In Situ Implementation of Imaging Techniques Reveals Key Motifs in the Early Byzantine Wall Painting of Christ’s Baptism at Shivta, Israel

Abstract

Following the rediscovery of the Early Byzantine wall painting of Christ’s baptism in the northern church of Shivta in southern Israel, the painting was investigated with different imaging techniques in order to clarify the scene and to find additional painted motifs and hidden colors and patterns. Besides high-quality photography from close distance on a scaffolding at 3.5 m height, thus at the level of the painting, Near IR photography (NIR), UV wavelengths microscopy, and Visible Induced Luminescence (VIL) imaging were all conducted in order to collect new information on the painting. The combination of several imaging techniques provided new and surprising details on elements of the painting, especially revealing blue color around the head and shoulders of Christ, most probably reminiscent of the River Jordan where the baptism took place.
