Franz von Reber,
History of Ancient Art
“ The architecture of Egypt was practised in a manner to show almost no historical development—with the sculpture this is the case in still greater degree. The most ancient carved remains, which with reasonable security may be assigned to the fifth dynasty, show the formal system, retained during the subsequent twenty centuries, as already perfected. Even at that early date the network of lines, which the Egyptian sculptors (more as mechanics than as artists) followed down to the time of the Ptolemies, was already calculated and introduced as a canon. ”
