In ancient Roman religion and myth, the Parcae (singular, Parca) were the female personifications of destiny who directed the lives (and deaths) of humans and gods. They are often called the Fates in English, and their Greek equivalent were the Moirai.
Names and history
The names of the three Parcae are:
- Nona (Greek equivalent Clotho), who spun the thread of life from her distaff onto her spindle;
- Decima (Greek Lachesis), who measured the thread of life with her rod;
- Morta (Greek Atropos), who cut the thread of life and chose the manner of a person's death.
Neuna fata, Neuna dono, Parca Maurtia dono
The names of two of the three Roman Parcae are recorded (Neuna = Nona, Maurtia = Morta) and connected to the concept of fata.
Nona was supposed to determine a person's lifespan on the dies lustricus, that is, the day on which the name of the child was chosen, which occurred on the ninth day from birth for a male and the eighth for a female.
The recurrence of the nundinae was also considered a dies festus and as such nefas by some Roman scholars as Julius Caesar and Cornelius Labeo, because on it the flaminica dialis offered the sacrifice of a goat to Jupiter in the Regia.
In mythology the Parcae were located on a higher hierarchical level than the highest gods :
"The power of the Parcae was great and extend. Some suppose that they were subjected to none of the gods but Jupiter; while others support that even Jupiter himself was obedient to their commands; and indeed we see the father of the gods, in Homer's Iliad, unwilling to see Patroclus perish, yet obliged, by the superior power of the Fates, to abandon him to his destiny" 
"So that we have the clearest evidence of the poet for it, that whatever happens to us is under the influence of the Parcae. Jupiter himself can not interfere to save his son Sarpedon."
