The compiler of the Yoga sūtras, a text on Yoga theory and practice,and a notable scholar of Samkhya school of Hindu philosophy. He is variously estimated to have lived between 5th century BCE to 4th century CE, with more scholars accepting dates between 2nd and 4th century CE.

PATANJALI YOGA SUTRA
The Yoga Sūtras of Patañjali are 196 Indian sutras (aphorisms) on Yoga. It was the most translated ancient Indian text in the medieval era, having been translated into about forty Indian languages and two non-Indian languages: Old Javanese and Arabic.The text fell into obscurity for nearly 700 years from the 12th to 19th century, and made a comeback in late 19th century due to the efforts of Swami Vivekananda and others. It gained prominence again as a comeback classic in the 20th century.
Before the 20th century, history indicates the Indian yoga scene was dominated by other Yoga texts such as the Bhagavad Gita, Yoga Vasistha and Yoga Yajnavalkya. Scholars consider the Yoga Sūtras of Patañjali formulations as one of the foundations of classical Yoga philosophy of Hinduism.
