What is a synodic cycle?
- It is the latest craze in physical exercise. Instead of using two walking sticks as in nordic walking you use a specially constructed bicycle, the synodic cycle. The difference with a normal bicycle, other than the price (starting at €500,- for the basic model) is its construction. The synodic cycle has a combined prograde and retrograde motion that exercises every muscle in the body while riding it. It has different settings for a quick or slow synodic cycling tour.
- A synodic cycle has nothing to do with astrology or astronomy. It is the cycle of meetings by bishops of various Christian denominations, not always at the same time. The word synod is from the Greek and means ‘meeting’ or ‘conjunction’
- A synodic cycle is different for the outer and the inner planets. For the inner planets the only form of synod possible is the conjunction. For the outer planets the synod has both the conjunction but also the opposition. The synodic cycle shows when one of the inner planets is a morning or evening star.
- The synodic cycle is always with reference to the Sun. It is the cycle of conjunctions and oppositions (if an outer planet) to the Sun. It also contains the cycle of first and last visibility at sunrise or sunset. For ancient astrologers this first visibility was of great significance.
- A synodic cycle is the cycle of waking and sleeping, when you either nod off or nod on. It is closely related to the synapse, which is a refreshing sleep inbetween.
