Tromp l'oeil (i.e. trick the eye)
Andrea Mantegna, Camera degli Sposi, Mantua, fresco, 1471-74
This might be one of the most famous examples of tromp l'oeil in the Renaissance (Tromp l'oeil was a favorite Renaissance style -they were really into capturing challenging perspectives back then). Don't be fooled; this ceiling is actually flat.

Some things just don't go out of style, and tromp l'oeil is something that has successfully thrilled viewers for centuries. There's a whole sub-genre of paintings that are meant to look like other art and paper forms, like the painting above. I find I have to remind myself that this is in fact a painting of a sketch tacked to a wooden board, and not a real sketch tacked to a wooden board.
After the invention of the camera in the 1839 and the beginning of its widespread popularity in the second half of the nineteenth century, theorists predicted an end to ultra-realistic types of paintings, realism in paintings had been usurped by photography. Luckily, this was not the case, and there was a revival, (and updating) of tromp l'oeil in the art movement photorealism that began in the 1970s.
