The Painting of Śākyamuni's Preaching Assembly kept at Wongwangsa Temple features Buddha, and 6bodhisattvas, Gaseop, Anan, 16arhats, and Four Heavenly Kings around Buddha, attempting to partially change the motifs of background depiction, the image support, and emblems. Notably, the depiction of the water surface, which is rarely found in Joseon Śākyamuni's Preaching Assembly paintings, is impressive.
The said work inherited the 18th century tradition of Buddhist paintings produced in the Gyeongbuk region, attempted to partially change the motifs, and heralded the appearance of new-style Buddhist paintings in the 19th century, thereby drawing attention.
A total of 17 people including the head monk painter, Yeongnin, participated in the production of the work. From the comparison of painting styles, the painting style of Yeongsu, rather than that of the head monk painter, is more prominent in the workl; thus the production of the work of Wongwangsa Temple presumably have been led by Yeongsu. Also, the work partially accommodates the painting style of monk painters from the Gyeonggi region in terms of depiction of figures and shades of colors. Exchanges with monk painters in the Gyeonggi region might be possible because the monk painters had worked together in the construction works at Jikjisa Temple or Namjangsa Temple.
The work was estimated to have been produced in the same period that the Vairocana Platform Painting presented in the Birojeon Hall of Beomeosa Temple was. Both works are confirmed to be similar in many aspects such as the provisoin of offerings and the painting style. The great donator, Chigyu, appearing in the work of Wongwangsa Temple, is one of the monks who were engaged in the reconstruction of Beomeosa Hermitage, and his portrait has survived to the present time. From the wording (‘Siam jungchang Daegongdeokju, and Yangseboam) in the portrait, he is believed to have been engaged in the reconstruction of the temple. Notably, From the deleted content (the shrine's name deleted) from the work of Wongwangsa Temple, and the big crosswise length, the work is presumed to have been hung in the hermitage reconstructed by Chigyu.
