There are two works of art at the Louvre that are so incredibly famous, that when I saw them in person, I got the sensation of meeting a celebtrity. Both are women-- Mona Lisa, and the Venus de Milo.
Lonardo Da Vinci's Mona Lisa hangs behind a shield of bullet-proof glass that is continually reflecting the flash of cameras. Her fame turns average museum-goers into an eager mob of paparazzi.
The Venus de Milo stands at the end of a long hall, and as you approach her, your heart beats faster with every step. Her base raises her above the heads of museum-goers vying for a full-length view to take a picture, and she is luminous, framed perfectly by an arched doorway.
With such celebrities, it is no wonder that the Louvre is the most visited museum in the world.
