Other analogous or comparable deities of the "prima" in Indo-European religions have been analysed by G. Dumézil. They include the Indian goddess Aditi who is called "two-faced" as she is the one who starts and concludes ceremonies, and Scandinavian god Heimdallr. The theological features of Heimdallr look similar to Janus's: both in space and time he stands at the limits. His abode is at the limits of Earth, at the extremity of Heaven; he is the protector of the gods; his birth is at the beginning of time; he is the forefather of mankind, the generator of classes and the founder of the social order. Nonetheless he is inferior to the sovereign god Oðinn: the "Minor Völuspá" defines his relationship to Oðinn almost with the same terms as those in which Varro defines that of Janus, god of the "prima" to Jupiter, god of the "summa": Heimdallr is born as the "firstborn " ("primigenius", "var einn borinn í árdaga"), Oðinn is born as the "greatest" ("maximus", "var einn borinn öllum meiri"). Analogous Iranian "formulae" are to be found in an Avestic "gāthā" (Gathas). In other towns of ancient Latium the function of presiding over beginnings was probably performed by other deities of feminine sex, notably the "Fortuna Primigenia" of Praeneste.
