(Total life time)
Every day we have lived is one day less to live.
The clock in the middle represents life time which runs synchronously between the time that was lived and the time left to live. The row of plus signs moves towards the row of minus signs through the clock. The clock at 6 o’clock (= half the time of a total clock time) representing half the time spent.
The arrows on the left and right of the drawing run on both sides of the control panel towards the clock. On one side is a bed with baby representing birth and the beginning of the life time (time = 0) The celestial bodies represent sidereal time. At birth and depending on the alignment of the stars and planets, it has already been determined how long total lifetime will be. So the end on the other side of the control panel contains the sign of death (the XX stand for the time at the end of life and thus death).
On the left there is a large +1 which stands for a day lived.
On the right is a large -1 which stands for a day less to live.
The sum of the two times give us the TOTAL LIFE TIME.
