The Largest Mirror In The World, Salt Field, Bolivia

Mirrors have been used by artists to create works and hone their craft:
• Filippo Brunelleschi discovered linear perspective with the help of the mirror.
• Leonardo da Vinci called the mirror the "master of painters". He recommended, "When you wish to see whether your whole picture accords with what you have portrayed from nature take a mirror and reflect the actual object in it. Compare what is reflected with your painting and carefully consider whether both likenesses of the subject correspond, particularly in regard to the mirror."
