68r1 and 2

Another thought. The star map I generated had a rotation of about 35 degrees (I didn't measure it accurately). The rotation of the stars is 1 degree every 71.6 years, so 35 degrees would put it at about 490BC. Ptolemy in AD150 would have a rotation of 26 degrees. 1420 would make it 8 degrees. This assumes the Voynich manuscript and the modern map are lined up along the same principals. Any angular shift could also be explained by differences between the date within the year the maps are made.
