I think so, too, Aine.

The inundation animations used for the BBC documentary, 2002 I think, were done at Durham University by Glenn Milne. In the following YouTube clip (the middle link actually) you’ll see the land build animation used that closely follows Glenn Milne’s (in lab) calculations at the very beginning. It was edited to more closely portray actual Earth topography – note the western expanse of the British Islands. It’s actually an entertaining example as well as remaining video that covers other things in his printed books.

{Special note:: : be mouse click ready and quick at the beginning of play or you’ll miss the land build}

The first link [based on his “Heaven’s Mirror” book] is a video production that preceded Underworld. Have the VHS – wish I’d have gotten the DVD’s. The books are great and have many resources listed in the bibliography for follow up, reading, and checking, which I do. I just happen to be a long time advocate of earlier civilization’s, too, and now augment my resources with Graham’s hard work and earned materials to check on other bits and pieces to help support hypotheses.

. . . The maps indicating Hy-Brasil as shown on the Dulcert portolan (historical book of sailing directions and charts that describe harbours and coasts), on the Catalan Atlas of AD 1375, and Ptolemaeus Argentinae of AD 1513, indicated in “Underworld: The Mysterious Origins of Civilization” (pages 501-502) by Graham Hancock, show variations of Hy-Brasil contours and slightly different main islands associated with it along with different sighting references as well as languages. Dates of the maps do not show longitudes – as you mentioned early on, longitude didn’t come about until centuries after the first three maps above. The Bathymetric map shown with them on page 502 is state-of-the-art at the time of this volume printing (2002) and shows Hy-Brasil and Porcupine Ridge and Bank between 40 and 200m below sea level. Close to current readings in an earlier map reference posted in this thread by Carolb.

At the projected Last Glacial Maximum (LGM), estimated at 21,000 years ago, 600 square kilometres or more, of the Porcupine Ridge and Bank would have been exposed. However, the estimated margin of error of inundation is not given for the zoom and detail.

By the way, one hypothesis I’m toying with is that those myths and legends about Hy-Brasil, HyBrazil, Brazil, Brasil, or which ever, is that they might have begun with one or more of those early maps in the early Gaelic language of the Irish Celts in the 1300’s. There are other things such as that Porcupine Ridge and Bank and the rest of that western coastline potentially running all the way up to Callanish, Scotland, where those stones exist – They have an interesting tale or two surrounding them – possibly during LGM or 21,000 years ago.

They’re an interesting bunch as they seem to incorporate two astronomical settings – one for the Sun and one for the moon, its “Nutation” cycle every 18.6 – 19 years. Nutation is an influencing effect that causes a swaying or nodding motion in the axis of rotation of the Earth, in this case. You probably know about the precessional wobble of Earth, every 25,920 years or so, usually rounded to 26,000 year cycle and the axial rotation, but there’s at least a significant third wobble caused by the moon’s orbit around Earth. It’s an 18.6 – 19 year wobble of the Earth already rotating on its axis while in orbit and in its slower precessional wobble. There’s also what’s called a ‘BaryCenter’ motion, but that’s a lot more explaining . . . Lots of local moving around astronomically for ignorant cave people to negotiate measurements and placements of very large stones in circles unless they were and are mischaracterized . . . I believe that they were and still are mischaracterized . . . They’re more likely the fragmented and missing ancient civilization Graham Hancock has been writing about. . . Cheers
