Later, Egyptians made marks on the ground around the obelisk to further divide the time of day into shorter segments that are similar to the hours we use today. 4 Around 1500 ec. Egyptians began using sundials, which are essentially smaller versions of obelisks. These ingenious time devices are made by placing a rod in the middle of a circular base that is marked in increments showing the passage of time. Sundials were placed outside in the sun and observers could tell what time of day it was by seeing which mark the shadow fell upon. Sundials were usually portable and allowed people to know what time it was even if they were far from an obelisk. They were very popular throughout Europe and the Middle East until the middle of the 14th century. 5 Although sundials allowed people to measure time with a fair amount of accuracy when the sun was shining, these instruments did not give people the ability to measure time at night or on cloudy days. Water clocks, the first timekeepers people used that did not depend upon the sun, appeared in Egypt as early as 2000 ac. These were used by the Egyptians and then later by the Greeks, who called them clepsydras (klp'si-dras), or \"water thieves\"\" i_t_ @e05000 Cre TestNav User de Based on paragraph 4, the reader can determine that the sundial was the first timekeeping device to A. measure time more accurately than an obelisk B. havea rod that indicated the location of the sun C. make timekeeping more accessible 0D. divide the day into specific hours 206 Dec 16 755 9
