Johannes Kepler's Latin essay of 1611, 'On the Six-Cornered Snowflake', is here presented in an English translation by Colin Hardie. The text is accompanied by essays from Brian J. Mason and Lancelot Law Whyte, describing the place Kepler's work holds in the development of crystallography.

German mathematician Johannes Kepler (1571-1630), revolutionised the Copernican heliocentric theory of the universe with his three laws of motion: that planets move not in circular but elliptical orbits, that their speed is greatest when nearest the sun, and that the sun and planets form an integrated system. This title contains two of his works.
