KASTALIA (or Castalia) was the Naiad Nymph of the prophetic springs of the Delphic Oracle on Mount Parnassos, Phokis (central Greece). Her waters were said to be born of either the Aitolian river Akheloos of the Phokian Kephisos, emerging first on the slopes of Mount Parnassos as Kassotis, then sinking into the ground reappeared as the spring Kastalia beside the seat of the Delphic oracle. The nature of these two springs perhaps explains the name, kass-, from kassuô, to sew, the two being so tied together.
She appears to be loosely connected with Daphnis the prophetic Nymphe of pre-Apollion oracle, the Naiades Korykiai of the sacred Corycian cave, and the Nymphe Thyia loved by Apollon.

CASSO′TIS (Kassôtis), a Parnassian nymph, from whom was derived the name of the well Cassotis at Delphi, the water of which gave the priestess the power of prophecy. (Paus. x. 24. § 5.)
CASTA′LIA (Kastalia), the nymph of the Castalian spring at the foot of mount Parnassus. She was regarded as a daughter of Achelous (Paus. x. 8.§ 5), and was believed to have thrown herself into the well when pursued by Apollo. (Lutat. ad Stat. Theb. i. 697.) Others derived the name of the well from one Castalius, who was either a simple mortal, or a son of Apollo and father of Delphis, who came from Crete to Crissa, and there founded the worship of the Delphinian Apollo. (Ilgen, ad Hom. hymn. in Apoll. p. 341.) A third account makes Castalius a son of Delphus and father of Thyia. (Paus. vii. 18. § 6, x. 6. § 2.)

Alcaeus, Fragment 307 (from Himerius, Orations) (trans. Campbell, Vol. Greek Lyric I) (Greek lyric C6th B.C.) :
"Kastalia (Castalia) flows in poetic fashion with waters of silver, and Kephisos (Cephisus) [river of Phokis and Boiotia] rises in flood surging with waves, in imitation of Homer's Enipeus: for Alkaios is compelled just like Homer to give even water the power to sense the presence of gods."
Alcaeus, Fragment 307 (from Strabo, Geography) :
"So in Alkaios the Kastalian (Castalian) spring at Delphoi with its prophetic water is called water of Tritaia [or joy of Tritaia]."
Pausanias, Description of Greece 10. 8. 9 (trans. Jones) (Greek travelogue C2nd A.D.) :
"You reach, on the right of the way [to the sanctuary of Delphoi in Phokis] the water of Kastalia (Castalia), which is sweet to drink and pleasant to bathe in . . . Panyassis [epic poet C5th B.C.] who composed an epic poem on Herakles, says that Kastalia was a daughter of Akheloios (Achelous). For about Herakles he says:--‘Crossing with swift feet snowy Parnassos he reached the immortal water of Kastalia, daughter of Akheloios.’ I have heard another account, that the water was a gift to Kastalia from the river Kephisos (Cephisus). So Alkaios has it in his prelude to Apollon."
Pausanias, Description of Greece 10. 24. 7 :
"You come to a spring called Kassotis (Cassotis) [at Delphoi in Phokis]. By it is a wall of no great size, and the ascent to the spring is through the wall. It is said that the water of this Kassotis sinks under the ground, and inspires the women in the shrine of the god [where it emerges as the spring Kastalia]. She who gave her name to the spring is said to have been a Nymphe of Parnassos."
Nonnus, Dionysiaca 4. 307 ff (trans. Rouse) (Greek epic C5th A.D.) :
"The ridges of Parnassos quaked, when they heard the noise of their neighbour Phoibos (Phoebus) [the oracle of Apollon]; Kastalia (Castalia) marked it, and her inspired water bubbled in oracular rills."
