《Tetrabiblos》The PlanetsClaudius Ptolemy（Ashmand 英譯 1822）
Each of these quadrants contains certain parts, which, in comparison with its other parts, lie more contiguous to the middle of the earth; and these parts, in respect of the quadrant to which they belong, have a situation opposite to the rest of that quadrant, in the same manner as that quadrant itself is situated in regard to the rest of the earth.
