Cornix is a character in Ovid's Metamorphoses.
There, she recounts how she was a princess, the daughter of Coronaeus. One day as she was walking by the seashore, Neptune saw her and attempted to seduce her. When his efforts failed he attempted rape, and Cornix fled, crying out to men and gods, and while no man heard her, "the virgin goddess feels pity for a virgin": Minerva transformed her into a crow. She also cites her resentment that her place as Minerva's servant is being taken over by Nyctimene transformed into the owl, where the transformation was punitive.
John Gower took up the tale for use in his Confessio Amantis, with particular emphasis on her delight in her escape:
With fetheres blake as eny cole
Out of hise armes in a throwe
Sche flih before his yhe a Crowe;
Which was to hire a more delit,
To kepe hire maidenhede whit
Under the wede of fethers blake,
In Perles whyte than forsake
That no lif mai restore ayein.

Once back at the soothing task of grooming Cornix while he stood, hipshot, eyes closed, enjoying the attention, I quite liked the notion of riding the great stallion all the way to Camelot.
Cornix and the other three stallions were housed in their own barn, with the three pony stallions already standing at the stud.
Cornix was the most unbiddable of the stallions-so wild he had had to be roped, tied, and twitched before a round bit could be inserted between his snapping jaws and a stout bridle attached to his head.
The rain had a dampening effect on Cornix, who plodded along beside Spadix as meek as a sheep.
As usual, Cornix whickered at the sight of me and Spadix added his comments in a shriller tone.
