Tessera — a clay or wax tablet used to record information in ancient Rome. The wax tablets could be used multiple times. Tesserae were very popular among the Roman military: there are many bas-reliefs depicting them both with single tesserae and with whole sets that they carried in special bags. There was also a special military rank,named after such tablets — tesserary.
Part of a stele to Annaius Daverzus with a tessera,a military man from cohors IIII Delmatarum. Early 1st century ADThe word tessera could denote several small objects carrying written or conventional meaning: a wax tablet, token, password, pass, accounting mark or game piece. In a military context tesserae with orders and passwords were especially important, passed through the chain of command and supervised by the tesserarius.
The spread of tesserae shows that the Roman army and urban life relied on practical literacy. A short note could record property, distribute duties or confirm a right to rations or entry. The tessera therefore links material culture with administration: a small object worked as part of a large management system.
