Nativity scene found beneath 400-year-old painting of beheading

A 16th-century painting of a nativity scene has been discovered beneath another work of art by experts assessing its deterioration.
Outlines of a baby in a manger, angels with haloes, and what appears to be one of the wise men in a stable, were uncovered behind a 400-year-old depiction of the beheading of Saint John the Baptist at The Bowes Museum in County Durham.
