echemus, Leon, and Bucolus, to kill Eunostus, saying that he had consorted with her by force. They, accordingly, lay in ambush for the young man and slew him. Then Elieus put them in bonds ; but Ochnê repented, and was filled with trepidation and, wishing to free herself from the torments caused by her love, and also feeling pity for her brothers, reported the whole truth to Elieus, and he to Colonus. And when Colonus had given judgement, Ochnê's brothers were banished, and she threw herself from a precipice, as Myrtis,¹ the lyric poetess of Anthedon, has related.

But the shrine and the grove of Eunostus were so strictly guarded against entry and approach by women that, often, when earthquakes or droughts or other signs from heaven occurred, the people of Tanagra were wont to search diligently and to be greatly concerned lest any woman might have approached the place undetected ; and some relate, among them Cleidamus, a man of prominence, that Eunostus met them on his way to the sea to bathe [p. 229] because a woman had set foot within the sacred precinct. And Diocles² also, in his treatise upon the Shrines of Heroes, quotes a decree of the people of Tanagra concerning the matters which Cleidamus reported.
