The Quilon Syrian Copper Plate (c. 883 AD, "the Tabula Quilonensis") is written in Old Malayalam in Vatteluttu script, and concludes with a number of "signatures" in Kufic Arabic, Middle Persian in Pahlavi script and Judaeo-Persian. The charter shows Atikal, in presence of the royal representative from Kodungallur (prince Kota Ravi Vijayaraga) and regional civil and military officials, granting land and serfs to the Tarisapalli, built by Mar Sapir Iso, and conferring privileges on Anchuvannam and Manigramam. The attestation to the copper plates in the Kufic script reads: "[And witness] to this Maymun ibn Ibrahim, Muhammad ibn Manih, Sulh [?Salih] ibn 'Ali, 'Uthaman ibn al-Marzuban, Muhammad ibn Yahya, 'Amr ibn Ibrahim, Ibrahim ibn al-Tayy, Bakr ibn Mansur, al-Qasim ibn Hamid, Mansur ibn 'Isa and, Isma'il ibn Ya'qub". The presence of non-Christian signatures and the names found in the charter prove that the associates of Mar Sapir Iso included Jews and Muslims too. Muslim Arabs and some Persians must have formed permanent settlements at Kollam by this period. The charter gives proof of the status and privileges of trading guilds in Kerala."Anjuvannam", mentioned in the copper plate, was a merchant association composed Christians, Jews and Muslims.
