Archaeologist Vinzenz Brinkmann makes color reconstructions of ancient Greek and Roman sculpture. His work is on display at Harvard University's Sackler Museum. From the Wall Street Journal:
The fashion for white antiquities dates back to the early 16th century, when the Renaissance began excavating works that had lain buried in the earth for centuries. Color traces still visible to the naked eye, deep in the folds of draped clothing, for instance, went unnoticed. Following what they believed to be the Greek and Roman example, Italian sculptors — notably Michelangelo — conceived their creations as uncolored. By the 18th century, practitioners of the then-new science of archaeology were aware that the ancients had used color. But Johann Joachim Winckelmann, the German prefect of antiquities at the Vatican, preferred white. His personal taste was enshrined by fiat as the "classical" standard. And so it remained, unchallenged except by the occasional eccentric until the late 20th century.[Photograph: Trojan archer, original c. 490–480 BCE, color reconstruction by Vinzenz Brinkmann and Ulrike Koch-Brinkmann.]
