THE KORYKIAI (or Corycidae) were Naiad nymphs of the Korkykian (Corycian) cave of Mount Parnassos near Delphoi in Phokis (central Greece). They originally inhabited the island of Keos (Ceos), but fled to Parnassos after being driven out of the island by a lion.
CORY′CIA (Kôrukia or Kôrukis), a nymph, who became by Apollo the mother of Lycorus or Lycoreus, and from whom the Corycian cave in mount Parnassus was believed to have derived its name. (Paus. x. 6. § 2, 32. § 2.) The plural, Coryciae, is applied to the daughters of Pleistus. (Apollon. Rhod. ii. 710; Ov. Met. i. 320, Heroid. xx. 221.)

Aeschylus, Eumenides 20 ff (trans. Weir Smyth) (Greek tragedy C5th B.C.) :
"[The Pythia, prophetess of the oracle at Delphoi, speaks:] These are the gods I place in the beginning of my prayer [Gaia, Themis, Phoibe and Apollon] . . . and I worship [also] the Nymphai where the Korykian (Corycian) rock is hollow, the delight of birds and haunt of gods. Bromios [Dionysos] has held the region--I do not forget him . . . I call on the streams of Pleistos and the strength of Poseidon, and highest Zeus."
Apollonius Rhodius, Argonautica 2. 710 ff (trans. Rieu) (Greek epic C3rd B.C.) :
"And he [Orpheus] sang to them [the Argonauts] of the daughters of Pleistos, the Korykian Nymphai (Corycian Nymphs), who had encouraged the god [Apollon in his battle against the monster Python] by their repeated cry of ‘Healer’. ‘That,’ he told them, ‘is the origin of the beautiful refrain with which you have been hymning Phoibos.’"
Callimachus, Aetia Fragment 3. 1 (from Oxyrhynchus Papyri 7) (trans. Trypanis) (Greek poet C3rd B.C.) :
"This we heard from old Xenomedes, who once enshrined all the island [the island of Keos (Ceos)] in a mythological history: beginning with the tale of how it was inhabited by the Nymphai Korykiai (Corycian Nymphs) whom a great lion drave from Parnassos: wherefore also they called it Hydrussa . . . Keos, son of Phoibos [Apollon] and Melia, caused it [Hydrussa] to take another name [Keos]."
Strabo, Geography 9. 3. 1 (trans. Jones) (Greek geographer C1st B.C. to C1st A.D.) :
"The whole of Parnassos [mountain in Phokis] is esteemed as sacred [to Apollon], since it has caves and other places that are held in honor and deemed holy. Of these the best known and most beautiful is Korykion (Corycian), a cave of the Nymphai bearing the same name as that in Kilikia [in Asia Minor]."
Pausanias, Description of Greece 10. 32. 7 (trans. Jones) (Greek travelogue C2nd A.D.) :
"The Korykion (Corycian)cave exceeds in size those I have mentioned, and it is possible to make one’s way through the greater part of it even without lights. The roof stands at a sufficient height from the floor, and water, rising in part from springs but still more dripping from the roof, has made clearly visible the marks of drops on the floor throughout the cave. The dwellers around Parnassos believe it to be sacred to the Nymphai Korkykiai, and especially to Pan."
Pausanias, Description of Greece 10. 6. 1 :
"They say that the oldest city was founded here [at Delphoi] by Parnassus, a son of Kleodora, a Nymphe [probaly one of the Korykiai]. Like the other heroes, as they are called, he had two fathers; one they say was the god Poseidon, the human father being Kleopompos. After this Parnassos were named, they say, both the mountain and also the Parnassian glen. Augury from flying birds was, it is said, a discovery of Parnassos. Now this city, so the story goes on, was flooded by the rains that fell in the time of Deukalion. Such of the inhabitants as were able to escape the storm were led by the howls of wolves to safety on the top of Parnassos, being led on their way by these beasts, and on this account they called the city that they founded Lykoreia (Mountainwolf-city).
Another and different legend is current that Apollon had a son Lykoros by a Nymphe, Korykia, and that after Lykoros was named the city Lykoreia, and after the Nymphe the Korykian cave. It is also said that Kelaino was daughter to Hyamos, son of Lykoros, and that Delphos, from whom comes the present name of the city, was a son of Kelaino, daughter of Hyamos, by Apollon.
Others maintain that Kastalios (of the Kastalian spring), an aboriginal, had a daughter Thyia, who was the first to be priestess of Dionysos and celebrate orgies in honor of the god. It is said that later on men called after her Thyiades all women who rave in honor of Dionysos. At any rate they hold that Delphos was a son of Apollon and Thyia. Others say that his mother was Melaina [probably another Korykian Nymphe], daughter of Kephisos (Cephisus)."
Ovid, Metamorphoses 1. 318 ff (trans. Melville) (Roman epic C1st B.C. to C1st A.D.) :
"There a great mountain aims towards the stars its double peak, Parnasus, soaring high above the clouds; and there [during the Great Deluge that destroyed mankind] Deucalion, borne on a raft, with his dear wife [Pyrrha] beside, had grounded; all elsewhere the deluge whelmed. Praise and thanksgiving to the Mountain gods (Numina montis) and the Nymphae Corycidae they gave, and to the prophetess, Themis, then guardian of the oracle."
Ovid, Heroides 20. 221 ff (trans. Showerman) (Roman poetry C1st B.C. to C1st A.D.) :
"An isle once thronged by he Corycian nymphae is girdled by the Aegean sea; its name is Cea."
