The eight persons thus selected decided by lot in which watch they should make their rounds, two being assigned to each watch. They then repaired to the tribune, and each individual received a written order specifying the posts which he was to visit, every post being visited in each watch by one or other of the two to whom the watch belonged. Sometimes we find centurions, tribunes, and even the general in chief represented as going the rounds, but, under ordinary circumstances, the duty was performed as we have described. The watchword for the night was not communicated verbally, but by means of a small rectangular tablet of wood (πλατεῖον ἐπιγεγραμμένον--_tessera_) upon which it was written.--_Breaking up a Camp._ On the first signal being given by the trumpet, the tents were all struck and the baggage packed, the tents of the general and the tribunes being disposed of before the others were touched. At the second signal the baggage was placed upon the beasts of burden; at the third, the whole army began to move. CĂTĂLŎGUS (κατάλογος), the catalogue of those persons in Athens who were liable to regular military service. At Athens, those persons alone who possessed a certain amount of property were allowed to serve in the regular infantry, whilst the lowest class, the thetes, had not this privilege. [CENSUS.] Thus the former are called οἱ ἐκ καταλόγου στρατεύοντες, and the latter οἱ ἔξω τοῦ καταλόγου. CĂTĂPHRACTA. [LORICA.] CĂTĂPHRACTI (κατάφρακτοι). (1) Heavy-armed cavalry, the horses of which were also covered with defensive armour. Among many of the Eastern nations, who placed their chief dependence upon their cavalry, we find horses protected in this manner; but among the Romans we do not read of any troops of this description till the later times of the empire, when the discipline of the legions was destroyed, and the chief dependence began to be placed on the cavalry. This species of troops was common among the Persians from the earliest times, from whom it was adopted by their Macedonian conquerors. They were called by the Persians _clibanarii_.--(2) Decked vessels, in opposition to _Aphracti_. CĂTĂPĪRĀTĒR (καταπειρατηρία, βολίς), the lead used in sounding (ἐν τῷ βολίζειν), or fathoming the depth of water in navigation. The mode of employing this instrument appears to have been precisely the same as that now in use. CĂTĂPULTA. [TORMENTUM.] CĂTĂRACTA (καταῤῥάκτης), a portcullis, so called because it fell with great force and a loud noise. It was an additional defence, suspended by iron rings and ropes, before the gates of a city, in such a manner that, when the enemy had come up to the gates, the portcullis might be let down so as to shut them in, and to enable the besieged to assail them from above. CĂTEIA, a missile used in war by the Germans, Gauls, and some of the Italian nations, supposed to resemble the ACLIS.
