The Regolini-Galassi tomb digitised

19 Jul

Although the Regolini-Galassi tomb yielded one of the most amazing collections of Etruscan objects, which are on display in the Vatican Museum, the tomb itself is currently not accessible to the public.

In June, CNR-ITABC made a laser scan of the Regolini-Galassi tomb.  A ‘time of flight’ Riegl Z390i laser scanner was used.  The 3D model is built of measurements about 6 mm apart on the surface of the tomb, with an accuracy of maximum 3 mm.

Here are some first results, showing only the shape of the tomb.  Currently the photographs of the walls are being mapped onto this shape, yielding  a photorealistic visualisation of the tomb very soon.

The tomb however has been restored significantly, and part of the roof of the cella had collapsed (as can be seen form the photograph below and from the previous post).

An earlier survey of the tomb by Malgherini also shows this damage in the cella.

Currently, there are several large stones inside the RG tomb.  We will check if these stones are part of the separation wall between cella and antechamber (the so-called window).

As can be seen from all of these images, only a small part of the antechamber of the tomb has a horizontal floor, most of the antechamber and the dromos (entrance part) have a significant slope.   Hence, the question that arises is if this slope is original or if there were stairs ending in a horizontal or faintly sloping floor.  By using ground penetrating radar (also called geo-radar), CNR-ITABC hopes to solve this issue soon.

After the excavation in 1836, the tomb was left open, without any maintenance or protection.  The image below shows the situation in 1838, as drawn by Mrs. Hamilton-Gray during her visit of the tomb (as described in her book Tour to the sepulchres of Etruria in 1839, published in 1843).
