Codex Luminara is a small digital gallery built as an old portal: you stand at the centre of a sphere whose inner walls are hung with paintings, the way a collector's cabinet once wrapped its owner in pictures. Drag to wander the walls. Step closer to any work and its folio opens.

The collection follows the long arc of European painting — from the illuminated vellum of the medieval scriptorium, through the oil revolution of the North and the High Renaissance of Florence, Rome and Venice, to the candlelit climax of the Dutch Baroque.
