box with a handle on the side. The outer lid covering the mechanism is convex
in shape. The clock’s dial is made of several silver and bronze plated metal
plates, placed one atop another. The complete hour numbers are engraved on the
edges of bottom plate in Roman numerals (I-XII and I-XII), while the 24 circles
on its brim help determine the time in the dark. In the middle of the plate

scale again (in Arabic numerals 1-12 and in Roman numerals I-XII).

plate in Arabic numeral (1-29). On the traverse of this same plate is the
caption “Al index hida”, numerals (10-40; 10-20), and part of a letter from the
signs of the Zodiac, “da”.
