graven image

Examples of graven image in the following topics:

• Icons and Iconoclasm

  • Emperor Leo III (717-741) and his successors banned the worship of icons and encouraged the persecution of those who venerated images.
  • According to the traditional view, Byzantine Iconoclasm constituted a ban on religious images by Emperor Leo III and continued under his successors, and was accompanied by widespread destruction of images and persecution of supporters of the veneration of images.
  • Conversely, people who revere or venerate religious images are derisively called "iconolaters. "
  • Iconoclasm has generally been motivated theologically by an Old Covenant interpretation of the Ten Commandments, which forbade the making and worshiping of "graven images. " The two periods of iconoclasm in the Byzantine Empire during the 8th and 9th centuries made use of this theological theme in discussions over the propriety of images of holy figures, including Christ, the Virgin and saints.
  • The role of women and monks in supporting the veneration of images has also been asserted.

• Early Jewish Art

  • The Second Commandment, as noted in the Old Testament, warns all followers of the Hebrew god Yahweh, "Thou shalt not make unto thee any graven image."
  • In Judaism, God chooses to reveal his identity, not as an idol or image, but by his words, by his actions in history, and by his working in and through humankind.
  • Its mosaic floor depicts a syncretic image of King David as Orpheus, identified by his name in Hebrew letters.
  • The discovery of the synagogue helps to dispel narrow interpretations of Judaism's historical prohibition of visual images.
  • Discuss how the prohibition of "graven images" influenced the production of Jewish art.

• Architecture and Mosaics in the Middle Byzantine Empire

  • Broadly defined, iconoclasm is defined as the destruction of images.
  • In Christianity, iconoclasm has generally been motivated by people who adopt a literal interpretation of the Ten Commandments, which forbid the making and worshipping of graven images.
  • It was accompanied by widespread destruction of images and persecution of supporters of the veneration of images.
  • The image of the Virgin and Child is a common Christian image, and the mosaic depicts Byzantine innovations and the standard style of the period.
  • The central dome depicts an image of Christ Pantocrator, and the overall decorative program depicts scenes from the life of Christ and images of salvation from both the Old and New Testament.

• Early Christian Art

  • The Old Testament restrictions against the production of graven images (an idol or fetish carved in wood or stone) might have also constrained Christians from producing art.
  • But in the earliest images as many show a stocky and short-haired beardless figure in a short tunic, who can only be identified by his context.
  • In many images of miracles Jesus carries a stick or wand, which he points at the subject of the miracle rather like a modern stage magician (though the wand is significantly larger).
  • The image of The Good Shepherd, a beardless youth in pastoral scenes collecting sheep, was the most common of these images and was probably not understood as a portrait of the historical Jesus.
  • These images bear some resemblance to depictions of kouroi figures in Greco-Roman art.

• Highlighting the Main Points

  • Example is graven on the rock, and the lesson is not soon lost.

• Photography: Recording an Image

  • The camera is the image-forming device, and photographic film or a silicon electronic image sensor is the sensing medium.
  • A larger opening will create a brighter image.
  • However, increasing the ISO will affect the quality of the image: in film the images become grainy, and in digital the image becomes noisier, with more undesirable speckles.
  • Regardless of material, a process must be employed to render the latent image captured by the camera into a viewable image.
  • Digital images may be uploaded to an image server, viewed on a television, or transferred to a computer or digital photo frame.

• Image Reflection by a Plane Mirror

  • A "real" image occurs when light rays actually intersect at the image, and become inverted, or turned upside down.
  • A "virtual" image occurs when light rays do not actually meet at the image.
  • You are fooled into seeing an image!
  • A virtual image is right side up (upright).
  • These diagrams can be used to find the position and size of the image and whether that image is real or virtual.

• Medical Imaging

  • Medical imaging is used to create images of the human body used for clinical purposes, diagnostic procedures or medical science.
  • Two forms of radiographic images are in use in medical imaging; projection radiography and fluoroscopy, with the latter being useful for catheter guidance.
  • This imaging modality utilizes a wide beam of x rays for image acquisition and is the first imaging technique available in modern medicine.
  • Images of the same subject produced with two different imaging systems may be correlated (called image registration) by placing a fiduciary marker in the area imaged by both systems.
  • Nuclear medicine encompasses both diagnostic imaging and treatment of disease, and may also be referred to as molecular medicine or molecular imaging and therapeutics.

• Image Formation by Spherical Mirrors: Reflection and Sign Conventions

  • This image that appears to be behind the mirror is called the image.
  • An image formed by reflection may be real or virtual.
  • A real image occurs when light rays actually intersect at the image, and is inverted, or upside down.
  • A virtual image occurs when light rays do not actually meet at the image.
  • A virtual image is right side up (upright).

• NMR and MRIs

  • Magnetic resonance imaging is a medical imaging technique used in radiology to visualize internal structures of the body in detail.
  • Magnetic resonance imaging (MRI), also called nuclear magnetic resonance imaging (NMRI) or magnetic resonance tomography (MRT), is a medical imaging technique used in radiology to visualize internal structures of the body in detail.
  • MRI utilized the property of nuclear magnetic resonance (NMR) to image the nuclei of atoms inside the body.
  • MRI shows a marked contrast between the different soft tissues of the body, making it especially useful in imaging the brain, the muscles, the heart, and cancerous tissue—as compared with other medical imaging techniques such as computed tomography (CT) or X-rays.
