chidna, a nymph who dies not nor grows old all her days.

(ll. 306-332) Men say that Typhaon the terrible, outrageous and lawless,
was joined in love to her, the maid with glancing eyes. So she conceived
and brought forth fierce offspring; first she bare Orthus the hound of
Geryones, and then again she bare a second, a monster not to be
overcome and that may not be described, Cerberus who eats raw flesh, the
brazen-voiced hound of Hades, fifty-headed, relentless and strong.
And again she bore a third, the evil-minded Hydra of Lerna, whom the
goddess, white-armed Hera nourished, being angry beyond measure with
the mighty Heracles. And her Heracles, the son of Zeus, of the house of
Amphitryon, together with warlike Iolaus, destroyed with the unpitying
sword through the plans of Athene the spoil-driver. She was the mother
of Chimaera who breathed raging fire, a creature fearful, great,
swift-footed and strong, who had three heads, one of a grim-eyed lion;
in her hinderpart, a dragon; and in her middle, a goat, breathing forth
a fearful blast of blazing fire. Her did Pegasus and noble Bellerophon
slay; but Echidna was subject in love to Orthus and brought forth the
deadly Sphinx which destroyed the Cadmeans, and the Nemean lion, which
Hera, the good wife of Zeus, brought up and made to haunt the hills
of Nemea, a plague to men. There he preyed upon the tribes of her own
people and had power over Tretus of Nemea and Apesas: yet the strength
of stout Heracles overcame him.

(ll. 333-336) And Ceto was joined in love to Phorcys and bare her
youngest, the awful snake who guards the apples all of gold in the
secret places of the dark earth at its great bounds. This is the
offspring of Ceto and Phorcys.

(ll. 334-345) And Tethys bare to Ocean eddying rivers, Nilus, and
Alpheus, and deep-swirling Eridanus, Strymon, and Meander, and the
fair stream of Ister, and Phasis, and Rhesus, and the silver eddies of
Achelous, Nessus, and Rhodius, Haliacmon, and Heptaporus, Granicus,
and Aesepus, and holy Simois, and Peneus, and Hermus, and Caicus fair
stream, and great Sangarius, Ladon, Parthenius, Euenus, Ardescus, and
divine Scamander.

(ll. 346-370) Also she brought forth a holy company of daughters [1615]
who with the lord Apollo and the Rivers have youths in their keeping--to
this charge Zeus appointed them--Peitho, and Admete, and Ianthe, and
Electra, and Doris, and Prymno, and Urania divine in form, Hippo,
Clymene, Rhodea, and Call
