Math is used in art all the time.

One example is the work of Leonardo Da Vinci. Da Vinci created a lot of his art according to the *Golden Ratio*, such as in two of his most famous pieces: *The Mona Lisa* and *The Vitruvian Man*.

In art, The Golden Ratio is a proportion that is said to be aesthetically pleasing. The *Golden Rectangle* is used in many places in the Mona Lisa, the face being one of them.

Another example is the famous painting *The Sacrament of the Last Supper* by Salvador Dali, which also uses the Golden Rectangle compositionally.

M. C. Escher’s work used mathematics and geometry. A lot of his pieces were tessellations.

Many of his works used *impossible objects* like the *Penrose Triangle*. Impossible objects are optical illusions consisting of a 2-dimensional figure that look 3-dimensional, but are impossible to actually exist.
