CRYPTEIA (κρυπτεία), the name of an atrocious practice at Sparta, said to have been introduced by Lycurgus. The following is the description given of the crypteia. The ephors, at intervals, selected from among the young Spartans, those who appeared to be best qualified for the task, and sent them in various directions all over the country, provided with daggers and their necessary food. During the day-time, these young men concealed themselves; but at night they broke forth into the high-roads, and massacred those of the helots whom they met, or whom they thought proper. CŬBĬCŬLĀRĬI, slaves who had the care of the sleeping and dwelling rooms. Faithful slaves were always selected for this office, as they had, to a certain extent, the care of their master’s person. It was the duty of the cubicularii to introduce visitors to their master. CŬBĬCŬLUM usually means a sleeping and dwelling room in a Roman house [DOMUS], but it is also applied to the pavilion or tent in which the Roman emperors were accustomed to witness the public games. It appears to have been so called, because the emperors were accustomed to recline in the cubicula, instead of sitting, as was anciently the practice, in a sella curulis. CŬBĬTUS (πῆχυς), a Greek and Roman measure of length, originally the length of the human arm from the elbow to the wrist, or to the knuckle of the middle finger. It was equal to a foot and a half, which gives 1 foot 5·4744 inches Eng. for the Roman, and 1 foot 6·2016 inches for the Greek cubit. CŬCULLUS, a cowl. As the cowl was intended to be used in the open air, and to be drawn over the head to protect it from the injuries of the weather, instead of a hat or cap, it was attached only to garments of the coarsest kind. The cucullus was also used by persons in the higher circles of society, when they wished to go abroad without being known. CŪDO or CŪDON, a skull-cap made of leather or of the rough shaggy fur of any wild animal, such as were worn by the _velites_ of the Roman armies, and apparently synonymous with _galerus_ or _galericulus_. CŪLĔUS, or CULLĔUS, a Roman measure, which was used for estimating the produce of vineyards. It was the largest liquid measure used by the Romans, containing 20 amphorae, or 118 gallons, 7·546 pints. CŬLĪNA. [DOMUS, p. 143.] [Illustration: Cultri (From Tombstone of a Cultrarius.)] CULTER (μάχαιρα, κοπίς, or σφαγίς), a knife with only one edge, which formed a straight line. The blade was pointed, and its back curved. It was used for a variety of purposes, but chiefly for killing animals either in the slaughter-house, or in hunting, or at the altars of the gods. The priest who conducted a sacrifice never killed the victim himself; but one of his ministri, appointed for that purpose, who was called either by the general name _minister_, or the more specific _popa_ or _cultrarius_. CULTRĀRĬUS. [CULTER.]
