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."
Many self-portraits are made possible through the use of mirrors:
Without a mirror, the great self-portraits by D�rer, Frida Kahlo, Rembrandt, and Van Gogh could not have been painted.
M. C. Escher used special shapes of mirrors in order to achieve a much more complete view of his surroundings than by direct observation in Hand with Reflecting Sphere (also known as Self-Portrait in Spherical Mirror).
Mirrors are sometimes necessary to fully appreciate art work:
Istv�n Orosz's anamorphic works are images distorted such that they only become clearly visible when reflected in a suitably shaped and positioned mirror.
Other artistic mediumsSome other contemporary artists use mirrors as the material of art:
A Chinese magic mirror is an art in which the face of the bronze mirror projects the same image that was cast on its back. This is due to minute curvatures on its front.
