Odissi (Odia: odd'ishii Odisi), also referred to as Orissi in older literature, is a major ancient Indian classical dance that originated in the Hindu temples of Odisha - an eastern coastal state of India. Odissi, in its history, was performed predominantly by women, and expressed religious stories and spiritual ideas, particularly of Vaishnavism (Vishnu as Jagannath). Odissi performances have also expressed ideas of other traditions such as those related to Hindu gods Shiva and Surya, as well as Hindu goddesses (Shaktism). The theoretical foundations of Odissi trace to the ancient Sanskrit text Natya Shastra, its existence in antiquity evidenced by the dance poses in the sculptures of Odissi Hindu temples, and archeological sites related to Hinduism, Buddhism and Jainism.
The Buddhist, Jain and Hindu archaeological sites in Odisha state, particularly the Assia range of hills show inscriptions and carvings of dances that are dated to the 6th to 9th century CE. Important sites include the Ranigumpha in Udaygiri, and various caves and temples at Lalitgiri, Ratnagiri and Alatgiri sites. The Buddhist icons, for example, are depicted as dancing gods and goddesses, with Haruka, Vajravarahi, and Marichi in Odissi-like postures. Historical evidence, states Alexandra Carter, shows that Odissi Maharis (Hindu temple dancers) and dance halls architecture (nata-mandap) were in vogue at least by the 9th century CE. According to Kapila Vatsyayan, the Kalpasutra of Jainism, in its manuscripts discovered in Gujarat, includes classical Indian dance poses - such as the Samapada, the Tribhangi and the Chuaka of Odissi. This, states Vatsyayan, suggests that Odissi was admired or at least well known in distant parts of India, far from Odisha in the medieval era, to be included in the margins of an important Jain text. However, the Jain manuscripts use the dance poses as decorative art in the margins and cover, but do not describe or discuss the dance. Hindu dance texts such as the Abhinaya Chandrika and Abhinaya Darpana provide a detailed description of the movements of the feet, hands, the standing postures, the movement and the dance repertoire. It includes illustrations of the Karanas mentioned in NatyaShastra. Similarly, the illustrated Hindu text on temple architecture from Odisha, the Shilpaprakasha, deals with Odia architecture and sculpture, and includes Odissi postures. Actual sculptures that have survived into the modern era and panel reliefs in Odia temples, dated to be from the 10th to 14th century, show Odissi dance. This is evidenced in Jagannath temple in Puri, as well as other temples of Vaishnavism, Shaivism, Shaktism and Vedic deities such as Surya (Sun) in Odisha. There are several sculptures of dancers and musicians in Konark Sun Temple and Brahmeswara Temple in Bhubaneswar. The composition of the poetic texts by 8th century Shankaracharya and particularly of divine love inspired Gitagovinda by 12th century Jayadeva influenced the focus and growth of modern Odissi. Odissi was performed in the temples by the dancers called Maharis, who played out these spiritual poems and underlying religious plays, after training and perfecting their art of dance starting from an early age, and who were revered as auspicious to religious services. After 12th-century, Odia temples, monasteries and nearby institutions such as the Nalanda in eastern Indian subcontinent came under waves of attacks and ransacking by Muslim armies, a turmoil that impacted all arts and eroded the freedoms previously enjoyed by performance artists. The official records of Sultan Firuz Shah Tughlaq's invasion in Odisha (1360-1361 CE), for example, describe the destruction of the Jagannath temple as well as numerous other temples, defacing of dancing statues, and ruining of dance halls. This led to a broad decline in Odissi and other religious arts, but there were some benevolent rulers in this period who supported arts particularly through performances at courts. During the Sultanate and Mughal era of India, the temple dancers were moved to entertain the Sultan's family and courts. They became associated with concubinage to the nobility. The Odissi dance likely expanded in the 17th century, states Alexandra Carter, under King Ramachandradeva's patronage. This expansion integrated martial arts (akhanda) and athletics into Odissi dance, by engaging boys and youth called Gotipuas, as a means to physically train the young for the military and to resist foreign invasions. According to Ragini Devi, historical evidence suggests that the Gotipuas tradition was known and nurtured in the 14th century, by Raja of Khurda. During the British Raj, the officials of the colonial government ridiculed the temple traditions, while Christian missionaries launched a sustained attack on the moral outrage of sensuousness of Odissi and other Hindu temple dance arts. In 1872, a British civil servant named William Hunter watched a performance at the Jagannath temple in Puri, then wrote, "Indecent ceremonies disgraced the ritual, and dancing girls with rolling eyes put the modest worshipper to the blush...", and then attacked them as idol-worshipping prostitutes who expressed their devotion with "airy gyrations". Christian missionaries launched the "anti-dance movement" in 1892, to ban all such dance forms. The dancers were dehumanized and stigmatized as prostitutes during the British period. In 1910, the British colonial government in India banned temple dancing, and the dance artists were reduced to abject poverty from the lack of any financial support for performance arts, combined with stereotyping stigma. Traditional Odissi repertoire sequence starts with an invocation called Mangalacharana. A shloka (hymn) in praise of a God or Goddess is sung, such as to Jagannath (an avatar of Vishnu), the meaning of which is expressed through dance. Mangalacharan is followed by Pushpanjali (offering of flowers) and Bhumi Pranam (salutation to mother earth). The invocation also includes Trikhandi Pranam or the three-fold salutation - to the Devas (gods), to the Gurus (teachers) and to the Lokas or Rasikas (fellow dancers and audience). The next sequential step in an Odissi performance is Batu, also known as Battu Nrutya or Sthayee Nrutya or Batuka Bhairava. It is a fast pace, pure dance (nritta) performed in the honor of Shiva. There is no song or recitation accompanying this part of the dance, just rhythmic music. This pure dance sequence in Odissi builds up to a Pallavi which is often slow, graceful & lyrical movements of the eyes, neck, torso & feet & slowly builds in a crescendo to climax in a fast tempo at the end. The nritya follows next, and consists of Abhinaya, or an expressional dance which is an enactment of a song or poetry. The dancer(s) communicate the story in a sign language, using mudras (hand gestures), bhavas (enacting mood, emotions), eye and body movement. The dance is fluid, graceful and sensual. Abhinaya in Odissi is performed to verses recited in Sanskrit or Odia language. Most common are Abhinayas on Oriya songs or Sanskrit Ashthapadis or Sanskrit stutis like Dasavatar Stotram (depicting the ten incarnations of Lord Vishnu) or Ardhanari Stotram (half man, half woman form of the divine). Many regionally performed Abhinaya compositions are based on the Radha-Krishna theme. The Astapadis of the Radha-Krishna love poem Gita Govinda written by Jayadeva are usually performed in Odisha, as part of the dance repertoire. The natya part, or dance drama, is next in sequence. Usually Hindu mythologies, epics and legendary dramas are chosen as themes. A distinctive part of the Odissi tradition is the inclusion of Moksha (or Mokshya) finale in the performance sequence. This the concluding item of a recital. Moksha in Hindu traditions means "spiritual liberation". This dance movement traditionally attempts to convey a sense of spiritual release and soul liberation, soaring into the realm of pure aesthetics. Movement and pose merge in a fast pace pure dance climax.
