Alemona is the Roman Goddess who protects the unborn child in its mother's womb. One of many Roman Goddesses concerned with pregnancy and childbirth, Alemona is similar to two of the Parcae—the Roman Pregnancy Goddesses loosely equated with the Fates—called Nona and Decima, who watch over the ninth and tenth months of gestation, respectively. We, of course, would call them the eighth and ninth months of pregnancy, but then we don't count inclusively* like the Romans did. Alemona most likely derives Her name from the Latin verb ale, which means "to nourish, rear, nurse or suckle", as well as "to support or maintain". Tertullian, a 2nd century Roman who was born Pagan but converted to Christianity in midlife, and who (incidentally) vigorously fought against the ridiculous accusations and prejudices levelled at Christians of the time, says Alemona was believed "to nourish the foetus in the womb".

From the same Latin root we get our words aliment, meaning "food"; alimental, "nourishing", and alimony, which is properly money paid to a wife by her estranged husband to provide for the nourishment of their children.

Alemona is often named with Lucina, a childbirth Goddess and sometimes aspect of Juno who brings the baby into the world of light, and Partula, who aids in the heavy labor of giving birth.

*For example, when we want to figure out how many days there are from the 12th of the month to the 17th, we subtract 12 from 17 and get five days. The Romans, however, would count it like this: the 12th, the 13th, the 14th, the 15th, the 16th and the 17th, to get a total of six days.
