I'm thinking also of the Gobekli Tepe structure being of a similar type, as the carvings on the pillars there may have linked constellations to local fauna, and perhaps the Newgrange symbols as well. <br />http://www.pineroloplay.it/wp-content/uploads/2014/02/gobekli-tepe.jpg <br />http://www.kerryexperiencetours.ie/wp-content/uploads/2014/10/Newgrange-Ireland.jpg<br /><br />Ok, that was fun, but now back to your Interlacing Theory. (hehe)<br /><br />Note: Regarding your observation that some "square" based huts weren't very square: in the Malay Archipelago by Alfred Wallace, he mentions that on some islands people constructed square huts without diagonals, instead inserting very crooked poles which gave similar support, though eventually the huts would be windbeaten and begin to tilt precariously. I don't think the postholes would indicate this arrangement.DDedenhttps://www.blogger.com/profile/10033851770461086341noreply@blogger.comtag:blogger.com,1999:blog-2357316514436369105.post-22178455121179599012016-02-09T08:53:34.038+00:002016-02-09T08:53:34.038+00:00DDeden - planning may not be an issue, as this wou...DDeden - planning may not be an issue, as this would inevitably be a temporary structure, Pygmies living in areas where it does not snow for obvious reasons. <br />Geoff Carterhttps://www.blogger.com/profile/01111820035762957610noreply@blogger.comtag:blogger.com,1999:blog-2357316514436369105.post-54758679771513903632016-02-09T08:49:49.677+00:002016-02-09T08:49:49.677+00:00In a later post I will address what this is all ab...In a later post I will address what this is all about in more technical terms, this is really just a teaser to show I am still at work.<br /><br />However, more generally, the issue of taper is an interesting one, as it impacts model building in several significant ways.<br />I used to make components by starting with a tapering trunk [based on yield tables], which is fine for posts, but becomes problematic for horizontal components where one surface has to “level”.<br />There is also an important observation about this class of structure; postholes decrease in diameter towards the centre, which implies that ties were arranged with taper towards the middle. Any system of timber architecture has to deal with this issue, but for modelling one has to assume that horizontal roof components are level, thus I use uniform components for this type of work. This does not have to apply to ties that could be left in the round. For practical purposes one has to theorise the use of boxed heart from very large trunks as the main source of horizontal timber.<br />Geoff Carterhttps://www.blogger.com/profile/01111820035762957610noreply@blogger.comtag:blogger.com,1999:blog-2357316514436369105.post-83151459463176888292016-02-09T00:36:24.346+00:002016-02-09T00:36:24.346+00:00It may be indicative of (something or other) that ...It may be indicative of (something or other) that the height difference between the top surfaces "front" trilithons and the taller ones surrounding the Altar Stone is pretty much the thickness of the butt end of a decent length of oak tree (if we're piling up our Spillikins like <i>that</i>, just to see what happens.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2357316514436369105.post-79906020518550403972016-02-04T22:40:35.100+00:002016-02-04T22:40:35.100+00:00Excellent idea!

It would give 3200 square feet of roof per little dome; you would need 8 tons [American] of thatch per dome, but if can bend 40 ' trees it would probably be OK - till it snowed. <br /><br />I' ll start making enquires about planning permission right away!<br /><br />[a single dome made from bending bending 140/ 150' saplings is about 51,000 square feet in area, which might weigh a quite bit].Geoff Carterhttps://www.blogger.com/profile/01111820035762957610noreply@blogger.comtag:blogger.com,1999:blog-2357316514436369105.post-85218655472471265932016-02-01T23:29:54.197+00:002016-02-01T23:29:54.197+00:00Well, I'm not claiming Stonehenge was domed, b...Well, I'm not claiming Stonehenge was domed, but it certainly could have been, without technical difficulties nor giants. A portable climbing scaffold, lots of coppiced & trimmed flexible branches and binding cord, and a crew would probably get it done comparatively swiftly. <br /><br />A Pygmy lady pairs each wicker post with the opposing one, at the apex, bending and binding them (about 4.5'/1.5m) to make one long arched pole, so a sum of 5 interwoven structurally, with a pentagon sky-window, then interweaves additional twigs to make a latticed dome overlay, then inserts leaves around in a coil to waterproof it. Takes 2 hours, one if hurried, and helped by a friend.<br /><br />The length of a "pole" from posthole to posthole would be: ?<br />Multiply by scale factor: ?<br /><br />Without the leaf shingles, the lattice sky grid, with an additional fine net-grid of flax thread, would provide an excellent observatory, cosmic movements and supernova identified by an arm-chair scholar to the nearest inter-net position.<br /><br />Want me to build one?

I'ven't any gold, so perhaps some donation requests to financial giants would be necessary... ?DDedenhttps://www.blogger.com/profile/10033851770461086341noreply@blogger.comtag:blogger.com,1999:blog-2357316514436369105.post-54807802912590574512016-01-31T21:55:50.956+00:002016-01-31T21:55:50.956+00:00Hi

His goes to a point and looks like a wigwam.<br />http://www.stonehenge.tv/roof.html<br /><br />Couldn't it have been open at the top, like the Pantheon?<br /><br />Apart from the little purple sketch indicating a ridged circle around a peak, it is hard to visualise your idea. Is that complication of poles the actual roof shape, or just a basis supporting a ridge somehow? Are the poles actually plaited, (or jointed) consistently over and under,like the Celtic interwoven designs or a basket,forming some sort of self supporting mat at an angle to the ground? Is the centre open or is there a roof over that, supported somehow on the lower level roof? How about a nice dome? No glass for windows? Thatch or shingle or slate roof? Birds flying through or nesting inside? The ancestors of your cat might have enjoyed chasing birds and mice there, if they'd got there early enough!<br /><br />On another topic, did I correctly see a comment on one of your older threads, suggesting that Seahenge is a hoax?
