"Apollo everywhere unites and elevates multitude to The One, and uniformly comprehends all the modes of purification; purifying all heaven, generation, and all mundane lives, and separating partial souls from the grossness of matter. Hence the theurgist who is the leader of the Mysteries of this God begins from purifications and sprinklings: "The priest in the first place governing the works of fire, must sprinkle with the cold water of the loud-sounding sea"...as the Oracle says concerning him."
Proklos' commentary to the Cratylus concerning Apollo
