Hemchandracharya

Hemachandra was a 12th century (c. 1088  – c. 1172/1173 CE) Indian Jain saint, scholar, poet, mathematician, philosopher, yogi, grammarian, law theorist, historian, lexicographer, rhetorician, logician, and prosodist. Noted as a prodigy by his contemporaries, he gained the title kalikālasarvajña, "the knower of all knowledge in his times" and father of Gujarati language. Born as Changadeva, he was ordained in the Śvētāmbara school of Jainism in 1110 and took the name Somachandra. In 1125 he became an adviser to King Kumarapala and wrote Arhanniti, a work on politics from a Jain perspective. He also produced Trishashti-shalaka-purusha-charita (“Deeds of the 63 Illustrious Men”), a Sanskrit epic poem on the history of important figures of Jainism. Later in his life, he changed his name to Hemachandra.
