Back in the Renaissance, Leonardo da Vinci designed a large monumental horse, which was to be cast in bronze. The casting never happened--the metal was use to make weapons instead. Jean Fritz wrote a book for children called Leonardo's Horse [J 730 FRI] which tells the story of the project, and how it was actually completed centuries later.
As you can see from the book's cover, the horse was more than larger than life, it was colossal!
Artists have often worked to create colossal pieces. Just consider the Statue of Liberty and the sculpted portraits at Mount Rushmore.
Today, colossal art is still looked upon as a wonder. To see what I mean, click here. I discovered Colossal: Art & Visual Culture not too long ago, and every time I go back for a visit, I am amazed!
