The representations of Christ as well as those of emperors in Byzantine wall-paintings quite often display a characteristic iconographic symbol on the forehead, between the eyes. At first sight it looks like a wrinkle, however, a more carefull observation reveals that it is a sign, the symbol of the “third eye”, which suggests the spiritual properties of the represented figure.

This iconographic element implies that Byzantine art is not only figurative and symbolic, but that it also offers to the believer the possibility of exalting himself to a high level of self-knowledge, wisdom, fulfilment and knowledge of the universe.
