This is the original Numberism drawing of "Mirabilis", hand drawn with pen, color pencil and pencil on paper, and is framed and ready to hang. It is signed and comes with a certificate of authenticity and a magnifying glass. 

The image is 24" x 16" with an angled archival mat. 

The wood is drawn with the main wood resonance of a Cello body. The strings are drawn with a formula to get the standing wave pattern of a single plucked string. The trim is drawn with the average density of ebony.

The scroll is drawn with equations to solve for the polar coordinates of this Logarithmic Spiral (also known as the Spira Mirabilis)

The bow is drawn with the average density of ebony, while the hairs are drawn with the average number of hairs on a single bow.
