Pausanias Description of Greece 2.15.2

[2] From Cleonae to Argos are two roads; one is direct and only for active men, the other goes along the pass called Tretus (Pierced), is narrow like the other, being surrounded by mountains, but is nevertheless more suitable for carriages. In these mountains is still shown the cave of the famous lion, and the place Nemea is distant some fifteen stades. In Nemea is a noteworthy temple of Nemean Zeus, but I found that the roof had fallen in and that there was no longer remaining any image. Around the temple is a grove of cypress trees, and here it is, they say, that Opheltes was placed by his nurse in the grass and killed by the serpent.

[2] From Kleonai to Argos are two roads; one is direct and only for men who are physically fit, the other goes along the pass called Trētos, is narrow like the other, being surrounded by mountains, but is nevertheless more suitable for vehicles. In these mountains is still shown the cave of the famous lion, and the place [ khōrion] called Neméā is distant some fifteen stadium-lengths. In Neméā is a temple [ nāos] of Nemean [ Nemeios] Zeus, which is worthy of viewing [ théā], but I found that the roof had caved in and that there was no longer any statue [ agalma] [of Zeus] left. Around the temple is a grove of cypress trees, and here it is, they say, that Opheltes was placed by his nurse in the grass and killed by the serpent [ drakōn].
