Janus is the double-faced god of archways, entrenches, passages, time, the beginning & the end. The Romans named January in his honor & was one of the 12 principal deities of Religio Romana (Roman Religion). Janus was unique to Latium (centeral western Italy), predating the Romans & had no Greek counterpart.
Janus had his ceremonies carried out by the Rex Sacrorum (King of the Sacred) instead of dedicated flamens (priests) like the other deities. The shrine Janus Geminus was dedicated to him which had giant double doors which would be closed in times of peace and left open during times of war. The Roman historian Titus Livius would recount the doors being closed only twice between the time of Numa Pompilius (7th century BC) and Augustus (1st century BC).
For the first time, Legio XXX will be hosting an Agonium near Tillsonburg Ontario (Thank you Tom Ross). It's a private single day event where we try not to freeze. If winter camping isn't your thing, consider coming to Castra Aestiva in May or Castra Hiberna in September.
Come, participate and enjoy the camaraderie only the field of Mars can forge.
