Lozenge (shape)
A lozenge (/ˈlɒzɪndʒ/ LOZ-inj; symbol: ◊), often referred to as a diamond, is a form of rhombus. The definition of lozenge is not strictly fixed, and the word is sometimes used simply as a synonym (from Old French losenge) for rhombus. Most often, though, lozenge refers specifically to a thin rhombus, especially one with two acute angles of 45° and two obtuse angles of 135°.
The lozenge shape is often used in parquetry (with acute angles that are 360°/n with n being an integer higher than 4, because they can be used to form a set of tiles of the same shape and size, reusable to cover the plane in various geometric patterns as the result of a tiling process called tessellation in mathematics) and as decoration on ceramics, silverware and textiles. It also features in heraldry and playing cards.
The lozenge motif dates from the Neolithic and Paleolithic period in Eastern Europe and represents a sown field and female fertility. The ancient lozenge pattern often shows up in Diamond vault architecture, in traditional dress patterns of Slavic peoples, and in traditional Ukrainian embroidery. The lozenge pattern also appears extensively in Celtic art, art from the Ottoman Empire, and ancient Phrygian art.
The lozenge symbolism is one of the main symbols for women in Berber carpets. Common Berber jewelry from the Aurès Mountains or Kabylie in Algeria also uses this pattern as a female fertility sign.
In 1658, the English philosopher Sir Thomas Browne published The Garden of Cyrus, subtitled The Quincunciall Lozenge, or Network Plantations of the Ancients, in which he outlined the mystical interconnection of art, nature and the universe via the quincunx pattern. He also suggested therein that ancient plantations were laid out in a lozenge pattern.
Lozenges appear as symbols in ancient classic element systems, in amulets, and in religious symbolism. In playing cards, the symbol for the suit of diamonds is a lozenge.
On equipment, especially calculators, the lozenge is used to mark the subtotal key. It is standardized in ISO 7000 as symbol ISO-7000-0650 ("Subtotal"). In a similar fashion, the square lozenge (⌑), part of the BCDIC character set, was often used on tabulation listings to indicate second level totals in banking installations in the 1960s.
The APL programming language uses the lozenge, called diamond, as statement separator.
