Gezicht op het oratorium van de Sint-Janscokathedraal, achter het altaar 'De onthoofding van Johannes de Doper' van Caravaggio 1855 - 1875

This stereoscopic photograph, taken between 1855 and 1875 by an anonymous artist, captures the interior of the St. John's Co-Cathedral in Valletta, Malta. The image focuses on the ornate altar and the surrounding choir stalls, with the famous Caravaggio painting, "The Beheading of St. John the Baptist," visible in the background. This type of photography, known as stereoscopy, uses two slightly different images to create a three-dimensional effect, offering viewers a more immersive experience of the church's architecture and its art.
