ARTIST STATEMENT

A sense of order has always been an important part of my work.  “The Uranometria Series” has grown out of this concern and my avocational interest in astronomy.  The word “Uranometria” is derived from the Greek word “uranos”, meaning sky or heavens.  A literal translation of “Uranometria” is “measuring the sky”.  This along with its counterpart, “Geometria” (geometry) - or measuring the Earth are the inspiration for the two major components in each drawing.  Early astronomers mapped the night sky by connecting groups of stars together with imaginary lines creating constellations; cartographers mapped the Earth with imaginary lines of longitude and latitude drawn upon the landscape.  By layering lines upon the paper, referencing an image from a 17th century star chart, a da Vinci drawing, plumb bob, and calculations from the notebook of Edwin Hubble, I have tried to define and develop the surface of the drawing just as a surveyor and astronomer define the earth and sky.

Edwin Hubble’s hand-written chart where he used period-luminosity relationships to determine the distance to the Andromeda Galaxy and confirmed that it is located beyond the limits of the Milky Way.

Uranometria Series: Galileo’s Observation

Uranometria Series: Claudius’ Hypotheses

graphite and digital print on vellum


Claudius Ptolemy employed off-center circles called eccentrics and epicycles to explain the motion of the planets within a Earth-centered universe.  Although Ptolemy lived in 2nd century, his work first appeared in print in a 16th century Italian manuscript.

Uranometria Series: Isaac’s Proposal


graphite and digital print on vellum


A diagram of a catadioptrical telescope proposed by Sir Isaac Newton which involved passing light through a concave lens, then bouncing it off a flat speculum, or mirror, and on to the eyepiece of the telescope.

Uranometria Series: Johann’s Burin


graphite and digital print on vellum


Considered the key forerunner of all later star atlases, Johann Bayer’s 1603 “Uranometria” contains fifty-one star charts that were engraved on metal plates, rather than woodcuts.

Uranometria Series: Albert’s Prediction

graphite and digital print on vellum


The first page of a letter from Albert Einstein to 
George Ellery Hale, 14 October 1913 in which Einstein predicts that light could be bent by a gravitational field - a tenet of his general theory of relativity.
