# Gargiya-jyotisha

Gargiya-jyotisha (IAST: Gārgīya-jyotiṣa), also known as Garga-samhita (IAST: Garga-saṃhitā), is a 1st-century Indian Sanskrit-language astrological treatise attributed to Garga. The oldest extant text of the Indian astrology (jyotiḥśāstra), it is written in form of a dialogue between Garga and Kraushtuki.

## Date

Gargiya-jyotisha is the oldest extant text of the Indian astrology (jyotiḥśāstra), composed around 25 CE.
Mahabharata 13.18.25–26 (Anushasana Parva) refers to the 64 divisions of a work of Garga, a description identical to given in the second chapter of the Garga-jyotisha. This suggests that the work was well-known and widely circulated by the time this portion of Mahabharata was written.

## Manuscripts and translations

The name Gargiya-jyotisha ("Jyotisha of Garga") derives from the colophons contained in the text's manuscripts. Mitra-mishra's Viramitrodaya refers to the text as Garga-samhita, a name shared by other texts. Other names for the text include Vṛddha-Garga-saṃhitā and Vṛddha-Gārgīyā-jyotiṣa-saṃhitā.
The text is available from several manuscripts, now at Asiatic Society (Kolkata), Sampurnanand Sanskrit Vishwavidyalaya, National Library of India, Bhandarkar Oriental Research Institute, Gangajala Vidyapeeth (Aliyavada), Trinity College (Cambridge), Banaras Hindu University, Mumbai University, Bibliothèque nationale de France, and Rajasthan Oriental Research Institute (Alwar).
