This is a very unusual, baroque style astrological chart. The chart illustrates good and bad periods of health or physical vulnerability in relation to the planetary alignments. It also illustrates the ancient Greek astrological concept of the climacteric years (annus climactericus). This seven year cycle was thought to be critical in a person's life. The tables on either side of the chart have columns of numbers corresponding to Motus Menstruus (the lunar cycle) and Motus Diurnus (daily motion of stars around the Earth).
