Arabic numerals
The first mentions of the numerals in the West are found in the "Codex Vigilanus" of 976.
Old Arabic
Old Arabic is the earliest attested stage of the Arabic language, beginning with the first attestation of personal names in the 9th century BC, and culminating in the codification of Classical Arabic beginning in the 7th century AD. Originally the primary language of the Safaitic and Hismaic inscriptions, it came to be expressed primarily in a modified Nabataean script after the demise of the Nabataean Kingdom. In addition, inscriptions in Old Arabic are attested in the Dadanitic script and the Greek alphabet, the latter of which have proved indispensable in the reconstruction of the language's phonology.
