In enumerating and analysing the remains of Egyptian art, we shall classify them chronologically as well as locally. The monuments of the plastic arts will be arranged into groups determined by the periods of their occurrence, as well as by their geographical distribution. We must refer our readers to the works of M. Maspero and others for the lists of kings and dynasties, and for the chief events of each reign, but it will be convenient for us to give here a summary of the principal epochs in Egyptian history. Each of those epochs corresponds to an artistic period with a special character and individuality of its own. The following paragraphs taken from the history of M. Maspero give all the necessary information in a brief form. "In the last years of the prehistoric period, the sacerdotal class had obtained a supremacy over the other classes of the nation. A man called Menes (Menha or Ména in the Egyptian texts) destroyed this supremacy and founded the Egyptian monarchy. "This monarchy existed for at least four thousand years, under thirty consecutive dynasties, from the reign of Menes to that of Nectanebo (340 years before our era). This interval of time, the longest of which political history takes note, is usually divided into three parts: the _Ancient Empire_, from the first to the eleventh dynasty; the _Middle Empire_, from the eleventh dynasty to the invasion of the Hyksos or Shepherds; the _New Empire_ from the shepherd kings to the Persian conquest. This division is inconvenient in one respect; it takes too little account of the sequence of historical events. "There were indeed, three great revolutions in the historical development of Egypt. At the beginning of its long succession of human dynasties (the Egyptians, like other peoples, placed a number of dynasties of divine rulers before their first human king) the political centre of the country was at Memphis; Memphis was the capital and the burying-place of the kings; Memphis imposed sovereigns upon the rest of the country and was the chief market for Egyptian commerce and industry. With the commencement of the sixth dynasty, the centre of gravity began to shift southwards. During the ninth and tenth dynasties it rested at Heracleopolis, in Middle Egypt, and in the time of the eleventh dynasty, it fixed itself at Thebes. From that period onwards Thebes was the capital of the country and furnished the sovereign. From the eleventh to the twenty-first all the Egyptian dynasties were Theban with the single exception of the fourteenth Xoite dynasty. At the time of the shepherd invasion, the Thebaïd became the citadel of Egyptian nationality, and its princes, after centuries of war against the intruders, finally succeeded in freeing the whole valley of the Nile for the benefit of the eighteenth dynasty, which opened the era of great foreign wars.
