Hunebedden (Dutch dolmens) in proportion
About orientation patterns with hunebedden (in European context)
This websites is ’under construction’ continuously.
New information is added and existing insights are worked out further or get outdated.
Mistakes are rectified. This page offers an overview of all of the changes.
- On the page Elliptical mounds in extention to those of Mecklenburg also the mounds of Schleswig-Holstein have been processed now (all from the atlas of Sprockhoff).
A new type is added: the double circle.
- Reorganisation of the pages
- D22 and enlarged dolmens is called Orientation grid now
- D13, D21 and D22 is called Parallel orientation lines now
- Alignment on alpha Crux is called Alignments now
- D30, D40 and Goseck is called Elliptical mounds now
- Math in ancient times is called Geometry in ancient times now
- General distribution is dropped
- The instruments used is added
- Measurement of groundplans is added
- Measurement through ’gaps’ is added
- Revision history is added
- The pages Orientation grid and Hunebedden with satelites are appended with new insights.
The pages Alignments and Elliptical mounds have been revised completely.
- In the complete text the word porportional grid was replaced by the word orientation grid.
The term ’proportional grid’ is tied up closely with the searching for geometrical shapes,
while an orientation line in a grid doesn’t need to be part of such a shape at all.
- Page Geometry in ancient times, paragraph 6
Appended a discussion on Plimpton 322.
This old Babylonian clay tablet is placed in the same tradion as Plato’s method of finding right angled triangles.
- Page Geometry in ancient times, paragraph 13-15
Appended a discussion on the clay tablet YBC 6967 and the so called geometric algabra of Mesopotamia.
- Page Alignments, paragraph 18
The tempory hypothesis for a possible association of the Funel Beaker culture with α-Crux has been revised a little.
In the previous version it was supposed, that the Funel Beaker culture ceased to exist shortly after the KAK came up.
But Funel Beaker and KAK appear to have been contempory cultures for quite a long time.
Additionally, also in Soutern France alignments at α-Crux seem to be a possibility,
so that it’s more obvious to suppose an association with the megalith building directly then via a culture.
- Page Alignments, paragraph 5 and 6
Whereas the orientation lines at 167° in D21 were seen as contradicting with an alignment at α-Crux formerly,
now it appears from pictures of the excavation that this doesn’t need to be so.
α-Crux rose at 164° indeed, when the hunebed was built, but there is a good chance that the lines got reorientated a few degrees afterwards.
- Page Condition of the hunebedden, final paragraph
Matrix usability of the side stones has been dropped.
It became too much to give a complete overview of all of the megalithical monuments of this website.
The relevant information is presented in its context now.
- Page Elliptical mounds, paragraph 3
The mound of Spr. 340 is no longer typified as an ellipse with the proportion 8:15 but with the proportion 1:2.
Since the mounds in the atlas of Sprockhoff have a general deviation of a few decimeters, both shapes can’t be distinguished.
Although the mound has been drawn as an 8:15-ellipse, the most straightforward shape should be prefered.
- Page Hunebedden with satelites, paragraph 6
1) At first an univocal orientation at 140° was supposed. This can’t be advocated any longer.
Renewed understandings point at a double orientation at 140° and 143°.
It is possible that one orientation was transformed into the other at some moment, but this can be proofed hardly.
2) Hunebed D8 was compared to the central hunebed D25 near Bronneger.
It’s a little premature to typify D8 as a central hunnebed only on the basis of some orientation lines at 117° and 140°.
Recently it appeared that hunebedden without satelites can have orientation lines at 117° and 140° also.
- Page Orientation grid
To the hypothesis of the orientation grid that of an initial grid has been added.
By handling the intial grid as an orientation guide for the orientation grid, it appeared to be possible to systematize the so called mirroring around south.
- Page Geometry in ancient times, paragraph 9
C:B=(D+B):C becomes C:A=(D+A):C
- Page Orientation grid, paragraph 11
Dolmen G5 near Heveskesklooster doesn’t stand at 43° but at 143°.
Therefore the comparision to the orientation grid of D22 should be withdrawn.
