| When was the Phaistos disc made? Probably about 1700 BC they say. We must
also remember the effects of the precession
of the equinoxes.
26000 years correspond to 360o and that corresponds approximately to 360 days. Winter solstice in 1700 BC can be calculated from this and the fact that it is situated on 21st of December in the year 2004. The precession has moved winter solstice (and the rest of the cardinal points) against the yearly course of the sun. (2004 + 1700) / 26000 * 360 = 51 days. When the Phaistos disc was made the cardinal points were located 51 days later than they are today. E.g. was winter solstice not in December but in the beginning of February. The rongorongo tablets perhaps were written some 150 years ago. That means we should think about a similar correction with 2 days.
