EXTRĂORDĬNĀRĬI

[ Exercitus , p. 167 .] f FABRI are workmen who make anything out of hard materials, as fabri tignarii , carpenters, fabri aerarii , smiths, . The different trades were divided by Numa into nine collegia, which correspond to our companies or guilds. In the constitution of Servius Tullius, the fabri tignarii and the fabri aerarii or ferrari i were formed into two centuries, which were called the centuriae fabrum (not fabrorum ). They did not belong to any of the five cla es into which Servius divided the people; but the fabri tign. probably voted with the first cla , and the fabri aer. with the second. The fabri in the army were under the command of an officer called praefect us fabrûm .
