The Sundial..

The Sundial is a device used to tell the time of day by the position of the Sun. In this design which is a horizontal sundial, the Sun casts a shadow from its stylus onto a surface marked with lines, and some not marked, indicating the hours of the day by a thin rod known as a gnomon. On this sundial, as the Sun moves across the sky, the shadow-edge aligns with imagined numbers of the hour. All sundial must be aligned with their styles parallel to the axis of the earth' s rotation to tell the correct time throughout the year. The hour angle must be geographically and horizontally correct as well. There is a sundial located on the old church in High Amana, now the Amana Art Guild, and on the Lace Haus, the former Gene Leichsenring home, in Amana.
