In science they especially cultivated geometry, astronomy, astrology, and ‘alchemy,’ whose name betrays its origin. Their arithmetic taught decimals and duodecimals. Their mathematics arose from measuring fields and calculating the cubes of altars. They knew the precession of the equinoxes: Rodier (p. 31) considers that they learnt it from observing the equinoctial point and the rising of Sothis, the Tuth-star, ‘the axle of the skies,’ in the same zodiacal sign, and that the studies at Syene date from B.C. 17,932. They knew the motion of the apsides, and the solar and stellar periods; they invented latitude and longitude; they denoted by a cross the intersection of the solstices and the equinoxes, and they published annual calendars. In optics they invented the lens. They were not ignorant of the motive power of steam, and possibly the electric fish had taught them the rudiments of electricity. They were great in the mechanical arts. In medicine they dissected and vivisected: in agriculture they invented the plough, the harrow, the toothed sickle, the flail, and the tribulum; in carpentry the dove-tail; in ceramics the potter’s wheel, and in hydraulics the water-wheel. In gardening they transplanted full-grown trees. They made glass, porcelain, and counterfeit pearls and precious stones; and they used emery powder and the lapidary’s wheel. They spun silk, and knew the use of mordants for stuffs and dyes for hair. They made ‘babies’ (dolls) and children’s toys of clay, and they moulded masks of papier-mâché. In some points they were strangely modern. For hunting they wore dresses of ‘suppressed colour,’ not pink nor ‘rifleman’s green’: we are just beginning to find out our mistakes. They affected falconry, and played at the draughts which led to chess; and at _morra_, the Roman _micare digitis_. They sat on chairs whose shapes are like ours, not on divans nor on triclinia. In their house furniture they studiously avoided over-regularity; and Japan is now teaching England and Germany not to weary man’s eye by monotony.
