A quincunx is a spatial arrangement of five elements, with four elements placed as the corners of a square and the fifth placed in the center. The five peaks of Mount Meru were taken to exhibit this arrangement, and Khmer temples was arranged accordingly in order to convey a symbolic identification with the sacred mountain. The five brick towers of the 10th-century temple known as East Mebon, for example, are arranged in the shape of a quincunx. The quincunx also appears elsewhere in designs of the Angkorian period, as in the riverbed carvings of Kbal Spean.
