Hirst selected the photograph and enlarged it in 1991 for one of his early solo shows, though it had been taken several years earlier. He said of the photograph, «I wanted to show my friends, but I couldn’t take all my friends there, to the morgue in Leeds. This early piece, indicative of his preoccupation with the relationship between life and death, is gruesome, satirical, and disturbing, evoking the conflicting feelings of repulsion and fascination many feel when confronted with the physical realities of death. Hirst’s first solo exhibition, held in London in 1991, built upon his established reputation for using live animals in his work. The artist glued pupa onto white canvases, where they hatched into butterflies, fed on bowls of fruit, mated, and subsequently died. Hirst revisited the theme of butterflies in an installation at the Tate Modern in 2012. Two windowless rooms were filled with live butterflies, brought in daily by the butterfly expert from London’s Natural History Museum and swept up insect o cutor the museum staff when they perished. This series are his most recognizable and iconic works, aside from his animal sculptures.

No one knows how many there are, but estimates are in the thousands. The cheerful impact of these canvases might at first seem at odds with Hirst’s preoccupation with mortality. In fact, they are very much in keeping with it. Each of Hirst’s dot compositions mimics the molecular structure of an addictive, potentially lethal substance that cannot be accessed without a doctor’s consent. These paintings thus constitute a witty, withering comment on a multi-billion dollar pharmaceutical industry that dispenses drugs like candy.

They are also a nod to earlier colorists Hirst admires, among them Gerhard Richter and Mark Rothko. So that’s what the spot paintings came from — to create that structure to do those colors, and do nothing. I suddenly got what I wanted. It was just a way of pinning down the joy of color. The work is related to the spot paintings, named after pharmaceuticals, but the impact is strikingly different. According to the artist, this work was inspired by walking into a pharmacy and marveling at its ability «to provoke an idea of confidence. This floor-based sculpture is comprised of four glass tanks, each of which contains one bisected half of a cow and calf. The white wood frames on each tank evoke the pure, clean lines of classic Minimalist sculpture.

Their contents, however, are neither clean nor minimalist. Each animal is suspended above the base of the tank, its front legs dangling limply, deepening the sense of lifelessness. In focusing on the physical consequences of death, the piece hearkens back to another time-honored theme in western art, that of the memento mori, a class of images devoted to reminding viewers of the inevitability of death and the immortality of the soul. Hirst’s work has both these qualities. While certainly a reminder of death, the bodies are suspended in a substance that makes them weightless. For the past decade, he has focused heavily on butterflies, both as symbols and literal materials. Butterflies, traditionally a symbol of the resurrection of Christ, assume a broader significance in Hirst’s work, where they are emblematic of ascendance, a theme also found in the animal installations, where bodies seem suspended in midair. Hirst’s preserved corpses heighten our awareness of the fleeting nature of life and the possibility of something beyond it.

According to the New York Times, it was inspired by an exasperated comment from Hirst’s mother about his work: «for the love of God, what are you going to do next? The skull, a symbol of mortality, fits within a long tradition of such reminders. Damien Hirst Artist Overview and Analysis». First published on 29 Feb 2016. The violet glow of a black light is not the UV light itself, but visible light that escapes being filtered out by the filter material in the glass envelope. Paints and decorations that fluoresce under black light are used in theater and several art forms.

One type of lamp has a violet filter material, either on the bulb or in a separate glass filter in the lamp housing, which blocks most visible light and allows through UV, so the lamp has a dim violet glow when operating. A second type of lamp produces ultraviolet but does not have the filter material, so it produces more visible light and has a blue color when operating. Although many other types of lamp emit ultraviolet light with visible light, black lights are essential when UV-A light without visible light is needed, particularly in observing fluorescence, the colored glow that many substances emit when exposed to UV. UV-A presents a potential hazard when eyes and skin are exposed, especially to high power sources. According to the World Health Organization, UV-A is responsible for the initial tanning of skin and it contributes to skin ageing and wrinkling. UV-A may also contribute to the progression of skin cancers. Two black light fluorescent tubes, showing use. BLB 18-inch, 15-watt tube, used in a standard plug-in fluorescent fixture.

