Here is some more of the original artwork, and some notes from the Time Treasure 3 document.
The Time Treasure 3 depicts the ages of man, and also relates to the element air and the 8-sided Platonic solid called a octahedron.
and the text on that floating octahedron decodes to something like “Air we all breathe air”.
The designer of the Time Trail added a preliminary stage to the more familiar Shakespearian seven ages of man, “The Foetus”, and suggests that the Air theme is fundamental to all eight ages:
Without oxygen from the air to breathe, our life ends and with it our perception of Time. From conception to death, our existence is nothing without air. Life’s many stages from foetus to old age are driven by a natural quest for air. Fresh air and exercise help us lead a full active life. The brain that provides us with our perception of time has the biggest demand for oxygen than any other organ of the body.
T3:7/8 Sixth age
T3:8/8 Second childhood
The decoding of the T3 series yielded the following text:
[L]ungs never full ensnare us in time's eight piece cage/ Entropy's aim shoots leptons in dancing cycles of light/ Nations reach out
and, since we have T1, T2, and T3, our results so far read thus:
Measure every heartbeat to count out our life's score Is "time to escape" meant to fire our coming age? Locked in seasons' bars swings pendulums's ceaseless claw Lungs never full ensnare us in time's eight piece cage Entropy's aim shoots leptons in dancing cycles of light Nations reach out
A substantial part of the T3 Time Treasure booklet is devoted to a long story about a giant egg timer and a King who was too fussy about his boiled eggs.
