58 times, in which Aries and Taurus pass the mid-heaven; because, again, the prorogatory place was culminating.[171] In the same way, let the first point of Aries be descending[172]; so that the beginning of Cancer may occupy the mid-heaven, and the first point of Gemini precede the mid-heaven at the distance of 32 equatorial times.[173] Therefore, as the first point of Aries is on the west, and again distant six temporal hours from the meridian, let these six hours be multiplied by the seventeen times; which will produce 102, making the sum of the distance[174] of the first point of Gemini, at its future descension, from the meridian.[175] But, as the first point of Gemini, at its first position, was already distant from the meridian 32 times; which number 102 exceed by 70; it will consequently arrive at its descension after 70 times, the amount of the excess; in which space Aries and Taurus will have descended, and their opposite signs Libra and Scorpio arisen.[176] [167] By right ascension, as shown by the Extract, inserted in the Appendix, from the Tables of Ascensions in the Almagest.
