Roman Dodecahedron replica

Print! Cut! Fold! Glue!

Dimensions for making a replica Roman Dodecahedron (3)

Let us prepare a copy of the Roman Dodecahedron of Jublains.
We can use the paper:
Une fouille en bordure des thermes de Jublains (Mayenne) : enfin un dodécaèdre en contexte archéologique !
Gérard Guillier, Richard Delage et Paul-André Besombes, at http://rao.revues.org/680

For the dimensions please see the image http://rao.revues.org/docannexe/image/680/img-16.png

Or print and cut

Dimensions for making a replica Roman Dodecahedron (2)

Let us suppose somebody wants to make a replica of a Roman dodecahedron,.
Here another recipe. Consider the image

Centered at the center of each face, draw a circle, which will be a hole. These circles usually have different diameters. Print and cut the image.
 If you want some figures, you can, for instance use the article by

Duval Paul-Marie. Comment décrire les dodécaèdres gallo-romains, en vue d'une étude
comparée. In: Gallia. Tome 39, fascicule 2, 1981. pp. 195-200, doi : 10.3406/galia.1981.1829

Here I reproduce an image.

You have the exact potions of holes.
According to the image of the dodecahedron, 1 is opposite 12, 2 opposite 11, 3 opposite 10, etc.

Here I am reproducing a table.

Here we have not the exact potions of the holes, but we have the diameters of holes on the opposite faces.
According to the image of the dodecahedron, 1 is opposite 12, 2 opposite 11, 3 opposite 10, etc.

Roman Dodecahedron of Kadath

The web site http://www.kadath.be/ is publishing the review Kadath. The site tells that it is based on the "projet KADATH". "Dans l’œuvre de H.P. Lovecraft, Kadath est la cité légendaire des Grands Anciens, symbole de l’origine des civilisations. Notre quête, appliquée aux réalités archéologiques, est de remonter à pareilles sources, en cherchant à déchiffrer l’empreinte que laissèrent les premiers civilisateurs, dieux et ancêtres présents dans tous les mythes et toutes les traditions."

At the link http://www.scribd.com/doc/116123429/The-Roman-Dodecahedron-of-Kadath

the reader can find a paper from Kadath, written by Pierre Méreaux-Tanguy discussing the Roman Dodecahedron as an optical instrument. For other reference on the Roman Dodecaedron see the papers: Ancient and modern rangefinders at http://arxiv.org/abs/1205.2078 and http://arxiv.org/abs/1206.0946

Cooking ... the brain

"Brains demand exceptional amounts of energy," says Ed Yong at Discover Magazine — energy that raw food simply can't provide. That's where cooking comes in.
Writes Yong:
Our ancestors overcame this constraint when they learned how to cook. Cooked food offers more calories than raw food, and is easier to chew and digest. These early chefs could gain more energy from the same amount of eating time. That, in turn, fueled more neurons and larger brains.

De bello Parthico

Roma. Anno 44 avanti Cristo, mese di marzo. Da un futuro lontanissimo in cui la scienza ha raggiunto vertici inimmaginabili, ma insanguinato da una guerra cruenta, appare nell'Urbe un misterioso personaggio. E' un viaggiatore del tempo dotato di straordinari poteri. Nessuno saprà mai qual è la sua vera identità, si fa chiamare Sesto Mercurio e con questo nome verrà ricordato negli annali dell'Impero. Ha una sola missione da compiere: salvare Caio Giulio Cesare dall'imminente attentato delle idi di marzo. ...
