Oladevi is an important part of folk tradition in Bengal, and is honoured by communities of different religions and cultures.
[1][2][3] Oladevi is believed to be the wife of Mayasura, the legendary king and architect of Asuras, Danavas, and Daityas in mythology folktales.
To Hindus, Oladevi is the combined form of the Goddess Parvati, portrayed as a lady with deep yellow skin wearing a blue sari and adorned with ornaments.
[2] The worship of Oladevi as the Goddess of Cholera is believed to have emerged in the 19th century CE with the spreading of the disease in the Indian subcontinent.
[1] However, the significance of her worship has diminished in modern times as outbreaks of cholera have been reduced considerably by advancements in medicine and sanitation.
