The Alhambra tilings are periodic; in other words, they consist of some basic unit that is repeated in all directions to fill up the available space. All 17 different groups of isometries – the possible ways of repeatedly tiling the plane – are used at the palace.
The designs left a deep impression on Maurits Escher, who came here in 1936. Subsequently, Escher's art took on a much more mathematical nature and over the next six years he produced 43 colored drawings of periodic tilings with a wide variety of symmetry types.
