Who would not like to know the course of study by which the ancient Egyptian builders prepared themselves for the great public enterprises which were always going on in their country? We may admit that the methods employed by their engineers were much more primitive than it has been the fashion to suppose, we may prove that their structures were far from possessing the accuracy of plan that distinguishes ours, but yet we cannot deny that those who transported and raised the obelisks and colossal statues, and those who constructed the hypostyle hall of Karnak, or even the pyramids of Gizeh, must have learnt their trade. How and where they learnt it we do not know. It is probable that they learnt it by practice under a master. Theory cannot have held any great part in their teaching. Their system must have been composed of a collection of processes and receipts which grew in number as the centuries passed away. There is nothing in the texts to show that these receipts were the property of any close corporation, but heredity is sure to have played an important part and to have made them, to some extent, the property of a class. Architects were generally the sons of architects. Brugsch has given us one genealogical table in which the profession descended from father to son for twenty-two generations. By help of the inscriptions he traced the family in question from the time of Seti I. to that of Darius the son of Hystaspes. But even then he may not have tracked the stream to its source. The rule and compass may have entered that family long before the time of Seti; their use may also have continued long after the Persian kings had been driven from Egypt. [Illustration] CHAPTER III. SCULPTURE. § 1. _The Origin of Statue-making._ The art of imitating living forms by means of sculpture was no less ancient in Egypt than architecture. We do not mean to say that it already existed in those remote ages when the first ancestors of the Egyptian people built their mud cabins upon the banks of the Nile; but as soon as their dwellings became something more than mere shelters and began to be affected by the desire for beauty, the figures of men and animals took a considerable place in their decoration. The oldest mastabas that have been discovered have bas-reliefs upon their walls and statues in their mummy-pits.
