One hundred and seven of the ostraca are written in the Paleo-Hebrew alphabet and dated to circa 600 BCE. Of the ostraca dated to later periods, the bulk are written in Aramaic and a few in Greek and Arabic.[3]
The majority of the Hebrew ostraca are lists of names and administrative letters to the commanders of the fort; everyday correspondence between military supply masters, requests for supplies, and so on. Most of them are addressed to Eliashib (also transliterated Elyashiv; not to be confused with the biblical high priest Eliashib), thought to be the quartermaster of Arad.[4]
Eighteen ostraca consisting mainly of letters addressed to Eliashib were found in a chamber of the casemate wall of the fort.[5] These are known as the Eliashib Archive.
