Grey Mare
.The Grey Mare is the better horse. The woman is paramount. It is said that a man wished to buy a horse, but his wife took a fancy to a grey mare, and so pertinaciously insisted that the grey mare was the better horse, that the man was obliged to yield the point.
⁂ Macaulay says: “I suspect [the proverb] originated in the preference generally given to the grey mares of Flanders over the finest coach-horses of England.”
