Decima was one of the three Parcae (known in English as the Fates) in Roman mythology. [1] The Parcae goddess Nona was responsible for pregnancy; Decima was responsible for measuring a person's lifespan; and Morta was charged with overseeing death. [2] They distributed to mankind all the good and bad things in life, [3] and according to some classical writings even Jupiter had to bend to their will. [4] Decima measured the thread of life with her rod, [5] like her Greek equivalent Lachesis. [4] In some accounts, her mother was Nox the goddess of night and her father was Scotus the god of darkness; while in other accounts, her parents were Jupiter and Themis. [3]
