Distinguishing authentic artifacts from forged or misattributed ones is an essential challenge for archaeologists and art historians. Scientific tests, though, often prove incomplete or inconclusive (or simply misleading). In such cases, the best line of defense against forged artifacts is an expert with a finely honed intuitive sense for authenticity—sometimes called a fakebuster. (In Tetraktys, Dr. Jerusalem is a consummate fakebuster.)
In homage to an important theme in Tetraktys, here is the first of what I plan to make a regular series of fakebusting puzzles.
Can you use your fakebusting skills to figure out which image is real and which is fake?
