Vedāṅga Jyotiṣa, or Jyotiṣavedāṅga (Devanagari: वेदाङ्ग ज्योतिष) (VJ), is one of earliest known Indian texts on astronomy (Jyotisha).[1] The extant text's ideas are dated variedly between final centuries BCE and 14th century BCE (see below) [2] but it may have borrowed from earlier Harappan tradition.[3]

The text is foundational to Jyotisha (astronomy), one of the six Vedanga disciplines.[4] Its author is traditionally named as Lagadha.[5][6][7]

Textual history[edit]

The dating of the Vedanga Jyotisha is relevant for the dating of the Vedic texts.[8][9] The Vedanga Jyotisha describes the winter solstice for the period of ca. 1400 BCE. This description has been used to date the Vedanga Jyotisha.[8] According to Michael Witzel, the question is "whether the description as given in the Jyotisha is also the date of the text in which it is transmitted. It is written in two recensions – Rigveda recensions and Yajurveda recensions. Rigveda recensions and Yajurveda recensions have same verses except for eight additional verses in the Yajurveda's one".[8] T. K. S. Sastry and R. Kochhar suppose that the Vedanga Jyotisha was written in the period that it describes, and therefore propose an early date, between 1370 and 1150 BCE.[8] David Pingree dates the described solstice as about 1180 BCE, but notes that the relevance of this computation to the date of the Vedanga Jyotisha is not evident.[10] The estimation of 1400-1200 BCE has been followed by others,[11][12] with Subbarayappa adding that the extant form can possibly be from 700-600 BCE.[12]

Other authors propose a later composition. Santanu Chakraverti writes that it has been composed after 700 BCE,[7] while Michael Witzel dates it to the last centuries BCE, based on the style of composing.[8] According to Chakraverti, its description of the winter solstice is correct for ca. 1400 BCE, but not for the time of its composition after 700 BCE.[7] This may be due to the incorporation of late Harappan astronomical knowledge into the Vedic fold,[7] an idea which is also proposed by Subbarayappa.[13] Michael Witzel notes:

[O]nly if one is convinced that Lagadha intended the solstice to be exactly at alpha Delphini of Dhanishta, one can date his observations back to the late second millennium. Since that cannot be shown beyond doubt, since the composition of the text is in Late Epic language, and since its contents have clear resemblances to Babylonian works, the text must belong to a late period, to the last centuries BCE.[8]

Subhash Kak disputes the late chronology for the text and argues that it belongs to the second millennium BCE, which is consistent with its internal date. He argues that astronomy in India goes back to an earlier time than is taken by the votaries of the later date[14] and, therefore, the internal date should not be set aside.
