- For things named Crescent, see Crescent (disambiguation).
An example of an artistic crescent — in this case a large circle with a smaller one removed.
An astronomically correct crescent shape (in blue), complemented by a gibbous shape.
In art and symbolism, a crescent is generally the shape produced when a circular disk has a segment of another circle removed from its edge, so that what remains is a shape enclosed by two circular arcs of different diameters which intersect at two points (usually in such a manner that the enclosed shape does not include the center of the original circle).
In astronomy, a crescent is the shape of the lit side of a spherical body (most notably the Moon) that appears to be less than half illuminated by the Sun as seen by the viewer. Mathematically, assuming the terminator lies on a great circle, such a crescent will actually be the figure bounded by a half-ellipse and a half-circle, with the major axis of the ellipse coinciding with a diameter of the semicircle. The direction in which the "horns" (the points at the intersection of the two arcs) face indicates whether a crescent is waxing (also young, or increasing) or waning (also old, or decreasing). Eastward pointing horns (pointing to the left, as seen from the Northern hemisphere) indicate a waxing crescent, whereas westward pointing horns (pointing to the right, as seen from the Northern hemisphere) indicate a waning crescent. Note that the directions the horns point relative to the observer are reversed in the Southern hemisphere.
The crescent and star, while generally regarded as Islamic symbols today, have long been used in South Arabia[1] as a symbol[2] and in coinage, by the Göktürks and the Sassanids of Persia and is prominently displayed on their crowns of their rulers[3]. After the founding of the Arab Caliphate, the symbol was used. gradually adopted by later caliphates and Muslim rulers as an established and recognized symbol of power in Western Asia. It was also a symbol of the Ottoman Empire. Though the crescent was originally a secular symbol of authority for Muslim rulers, it is now often used to symbolize the Islamic faith. However, it should be noted that the crescent was not a symbol used for Islam by Muhammad or any other early Muslim rulers, as the Islamic religion is, in fact, against appointing "Holy Symbols" (so that during the early centuries of Islam, Muslim authorities simply didn't want any geometric symbols to be used to symbolize Islam, in the way that the cross symbolizes Christianity, the menorah was a commonly-occurring symbol of Judaism, etc.). This is why early Islamic coins were covered with Arabic writing, but contained no visual symbols of any kind, although the symbol it self was used in Al-Andalus by the Nasrids flag was used by the Mamluks.
Despite this mixed history, many Islamic nations and charities use the crescent symbol on their flags or logos (e.g. Pakistan, The Red Crescent, etc. — though currently none of the Arab states in Arabia or the Mashreq have crescents on their flags). Therefore it could be argued that this usage is meant to signify Islamic identity or Muslim brotherhood.
Note that in the case of an astronomical crescent, such as the moon observed in the sky, the outer arc will be 180° (a half-circle as previously mentioned), while the Islamic crescent symbol (Arabic هلال hilāl) is generally shown with an outer arc significantly greater than 180° (as seen in the illustrations above).
The crescent moon is also a symbol associated with the Hindu's iconography: with the deity Shiva, who wears it at the top of his matted hair.
The crescent is also used as a heraldic symbol. However, this usage is not affiliated in any way with Islam. The roots of the Slavic crescent can be traced to the old Slavic pagan beliefs. In English and Canadian heraldry a crescent is the cadence mark of a second son.
The crescent symbol is also used to represent the moon in astronomy and astrology, and to represent silver (the metal associated with the moon) in alchemy, where, by inference, it can also be used to represent qualities that silver possesses. (Alchemy and Symbols, By M. E. Glidewell, Epsilon.)

The origin is the crescent shape of the old city, hugging the East Bank of the Mississippi River. The historical crescent, which includes the French Quarter and was one of the few places where settlement was possible before the construction of the levee system, did not flood during Hurricane Katrina. The choice of the star and crescent symbol is a relic of the krewes, many of which adopted "Oriental" costume and rituals, like other societies of the 19th century.
