In Greek mythology, the mountain was celebrated by Hesiod because two springs sacred to the Muses were located here: the Aganippe and the Hippocrene, both of which bear "horse" (ἵππος hippos) in their toponym. In a related myth, the Hippocrene spring was created when the winged horse Pegasus aimed his hoof at a rock, striking it with such force that the spring burst from the spot. On Helicon too was the spring where Narcissus was inspired by his own beauty.
In Greek myth, Helicon was sacred especially to the divinely inspiring Muses; in his Aitia, Callimachus recounts his dream in which he was young once more and conversed with the Muses on Helicon. There had been a temple built on Helicon in their honor which contained statues of these Muses.
The Hippocrene spring was considered to be a source of poetic inspiration. In the late seventh century BCE, the poet Hesiod sang how in his youth he had pastured his sheep on the slopes of Helicon where Eros and the Muses already had sanctuaries and a dancing-ground near the summit, where "their pounding feet awaken desire". There the Muses inspired him and he began to sing of the origins of the gods. Thus Helicon became an emblem of poetical inspiration. Callimachus explicitly follows in the footsteps of Hesiod and he placed on Helicon the episode in which Tiresias stumbles upon Athena bathing and is blinded but given the art of prophecy.
In Hesiod's Theogony Helicon was mentioned:
The cult centers on Helicon established in a fertile valley near Thespiai and Ascra, under the influence of the Hesiodic texts, in Hellenistic times if not before, were visited by Pausanias in the second century CE. He explored the sacred grove by the spring Aganippe thoroughly and left a full description as it then was. He saw images of Eupheme, nurse of the Muses, and of the legendary poet Linus "in a small rock which has been worked into the manner of a cave". In the temenos were statues, some by famous masters, of Apollo and Dionysus and famed poets. The absence of Homer at Helicon has been noticed by Richard Hunter (Hunter 2006:18f): "The presence of Homer would spoil the party, for the tendency to see these as rival figures for supremacy in epos is familiar from the Contest of Homer and Hesiod, parts of which derive from the classical period". The tripod which Hesiod won at a contest in Chalcis in Euboea was still on view at Helicon in Pausanias' day: the presence of Homer at the festival Hesiod mentions in Works and Days (650-59) was a later interpolation.
