name the ancient text which has discussed the six canons of indian art
Indian painting Around the 1st century BC the Shadanga or Six Limbs of Indian Painting, were evolved, a series of canons laying down the main principles of the art.[2] Vatsyayana, who lived during the third century A.D., enumerates these in his Kamasutra having extracted them from still more ancient works.
Upanishads More than 200 Upanishads are known, of which the first dozen or so are the oldest and most important and are referred to as the principal or main (mukhya) Upanishads.[14][15] The mukhya Upanishads are found mostly in the concluding part of the Brahmanas and Aranyakas[16] and were, for centuries, memorized by each generation and passed down orally. The early Upanishads all predate the Common Era, five[note 6] of them in all likelihood pre-Buddhist (6th century BCE),[17] down to the Maurya period.[18] Of the remainder, 95 Upanishads are part of the Muktika canon, composed from about the last centuries of 1st-millennium BCE through about 15th-century CE.[19][20] New Upanishads, beyond the 108 in the Muktika canon, continued to be composed through the early modern and modern era,[21] though often dealing with subjects which are unconnected to the Vedas.[22]
