Ultraviolet light reveals how ancient Greek statues really looked

Original Greek statues were brightly painted, but after thousands of years, those paints have worn away. Find out how shining a light on the statues can be all that’s required to see them as they were thousands of years ago.
Although it seems impossible to think that anything could be left to discover after thousands of years of wind, sun, sand, and art students, finding the long lost patterns on a piece of ancient Greek sculpture can be as easy as shining a lamp on it. A technique called ‘raking light’ has been used to analyze art for a long time. A lamp is positioned carefully enough that the path of the light is almost parallel to the surface of the object. When used on paintings, this makes brushstrokes, grit, and dust obvious. On statues, the effect is more subtle. Brush-strokes are impossible to see, but because different paints wear off at different rates, the stone is raised in some places – protected from erosion by its cap of paint – and lowered in others. Elaborate patterns become visible.
Ultraviolet is also used to discern patterns. UV light makes many organic compounds fluoresce. Art dealers use UV lights to check if art has been touched up, since older paints have a lot of organic compounds and modern paints have relatively little. On ancient Greek statues, tiny fragments of pigment still left on the surface glow bright, illuminating more detailed patterns.
Once the pattern is mapped, there is still the problem of figuring out which paint colors to use. A series of dark blues will create a very different effect than gold and pink. Even if enough pigment is left over so that the naked eye can make out a color, a few thousand years can really change a statue’s complexion. There’s no reason to think that color seen today would be anything like the hues the statues were originally painted.
There is a way around this dilemma. The colors may fade over time, but the original materials – plant and animal-derived pigments, crushed stones or shells – still look the same today as they did thousands of years ago. This can also be discovered using light.
Infrared and X-ray spectroscopy can help researchers understand what the paints are made of, and how they looked all that time ago. Spectroscopy relies on the fact that atoms are picky when it comes to what kind of incoming energy they absorb. Certain materials will only accept certain wavelengths of light. Everything else they reflect. Spectroscopes send out a variety of wavelengths, like scouts into a foreign land. Inevitably, a few of these scouts do not come back. By noting which wavelengths are absorbed, scientists can determine what materials the substance is made of. Infrared helps determine organic compounds. X-rays, because of their higher energy level, don’t stop for anything less than the heavier elements, like rocks and minerals. Together, researchers can determine approximately what color a millennia-old statue was painted.

Artists ’have structurally different brains’
2014 04 17
Artists have structurally different brains compared with non-artists, a study has found.
Participants’ brain scans revealed that artists had increased neural matter in areas relating to fine motor movements and visual imagery.
The research, published in NeuroImage, suggests that an artist’s talent could be innate.
But training and environmental upbringing also play crucial roles in their ability, the authors report.
