Vedanga Jyotisha

Template:Short description Template:Italic title Template:Use dmy dates Template:Use Indian English Vedanga Jyotisha (Template:IAST3), or Jyotishavedanga (), is one of earliest known Indian texts on astrology (Jyotisha). The extant text is dated to the final centuries BCE,Template:Sfn but it may be based on a tradition reaching back to about 700-600 BCE.Template:Sfn

The text is foundational to Jyotisha, one of the six Vedanga disciplines. Its author is traditionally named as Lagadha.Template:Sfn

Textual history

The dating of the Vedanga Jyotisha is relevant for the dating of the Vedic texts.Template:Sfn The Vedanga Jyotisha describes the winter solstice for the period of ca. 1400 BCE. This description has been used to date the Vedanga Jyotisha.Template:Sfn 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".Template:Sfn 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.Template:Sfn 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. The estimation of 1400-1200 BCE has been followed by others,Template:SfnTemplate:Sfn with Subbarayappa adding that the extant form can possibly be from 700-600 BCE.Template:Sfn

Other authors propose a later composition. Santanu Chakraverti writes that it has been composed after 700 BCE,Template:Sfn while Michael Witzel dates it to the last centuries BCE, based on the style of composing.Template:Sfn 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.Template:Sfn This may be due to the incorporation of late Harappan astronomical knowledge into the Vedic fold,Template:Sfn an idea also proposed by Subbarayappa.Template:Sfn Michael Witzel notes: Template:Quote
