Pausanias Description of Greece 2.3.6

[6] As you go along another road from the market-place, which leads to Sicyon , you can see on the right of the road a temple and bronze image of Apollo, and a little farther on a well called the Well of Glauce. Into this they say she threw herself in the belief that the water would be a cure for the drugs of Medea. Above this well has been built what is called the Odeum (Music Hall), beside which is the tomb of Medea's children. Their names were Mermerus and Pheres, and they are said to have been stoned to death by the Corinthians owing to the gifts which legend says they brought to Glauce.

[6] As you go along another road from the marketplace [ agorā], which leads to Sikyon, you can see on the right of the road a temple [ nāos] of Apollo, which has a bronze statue [ agalma] of him. A little farther along the way is a well called the Spring [ krēnē] of Glauke. Into this well they say she [= Glauke] threw herself, thinking that the water would be a cure for [the pain that she was suffering from] the magical drugs [ pharmaka] of Medea. Above this spring [ krēnē] has been built what is called the Odeum [ ōideion], beside which is the tomb [ mnēma] of Medea’s children. Their names were Mermeros and Pheres, and they are said to have been stoned to death by the Corinthians because—as is also said—they had brought to Glauke the gifts [ dōra] [from Medea].
