Happy mother's day!

horse simile from Homer's Iliad

'As when some stalled horse who has been corn-fed at the manger breaking free of his rope gallops over the plain in thunder to his accustomed bathing place in a sweet-running river and in the pride of his strength holds high his head and the mane floats over his shoulders; sure of his glorious strength, the quick knees carry him to the loved places and the pasture of horses...'
Iliad 15.263 (trans Lattimore)
