The root common to Skt. ṛta, Iran. arta, Lat. ars, artus, ritus, which designates ‘order’ as a harmonious arrangement of the parts of a whole, did not provide any juridical term in Indo-European.
Benveniste establishes that the Indo-European root for ‘order’ is pre-juridical, denoting cosmic harmonic arrangement rather than law — foundational for understanding how order functions in depth-psychological and mythological discourse.
