Tumultuarii
sc. milites. Soldiers sworn in en masse in times of great danger to the State (in tumultu), tumultus being technically an Italic or Gallic war. The form by which these troops were sworn was called coniuratio, and differed from the sacramentum or regular military oath in that persons sworn by it were freed from its obligations as soon as the crisis was over. The first instance of this coniuratio that is recorded was in B.C. 216, in the Second Punic War (Livy, xxii. 38). See Mommsen in the Eph. Epigraph. v. 143; and cf. the articles delectus; sacramentum.
