Theorem painting by Nancy Rosier

Theorem Painting by American Folk Artist Nancy Rosier are paintings created with the aid of stencils and is considered traditional folk art. Theorem paintings were popular in the 1800s. Theorem painting is most often done on white velvet fabric, which gives the painting a soft, lovely depth. Oil paint is presently used as it simulates the look of the antique theorems whose paint was hand mixed.

What is a Theorem Painting?

Theorem painting (meaning painting with the aid of stencils) is considered traditional folk art. It was popular in the 1800s. Theorem painting is most often done on white velvet fabric, which gives the painting a soft, lovely depth. Fruit and floral arrangements are the most popular subjects, but scenes were sometimes done.

Colonial Williamsburg Theorem Exhibit

As a contemporary folk artist specializing historically based theorem painting many years, I am very excited to share the news that Colonial Williamsburg has just opened a long term exhibit on theorem painting in their art museums. I was asked to contribute to the exhibit by participating in a video being shown on how I paint a theorem. It is a vanishing art form, learn what it is. CLICK HERE to learn more!

Grained Frames

Each of my theorem paintings come framed and ready to hang on the wall.  I offer gilded gold frames, but a majority of my frames are hand crafted.  My husband builds each frame and then I hand paint and grain.  This process is called false graining.  I use everything from corncobs to the side of my hand.

Museum Reproductions

Thanks to museums allowing me to photograph, measure, and see the actual theorem, I have been able to create my own adaptation of these historic theorems.
