Golagrama is a village or region in India associated with several medieval Indian astronomers, astrologers and mathematicians. Presently there is no place bearing the name Golagrama anywhere in India. It is known that Golagrama was situated in Maharashtra State on the northern banks of river Godavari, was near Partha-puri (Pathari)〔 (see p.21)〕 in Maharahstra and was about 320 km away from Amravati town in Maharashtra. It is sometimes identified as a place named ''Golgam'' at latitude 18° N longitude 78° E.〔 (see p.xxvii)〕 The name ''Golagrama'' considered as a word in Sanskrit could literally be translated as ''sphere-village''. ==Golagrama school of astronomy== Several medieval Indian astronomers and mathematicians are known to have flourished in Golagrama. They were all members of one large extended family. The astronomical and mathematical knowledge of the members of this family was passed from generation to generation through teacher-pupil relationships. In nearly all the cases, the teacher would be an elder member of the family like father being a teacher of his son, elder brother being teacher of a younger brother. The members of this family were also referred to as ''Daivajnas''. One of the most distinguished mathematician of this family was Kamalakara. Kamalakara was born in Benares about 1616 after some members of the family migrated to Benares. The lineage of stronomers and astrologers begins with one Rāma, a Maharshtian Brahmin residing at Golagrama.〔〔 (see item 2778 in p.996)〕 Rāma had a son by name Bhaṭṭācārya. He is known to have fathered Divākara Daivjña.〔 Divākara Daivjña had five sons all experts in astrology and astronomy. Divākara Daivjña's sons were Viṣṇu, Kṛṣṇa, Mallāri, Keśava and Viśvanātha. Kṛṣṇa Daivajña had two sons Nṛsiṃha (also known as Nṛsiṃha Gaṇaka) born in 1586, and Śiva. Nṛsiṃha is known to have composed ''Saurabhāṣya'', a commentary on ''Sūrysidhānta''. Nṛsiṃha had composed ''Sidhāntaśromaṇi-Vāsanāvārttika'' a commentary on the ''Gaṇitādhyāya'' and ''Golādhyāya'' of ''Sidhāntaśiromaṇi-Vāsanābhāṣya'' of Bhāskara II.〔 (see items 2857, 2858 in p.1017)〕 Mallari (fl.1575) was a pupil of Ganesa (born 1507). Mallari was also the uncle and teacher of Nrisimha (born 1586). He wrote a commentary on the ''Grahalaghava'' of Ganesa (born 1507) and also another treatise titled ''Parvadvayasadhana''.〔 (see p.386)〕 Keśava had a son by the name Gaṇeśa who had composed in 1520 CE ''Grahalāghava'' or ''Sidhāntarahasya'' a compendium of astronomical calculations.〔 (see items 2931 in p.1041)〕 Nṛsiṃha (born 1586) had four sons Divākara (born 1606), Kamalākara, Gopinātha and Ranganātha. Kamalākara had composed in 1656 CE a treatise titled ''Sidhāntatattvaviveka'' which was course on astronomy founded mainly on ''Sūryasidhānta''.〔 (see items 2890. 2891 in p.1026)〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Golagrama」の詳細全文を読む スポンサード リンク
