Capua’s mithraeum is one of the most beautiful and well preserved sanctuaries dedicated to the Indo-Iranian god Mythras. It was discovered at the end of September 1922. It was probably built at the beginning of the second century AD.
All the walls are covered by stucco paintings. The vault is decorated with stars with eight points, painted in red and blue on a yellow background. The back wall is decorated with a fresco, representing the god Mitra in the act of killing a bull, of worthy plastic monumentality emphasized by a perfect use of colours. The young Mythras is portrayed in his coloured oriental costume: under a red Phrygian cap with green and golden borders snip his curly hair and his face is in a frontal position.
