The ephemeral passage of a planet over the place of any Significator, moderator or planet, or any point where it forms an aspect thereto, whether in a radix, progressed, Solar Revolution or Horary Figure. Transits are taken from the ephemeris for the current year. Generally speaking the passage of the benefic planets over, or in aspect to, the radical and progressed places of the several Significators is favorable; of the malefics unfavorable.
Kuno Foelsch, Ph.D., in his work on Transits, which actually treats of the Solar Revolution, concurs in the suggestion that during the Middle Ages it became necessary to devise some system of approximating future conditions, for the reason that Ephemerides calculated for years in advance were not then obtainable. Speaking of Transits, he expresses the confident belief that "other methods will eventually disappear, especially those which are dependent upon hypothetical elements which have no connection with the actual astronomical positions of the planets as recorded by scientifically operated observations."
