《Tetrabiblos》Friends And EnemiesClaudius Ptolemy（Ashmand 英譯 1822）
And, should the signs, which operate travel, be themselves single in form, or should the planets, having dominion of them, be singly posited, the journeys will then take place after long intervals, and occasionally only: but, if the said signs be bicorporeal, or double in form or figure, travel will be constantly repeated and continued.
