 For example, the Yŏn'ga Buddha is generally accepted to date to 539 because of contemporaneous images from the Metropolitan Museum of Art and the University of Pennsylvania Museum, discussed above, which date to around that time, 524 and 536 respectively.60 years before 539 would be a date too early for the Yon'ga Buddha while a date of 599 (adding sixty years) would make the image archaic and out of style.Baekje sculpture of the 6th century reflect the influence of the native and foreign regimes ruling China during the period of Northern and Southern Dynasties.
