For the cooling of Cuchulain's battle-frenzy with water compare the similar treatment in the account of his first foray (L.U., 63a; Miss Faraday's translation, p. 34).
For a literal translation of Faud's triumph song over Cuchulain's return see Thurneysen's translation on page 97 Of the work already referred to. Thurneysen's translation is very close; perhaps the last verse should run: "Long rain of red blood at the side of the trees, a token of this proud and masterful, high with wailing is the sorrow for his fiend-like frenzy."
The description of Cuchulain's appearance in verses 5 and 6 seems to point to a conception of him as the sun-god. Compare the "sunlike" seat of his chariot on page 79.
