Ver sacrum ("sacred spring") is a religious practice of ancient Italic peoples, especially the Sabelli[1] (or Sabini[2]) and their offshoot Samnites, concerning the dedication of colonies.
It was of special interest to Georges Dumézil, according to whom the ver sacrum perpetuated prehistoric migration practices of Indo-Europeans to the end of the Iron Age and into the beginnings of history, when stable sedentary dwelling conditions had already become general.
As a group, the youth were called sacrani and were supposed to enjoy the protection of Mars until they had reached their destination, expelled the inhabitants or forced them into submission, and founded their own settlement.
[14] Andreas Alföldi[15] has linked each animal with a Roman god, starting with the eagle and Jupiter and ending with the boar of Quirinus: thus the wolf would be related to Mars, the Minotaur to Liber and the horse to Neptune.
[19] In the version accepted as canonic by Livy and Dionysius of Halicarnassus Rome was founded by two twins, sons of Mars, who were nurtured by a she-wolf and who had left the town of Alba of their own accord.
Dumézil's interpretation is not universally shared by scholars: in the Cambridge Ancient History, Arnaldo Momigliano states flatly that "Romulus did not lead a ver sacrum.
