PROLEGOMENA TO PRAKRITICA et JAINICA
In this age belonged Haribhadra Suri (705-775 A.D.) whose Şad-darśana-samuccaya is a famous book where brief discussions of the different systems of Indian philosophy are described. In fact, as far as I know, Haribhadra Sūri's Anekāntajayapatākā edited by H.R. Kapadia (Baroda 1947) is perhaps the first book where the problem of anekānta philosophy is explained.
In the same period (i.e. in the later part of the 8th century) also belonged Bhatta Akalanka or Akalankadeva who wrote the Tattvārtharājavārttika on the Tattvärthādhigama-sūtra of Umāsvāti, and Aştaśati, a commentary on Samantabhadra's Āpta-mimāṁsā, Nyāyaviniscaya, Tattvārtha-vārttika-vyākhyānālankāra and numerous others.
Two other famous authors also belonged to this golden age. And they are-Vidyānandi (belonging to the early part of the 9th century A.D.) and Māņikyanandi (also belonging to the 9th century A.D.). Vidyānandi (a Digambara) wrote a commentary entitled Astasahasri on the Aştaśati of Akalankadeva and Tattvārtha-ślokavārttika, whereas Māṇinkyanandi (another Digambara of the 9th cent. A.D.), wrote his famous Parikşāmukha on Jain Logic.
In the last period of Jain philosophy (bet. 11th and 15th centuries A.D.), there developed the Jain philosophy on the syādvāda. Two contemporary authors Devasūri (1086-1169 A.D.) and Hemacandra (1088-1172 A.D.)--are the pioneers on the idea of syāduāda. Devasūri wrote pramāņa-naya-tattvālokalaňkāra and its commentary Syāduādaratnākara. The prolific writer Hemacandra has two famous works called Anya-yoga-vyavacchedikādvātrimśika and Pramāņa-mimāṁsā which are the landmarks on Jain philosophical texts.
So also Ratnaprabhasuri and Mallisena. Ratnaprabhasuri (1181 A.D.) wrote Syādvāda-ratnākaravārttika which was a shorter commentary on the Syādvāda-ratnākara.
