Phra Buddha Jinaraja
Phra Phuttha Chinnarat is enshrined in the western vihāra of Wat Phra Si Rattana Mahathat Woramahawihan in Phitsanulok province, Thailand. It is believed to have been cast around 1357 CE during the reign of Mahathammaracha I, King of Sukhothai, together with the images Phra Phuttha Chinnasri, Phra Srisattha and Phra Lue. Phra Phuttha Chinnarat is widely regarded as one of the most beautiful Buddha images in Thailand and is among the most frequently reproduced and most revered images in the country.
History
No definitive record exists of its creation. The Northern Chronicle, compiled in 1807 CE, attributes its construction to King Si Thammasok of Chiang Saen along with the founding of Phitsanulok and the casting of the Chinnasri and Srisattha images.In 1866, King Mongkut composed a treatise on the Chinnarat, Chinnasri, and Srisattha based on the Northern Chronicle, giving casting dates of B.E. 1498 for Chinnasri and Srisattha and B.E. 1500 for Chinnarat.
In 1880, during the reign of King Chulalongkorn, Prince-Patriarch Paramanuchitchinorot wrote another version connecting the image to the Chakri dynasty.
Prince Damrong Rajanubhab compared artistic evidence and concluded the image was created in the Sukhothai period because its style combines Sukhothai and Chiang Saen elements. He identified the “King Si Thammasok” of the chronicle as Mahathammaracha Lithai, placing the date around B.E. 1900.
Some scholars, such as Pichaya Sumchinda, have proposed a late Ayutthaya date based on the shrine's decorative motifs, but the prevailing view follows Prince Damrong.
The guardian figures and the ornate ruean kaew shrine are thought to be later Ayutthaya additions. The urna on the forehead was also likely added during that period.
