That the Egyptians excelled in science and art is evident from their monuments, paintings, and sculptures, whereon they are depicted. It is also proved by Scripture, which speaks of the “wisdom of Egypt” with reference to art; and from the fact that Egypt was deemed by other nations the fountain of arts and sciences, and that their philosophers were wont to resort thither to collect some of the “droppings of Egyptian wisdom.” According to Diodorus, all trades vied with each other in improving their own particular branch, no pains being spared to bring each to perfection. To promote the more effectually this object, it was enacted that no artisan should follow any trade or employment but that defined bylaw, and _pursued by his ancestors_. No tradesman was permitted to meddle with political affairs, or hold any civil office in the state, _lest his thoughts should be distracted by the inconsistency of his pursuits_, or the jealousy and displeasure of the master in whose service he was employed. They foresaw that without such a law constant interruptions would take place, in consequence of the necessity or desire of becoming conspicuous in a public station; that their proper occupations would be neglected, and many would be led by _vanity_ and _self-sufficiency_ to interfere in matters which were out of their sphere. They considered, moreover, that to pursue more than one avocation would be detrimental to their own interests, and those of the community at large; and that, when men, from a motive of avarice, engage in numerous branches of art, the general result is, that they are unable to excel in any. If any artisan interfered in political matters, or engaged in any employment other than the one to which he had been brought up, a severe punishment was immediately inflicted upon him.
