"Aequitas (genitive aequitatis) is the Latin concept of justice, equality, conformity, symmetry, or fairness. It is the origin of the English word "equity". In ancient Rome, it could refer to either the legal concept of equity, or fairness between individuals.
Cicero defined aequitas as "tripartite": the first, he said, pertained to the gods above (ad superos deos) and is equivalent to pietas, religious obligation; the second, to the Manes, the underworld spirits or spirits of the dead, and was sanctitas, that which is sacred; and the third pertaining to human beings (homines) was iustitia, "justice"." - (en.wikipedia.org 30.01.2020)