BLB 12-inch, 8-watt tube, used in a portable battery-powered black light sold as a pet urine detector. Fluorescent black light tubes are typically made in the same fashion as normal fluorescent tubes except that a phosphor that emits UVA light instead of visible white light is used. Blacklight blue» lamps peak at 365 nm. Manufacturers use different numbering systems for black light tubes. Osram system is becoming dominant outside North America. The following table lists the tubes generating blue, UVA and UVB, in order of decreasing wavelength of the most intense peak. Spectrum of a black light fluorescent tube. FWHM spectral bandwidth of the 370 nm peak is about 20 nm.

404 nm leaking through the filter, which gives the lamp its purple glow. Another class of UV fluorescent bulb is designed for use in «bug zapper» flying insect traps. Insects are attracted to the UV light, which they are able to see, and are then electrocuted by the device. A black light may also be formed by simply using a UV filter coating such as Wood’s glass on the envelope of a common incandescent bulb. This was the method that was used to create the very first black light sources. High power mercury vapor black light lamps are made in power ratings of 100 to 1,000 watts. Ultraviolet light can be generated by some light-emitting diodes, but wavelengths shorter than 380 nm are uncommon, and the emission peaks are broad, so only the very lowest energy UV photons are emitted, within predominant not visible light.

Some forms of tinea, such as Trichophyton tonsurans, do not fluoresce. Cutibacterium acnes, a bacterium involved in acne causation, exhibits an orange glow under a Wood’s lamp. A Wood’s lamp may be used to rapidly assess whether an individual is suffering from ethylene glycol poisoning as a consequence of antifreeze ingestion. 470 nm, used to treat neonatal jaundice. Uranium glass glows under UV light. Although black lights produce light in the UV range, their spectrum is mostly confined to the longwave UVA region, that is, UV radiation nearest in wavelength to visible light, with low frequency and therefore relatively low energy.

While low, there is still some power of a conventional black light in the UVB range. UVA light has been shown to cause DNA damage, but not directly, like UVB and UVC. UV-A can have negative effects on eyes in both the short-term and long-term. Ultraviolet radiation is invisible to the human eye, but illuminating certain materials with UV radiation causes the emission of visible light, causing these substances to glow with various colors. This is called fluorescence, and has many practical uses. Black lights are required to observe fluorescence, since other types of ultraviolet lamps emit visible light which drowns out the dim fluorescent glow. Black light is commonly used to authenticate oil paintings, antiques and banknotes. Black lights can be used to differentiate real currency from counterfeit notes because, in many countries, legal banknotes have fluorescent symbols on them that only show under a black light.

Other security applications include the use of pens containing a fluorescent ink, generally with a soft tip, that can be used to «invisibly» mark items. If the objects that are so marked are subsequently stolen, a black light can be used to search for these security markings. In medicine, the Wood’s lamp is used to check for the characteristic fluorescence of certain dermatophytic fungi such as species of Microsporum which emit a yellow glow, or Corynebacterium which have a red to orange color when viewed under a Wood’s lamp. Black light can also be used to see animal excreta such as urine and vomit that is not always visible to the naked eye. Black light is used extensively in non-destructive testing. Fluorescing fluids are applied to metal structures and illuminated with a black light which allows cracks and other weaknesses in the material to be easily detected. It is also used to illuminate pictures painted with fluorescent colors, particularly on black velvet, which intensifies the illusion of self-illumination. Thousands of moth and insect collectors all over the world use various types of black lights to attract moth and insect specimens for photography and collecting.

It is one of the preferred light sources for attracting insects and moths at night. It may also be used to test for LSD, which fluoresces under black light while common substitutes such as 25I-NBOMe do not. In addition, if a leak is suspected in a refrigerator or an air conditioning system, a UV tracer dye can be injected into the system along with the compressor lubricant oil and refrigerant mixture. The system is then run in order to circulate the dye across the piping and components and then the system is examined with a blacklight lamp. 20 bill glows green under black light as a safeguard against counterfeiting. Anti-counterfeiting design of a Chinese passport glows under black light. Compiled from various Philips, Osram, and Sylvania lighting catalogues.

A class of images devoted to reminding viewers of the inevitability of death and the immortality of the soul.
