Pyrămis

(πυραμίς). A pyramid; a form of structure which doubtless originated with the Egyptians, though it was adopted by the Etruscans and Romans, and is found in the so-called Cyclopean remains in Greece. (See Cyclopes, p. 451.) The Romans used the pyramid as a design for sepulchral monuments (see illustration, p. 732), a fine existing specimen being the tomb of C. Cestius on the Appian Way just outside of Rome. The tomb of Augustus, remains of which are still to be seen, was pyramidal, rising to the height of some 328 feet. (See Augustus.) The pyramidal form is found in the Birs-Nimrûd or Tower of Belus (see pages 175, 176), and it occurred in the famous mausoleum at Halicarnassus. See illustration, p. 1018.
