Akalanka

Akalaṅka [IAST: Akalaṅka] (also known as Akalaṅkadeva and Bhatta Akalaṅka) was a Jain logician whose Sanskrit-language works are seen as landmarks in Indian logic. He lived from 720 to 780 C. E. and belonged to the Digambara sect of Jainism. His work Aṣṭaśatī, a commentary on Āptamīmaṃsa of Ācārya Samantabhadra deals mainly with Jaina logic. He was a contemporary of Rāṣṭrakūta king Krishna I. He is the author of Tattvārtharājavārtika, a commentary on major Jaina text Tattvārtha Sutra. He greatly contributed to the development of the philosophy of Anekāntavāda and is therefore called the "Master of Jain logic".
