The First Iconoclasm, [1] as it is sometimes called, occurred between about 726 and 787, while the Second Iconoclasm occurred between 814 and 842. [2] According to the traditional view, Byzantine Iconoclasm was started by a ban on religious images promulgated by the Byzantine Emperor Leo III the Isaurian , [ 3 ] and continued under his ...
The first act of Muslim iconoclasm dates to the beginning of Islam, in 630, when the various statues of Arabian deities housed in the Kaaba in Mecca were destroyed. There is a tradition that Muhammad spared a fresco of Mary and Jesus. [55] This act was intended to bring an end to the idolatry which, in the Muslim view, characterized Jahiliyyah.
Widespread destruction of images occurred during the Byzantine Iconoclasm of 726–842, although this did settle permanently the question of the appropriateness of images. Since then, icons have had a great continuity of style and subject, far greater than in the icons of the Western church .
Print of the destruction in the Church of Our Lady in Antwerp, the "signature event" of the Beeldenstorm, 20 August 1566, by Frans Hogenberg [1]. Beeldenstorm (pronounced [ˈbeːldə(n)ˌstɔr(ə)m]) in Dutch and Bildersturm [ˈbɪldɐˌʃtʊʁm] in German (roughly translatable from both languages as 'attack on the images or statues') are terms used for outbreaks of destruction of religious ...
1021 – Ibn al-Haytham (Alhacen) pioneers the experimental scientific method and experimental physics in his Book of Optics, where he devises the first scientific experiments on optics, including the first use of the camera obscura to prove that light travels in straight lines and the first experimental proof that visual perception is caused ...
1957: Marvin Minsky, a professor at MIT, invents the confocal microscope, an optical imaging technique for increasing optical resolution and contrast of a micrograph by means of using a spatial pinhole to block out-of-focus light in image formation. This technology is a predecessor to today's widely used confocal laser scanning microscope.
This technique involves tilting the light sheet relative to the detection objective at a precise angle to allow the light sheet to form on the surface of glass coverslips. Light sheet fluorescence microscopy was combined with Adaptive Optics techniques in 2012 to improve the depth of imaging in thick and inhomogenous samples at a depth of 350 ...
The optical microscope, also referred to as a light microscope, is a type of microscope that commonly uses visible light and a system of lenses to generate magnified images of small objects. Optical microscopes are the oldest design of microscope and were possibly invented in their present compound form in the 17th century.
