Knossos: Fakes, Facts, and Mystery. "The masterpieces of Minoan art are not what they seem... The truth is that these famous icons are largely modern. As any sharp-eyed visitor to the Heraklion museum can spot, what survives of the original paintings amounts in most cases to no more than a few square inches. The rest is more or less imaginative reconstruction, commissioned in the first half of the twentieth century by Sir Arthur Evans, the British excavator of the palace of Knossos (and the man who coined the term 'Minoan' for this prehistoric Cretan civilization, after the mythical King Minos who is said to have held the throne there). As a general rule of thumb, the more famous the image now is, the less of it is actually ancient."

Paintings of Buddha dating back at least to the 12th century have been discovered in a cave in Nepal. Tipped by a local shepherd, a team of international researchers climbed to some old caves where they found a mural with 55 panels depicting the life of Buddha, reminiscent of the artwork of the Ajanta Caves in India (possibly NSFW). There are probably many other forgotten caves in the Mustang area (previously discussed here,) but they may be threatened by a planned trans-Himalayan highway.
A restoration project has been underway since 1998 to restore the 15th-century Tibetan Buddhist monastery wall paintings of Lo Monthang, a city in the kingdom of Mustang in northwest Nepal. The results have been very impressive. Mustang is also home to some amazing cave temples.
