[[File:Bowl of Ahaz refracting scaphe sundial, by Georg Hartman, Nuremberg, c. 1525-1564 - Putnam Gallery - Harvard University - DSC07927.jpg|thumb|right|"Georg Hartmann, German, 1525-1564, Bowl of Ahaz [Refracting scaphe sundial], Nuremberg, 1548, Brass Collection of Historical Scientific Instruments, Department of the History of Science, Harvard"]] The scaphe (; also known as a skaphe, scaphion (diminutive) or ) was a sundial said to have been invented by Aristarchus of Samos (3rd century BC). There are no original works still in existence by Aristarchus, but the adjacent picture is an image of what it might have looked like; only his would have been made of stone. It consisted of a hemispherical bowl which had a vertical gnomon placed inside it, with the top of the gnomon level with the edge of the bowl. Twelve gradations inscribed perpendicular to the hemisphere indicated the hour of the day.
