A putto is often called a cherub (plural cherubs) although unlike the Biblical cherub (plural cherubim) in form and symbolism: cherubim have four faces of different species and several pairs of wings, and are sacred, whereas putti are secular and represent a non-religious passion.
(The term stallion for an uncastrated male horse dates from this time; stallion = stalled one.) Stallion is also used to refer to males of other equids, including zebras and donkeys.
Humans can increase the chances of conception, a successful pregnancy, and successful foaling. The male parent of a horse, a stallion, is commonly known as the sire and the female parent, the mare, is called the dam. Both are genetically important, as each parent provides 50% of the genetic makeup of the ensuing offspring, called a foal.
