Inscriptional Pahlavi is the earliest attested form of Pahlavi scripts, and is evident in clay fragments that have been dated to the reign of Mithridates I (r. 171âÂÂ138 BC). Other early evidence includes the Pahlavi inscriptions of Parthian coins and the rock inscriptions of Sasanian emperors and other notables, such as Kartir the High Priest.
Inscriptional Pahlavi used 19 non-joining letters written from right to left, and usually with spaces between words:
Inscriptional Pahlavi had its own numerals:
Numerals are written right-to-left, the rightmost being the highestâÂÂwith the exception of multiplication. Numerals add when the one to the left is lower or equal but multiply when it is larger.
Example: 6798 is written as ((3 + 3) ÃÂ 1000 + (4 + 3) ÃÂ 100 + 20 + 20 + 20 + 20 +10 + 4 + 4).
Inscriptional Pahlavi script was added to the Unicode Standard in October, 2009 with the release of version 5.2.
