In Hindu Iconography, Shiva is often shown wearing a crescent moon on his head, symbolising his control over time, as well as his attributes of both creation and destruction.
In Christian symbolism, the crescent entered Marian iconography, by the association of Mary with the Woman of the Apocalypse (described with "the moon under her feet, and on her head a crown of twelve stars" in Revelation) The most well known representation of Mary as the Woman of the Apocalypse is the Virgin of Guadalupe.
[7] The word crescent is derived etymologically from the present participle of the Latin verb crescere "to grow", technically denoting the waxing moon (luna crescens).
[8] 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 appears in a different shape from what is generally termed a crescent in planar geometry: Assuming the terminator lies on a great circle, the crescent Moon will actually appear as 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.
In addition, there is a 19th-dynasty hieroglyph representing the "moon with its lower half obscured (N9 psḏ, with a variant with a crescent shape N10 ).
[9] The crescent was well used in the iconography of the ancient Near East and was used by the Phoenicians in the 8th century BC as far as Carthage and Numidia in modern Tunisia and Algeria.
Selene, the moon goddess, was depicted with a crescent upon her head, often referred to as her horns, and a major identifying feature of hers in ancient works of art.
[12][13] In the iconography of the Hellenistic period, the crescent became the symbol of Artemis-Diana, the virgin hunter goddess associated with the Moon.
Anna Notaras, daughter of the last megas doux of the Byzantine Empire Loukas Notaras, after the fall of Constantinople and her emigration to Italy, made a seal with her coat of arms which included "two lions holding above the crescent a cross or a sword".
Examples include the flags attributed to Gabes, Tlemcen, Tunis and Buda,[18] Nubia/Dongola (documented by Angelino Dulcert in 1339) and the Mamluks of Egypt.
[19] The Roman Catholic fashion of depicting Madonna standing or sitting on a crescent develops in the 15th century.
In reference to this, feminine jewelry representing crescents, especially diadems, became popular in the early modern period.
[23] The identification of the crescent as an "Islamic symbol" is mentioned by James Hastings as a "common error" to which "even approved writers on Oriental subjects" are prone as early as 1928.
[30] Crescents, often with faces, are found on numerous modern municipal coats of arms in Europe, e.g. Germany: Bönnigheim, Dettighofen, Dogern, Jesenwang, Karstädt, Michelfeld (Angelbachtal), Waldbronn; Switzerland: Boswil, Dättlikon, Neerach (from the 16th-century Neuamt coat of arms); France: Katzenthal, Mortcerf; Malta: Qormi; Sweden: Trosa.
The crescent printed on military ration boxes is the US Department of Defense symbol for subsistence items.
