Onam is a major festival of Kerala based on the same mythology, but observed in August-September. In the contemporary era, it commemorates Mahabali. Celebrations include a vegetarian feast, gift giving, parades featuring Bali and Vishnu avataras, floor decorations and community sports. According to A.M. Kurup, the history of Onam festival as evidenced by literature and inscriptions found in Kerala suggest Onam was a temple-based community festival celebrated over a period. The festivities of Onam are found in Maturaikkāñci - a Sangam era Tamil poem, which mentions the festival being celebrated in Madurai temples with games and duels in temple premises, oblations being sent to the temples, people wore new clothes and feasted. The 9th-century Pathikas and Pallads by Periyazharwar, according to Kurup, describes Onam celebrations and offerings to Vishnu, mentions feasts and community events. Several inscriptions from 11th and 12th-century in Hindu temples such as the Thrikkakara Temple (Kochi, dedicated to Vamana) and the Sreevallabha Temple (Tiruvalla, dedicated to Vishnu) attest to offerings dedicated to Vamana on Onam. In contemporary Kerala, the festival is observed by both Hindus and non-Hindus, with the exception of Muslims among whom isolated celebration is observed.
