The present article is the result of an ongoing research project and aims to draw attention to simulated azulejo frames. On the one hand, these decorative elements isolate the compositions, closing them in on themselves. On the other hand, simulated azulejo frames help integrate with the tile decoration they are part of, which in turn is part of a global decorative system in line with the concept of artistic totality typical of the Baroque period. This article will examine the various solutions that resort to this kind of frame, known as canvas-frame, including decorative elements, plastic compositions and their effects or consequences for the overall decorations. Finally, the focus will turn to future research directions, based on the systematic cataloguing of the known examples.
