As the day progresses, the sun moves across the sky, causing the shadow of the object to move and indicating the passage of time. The first device for indicating the time of day was probably the gnomon , dating from about bce. It consisted of a vertical stick or pillar , and the length of the shadow it cast gave an indication of the time of day.
By the 8th century bce more-precise devices were in use. The earliest known sundial still preserved is an Egyptian shadow clock of green schist dating at least from this period. The shadow clock consists of a straight base with a raised crosspiece at one end. The base, on which is inscribed a scale of six time divisions, is placed in an east-west direction with the crosspiece at the east end in the morning and at the west end in the afternoon.
The shadow of the crosspiece on this base indicates the time. Clocks of this kind were still in use in modern times in parts of Egypt. Another early device was the hemispherical sundial, or hemicycle, attributed to the Greek astronomer Aristarchus of Samos about bce.

This was mostly because of lack of time and resources, but as I have come to learn about, and appreciate, the manufacturing art and long history of abaci in various cultures.
I have become a great fan of ‘bead math’ or ‘counting beads’ and am just learning the intracacies of their use and usefulness.

Originally thought to be a gaming board, the slab of white marble is currently at the Epigraphical Museum in Athens. Five groups of markings appear on the tablet. The three sets of Greek symbols arranged along the left, right and bottom edges of the tablet are numbers from the acrophonic system. In the center of the tablet — a set of five parallel lines equally divided by a vertical line, capped with a semicircle at the intersection of the bottom-most horizontal line and the single vertical line.
Below a wide horizontal crack is another group of eleven parallel lines. These are divided into two sections by a line perpendicular to them but with the semicircle at the top of the intersection; the third, sixth and ninth of these lines are marked with a cross where they intersect with the vertical line. As with an abacus, pebbles represent small numbers generally between zero and four and a system of lines serves to group them by powers of ten.
A pebble between the lines represents half the value of a pebble on the line above it.

Addition and subtraction can easily be performed by moving beads along the wires of the abacus. The word abacus is Latin. It is taken from the Greek word abax , which means “flat surface.
Often they were simply boards or tables on which pebbles or stones could be moved to show addition or subtraction.
