TWO:There is also a distinction between machine and hand cutting that may be noted. In machine cutting it is performed in true geometrical lines, the tools or material being moved by positive guides as in planing and turning; in hand operations, such as filing, scraping or chipping, the tools are moved without positive guidance, and act in irregular lines.Lathes in common use for machine fitting are screw-cutting engine lathes, lathes for turning only, double-geared, single-geared, and back-geared lathes, lathes for boring, hand-lathes, and pulley-turning lathes; also compound lathes with double heads and two tool carriages.
TWO:Besides this increasing reverence paid to the deified mortals of ancient mythology, the custom of bestowing divine honours on illustrious men after or even before their death, found new scope for its exercise under the empire.232 Among the manifestations of this tendency, the apotheosis of the emperors themselves, of course, ranks first. We are accustomed to think of it as part of the machinery of despotism, surrounded by official ceremonies and enforced by cruel punishments; but, in fact, it first originated in a spontaneous movement of popular feeling; and in the case of Marcus Aurelius at least, it was maintained for a whole century, if not longer, by the mere force of public opinion. And many prophecies (which, as usual, came true) were made on the strength of revelations received from him in dreams.356 But a much stronger proof of the prevalent tendency is furnished by the apotheosis of Antinous. In its origin this may be attributed to the caprice of a voluptuous despot; but its perpetuation long after the motives of flattery or of fear had ceased to act, shows that the worship of a beautiful youth, who was believed to have given his life for another, satisfied a deep-seated craving of the age. It is possible that, in this and other instances, the deified mortal may have passed for the representative or incarnation of some god who was already believed to have led an earthly existence, and might therefore readily revisit the scene of his former activity. Thus Antinous constantly appears with the attributes of Dionysus; and Apollonius of Tyana, the celebrated Pythagorean prophet of the first century, was worshipped at Ephesus in the time of Lactantius under the name of Heracles Alexicacus, that is, Heracles the defender from evil.357
