Max Muller's Edition Gives the Rigveda a Scholarly Text

Vedic philology studies the language of the Rigveda and the later Vedic corpus, using internal linguistic evidence, shifts in grammar, vocabulary and meter, to establish that the corpus was composed in distinct layers over a long span rather than delivered as a single unified text at one moment. The German born scholar Friedrich Max Muller produced the corpus's founding critical edition, a six volume edition of the Rigveda with Sayana's traditional commentary published between 1849 and 1873, giving Vedic philology for the first time a complete, textually established base from which later scholars such as Rudolf von Roth built systematic Vedic lexicography and comparative study.

The Vedic corpus is often presented within Hindu tradition as a single, timeless revelation, but Vedic philology's internal linguistic dating shows the Rigveda's hymns, the middle Vedic prose texts and the later Upanishads were composed centuries apart from one another, each layer reflecting a different stage of the language and of religious thought. Where the atlas describes a teaching as belonging to a specific Vedic layer, that dating rests on this philological chronology rather than on the tradition's own presentation of the whole corpus as a single undifferentiated revelation.
