or Galerum, diminutive Galericulum (probably allied to galea, helmet), in Roman Antiquity, was originally a head-dress worn by priests, but especially by the flamen dialis. Its shape was probably a round cap formed of leather, with its top terminating in an apex. In later times the galerus was any kind of cap fitting close to the head like a helmet. Galerus, as well as galericulum, also came to signify a periuke, wig, or covering for the head made of hair. Flamen dialis solus album habet galerum. See Albogalerus, vol. ii., p. 449.
