In Hinduism, Hattanath (Bengali: à ¦¹à ¦Âà §Âà ¦Âà ¦¨à ¦¾à ¦¥ hôá¹Âá¹Âônath; Devanagari: à ¤¹à ¤Âà ¥Âà ¤Âà ¤¨à ¤¾à ¤¥ haá¹Âá¹ÂanÃÂtha), who is also known as Hatkeshwar (Bengali: à ¦¹à ¦¾à ¦Âà ¦Âà §Âà ¦¶à §Âà ¦¬à ¦° haá¹Âkeà Âà Âôr; Devanagari: à ¤¹à ¤¾à ¤Âà ¤Âà ¥Âà ¤¶à ¥Âà ¤µà ¤° hÃÂá¹Âkeà Âvara) or Bateshwar (Bengali: à ¦¬à ¦Âà §Âà ¦¶à §Âà ¦¬à ¦° bôá¹Âeà Âà Âôr; Devanagari: à ¤µà ¤Âà ¥Âà ¤¶à ¥Âà ¤µà ¤° vaá¹Âeà Âvara), is the tutelary deity of the city of Sylhet (à Ârëhaá¹Âá¹Âa) in present-day Bangladesh. He is a form of Shiva.
According to Partha Sarathi Nath, Sylhet and the Barak Valley were ruled by the NÃÂtha dynasty of nearby Tripura between the twelfth and thirteenth centuries, which promoted the early settlement of NÃÂthas and their cultural influence in this region. Among these influences is the patronage of à Ârëhaá¹Âá¹ÂanÃÂtha as the titular deity, from which the city of Sylhet (à Ârëhaá¹Âá¹Âa) ultimately takes its name. The NÃÂthas are considered to be the founders of the à Ârëhaá¹Âá¹Âa janapada and were responsible for establishing à Ârëhaá¹Âá¹ÂanÃÂtha idols across the region. The ruins of a à Ârëhaá¹Âá¹ÂanÃÂtha temple are preserved in the headquarters of the Central Muslim Literary Society in Sylhet's Dargah Gate, near the hill of Mona Rai (Monarayer Tila). A Shiva temple known as à Ârëhaá¹Âá¹ÂanÃÂtha from the reign of Isana Deva has been discovered. Mujibur Rahman Chowdhury mentions that the hill was formerly home to an akhara for NÃÂtha Yogi Sannyasis.
Other researchers considered Sylhet's titular deity of Hattanath to have been introduced by the Nagar Brahmin who worshipped HÃÂá¹Âkeà Âvara and its presence in Sylhet (à Ârëhaá¹Âá¹Âa) is mentioned in the Mahalingarchana Tantra. The Nagar Brahmins later settled down in Gujarat, which can be supposed from Padmanath Bhattacharya's analysis. Both Hattanath and its alias Hatkeshwar are considered to be idols of Shiva, and they can be found in various parts of the Sylhet District such as in Bhatera, Panchakhanda, Gotatikar and Chutkhal.
In the 18th-century, Ganesh Ram Shiromani compiled a series of semi-legendary Bengali ballads which claim to detail the early history of Sylhet. Though the book does not hold much authenticity, it is popularly known as the Panchali of Haá¹Âá¹ÂanÃÂth, and mention of Sylhet's final Hindu king Gour Govinda worshipping Haá¹Âá¹ÂanÃÂth after returning to Sylhet can be found. Govinda's predecessors were also known to have held convocations to worship Haá¹Âá¹ÂanÃÂth. A particularly notable one was held in Brahmachal to rectify those who had deviated from the path of Haá¹Âá¹ÂanÃÂth.
