Greek Sundial — Carving a Hemispherical Sundial
Carve a Greek hemispherical sundial (scaphe), a concave bowl with hour lines carved on its interior surface and a gnomon (shadow-casting pin) at the center. Attributed to the Babylonian astronomer Berossus (3rd century BCE), this design projects the sun's path as a moving shadow point across the curved inner surface of the bowl.
