Register or Login to view.I don't often respond publicly anymore, but recently my name has appeared in academic circles so, I will review some of my own published work as it might be relevant to this post. Much of my work since 1983, has been published through the Department of Anthropology at the University of Oregon, my geodesy field work, and associated cartographic maps, can be found in numerous occasional papers published by the Natural History Museum of the U of O. I began studying the VM in 1987 and was, at this time, employed as the Assistant Director of the U of O Map Library. As the AD it was my job to know all of these early works. By 1985 I was already familiar with the Catalan Map. That "mapa munde" was the first to employ the rose compass image. As the AD it also fell on my shoulders to peer review the work of other professional cartographers. (Note the Atlas Catalan is not the Mapa Munde. That map was found in the Hereford Cathedral school. It does, however, show the level of geographic knowledge and study in this region.)

The drawings on both 68v and 68r are not star charts. One of my specialties is archeoastronomy and I understand the use and development of star charts and images that date back 45,000 years. The images on these pages are instead, mechanical parts to an unnamed apparatus. I have built this apparatus and tested it in a real-world environment. Some of this work was published in the paper about Viking Sunstones through Academia.edu. DOC
