I used to wonder, who colored these beautiful wings! How does the peacock get his iridescent color? Amazingly, the peacock feathers haven no pigment in the feathers--the color is produced by light-processing structures formed by careful arrangement of the little barbs and barbules of the feather, which form a diffraction grating.

The structure of these micro barbs in the feather is on the order of 100,000 dots per inch, which gives a grid spacing approximating the wavelength of light, and produces these incredible color effects.

The iridescent blue-green color is very similar to that produced by the optical structures of the morpho butterfly, but uses a totally different principle to cause the color to appear. If the peacock feather is viewed from the backside, the blue dot disappears. The color is truly in the eye of the beholder, not in the feather.

Isn't God a great artist?

Much love and blessings

A steep climb is the only way up to the convent, which is said to date back to the Emperor Justinian.

Legend has it that the Virgin Mary appeared to Justinian and asked him to found the convent.

After entering through a maze of passages, you finally reach the Chapel of the Virgin. The walls are covered with beautiful icons including one said to have been painted by St. Luke.

This chapel was very famous to Christians and at one point was the second Christian place of pilgrimage after Jerusalem, the crusaders called it "Notre Dame de Sardeneye".
