Objects from the Regolini Galassi tomb

The Regolini Galassi tomb application was shown in Rome from the 15th of April till the 20th of July 2014 in the context of the exhibition Les Etrusques et la Méditerranée. La cité de Cerveteri/Gli Etruschi e il Mediterraneo. La città di Cerveteri, together with more than 450 masterpieces of the Etruscan culture.

This exhibition showed several precious objects belonging to the Regolini-Galassi grave goods, together with the Sarcophagus of the Spouses (from the Louvre), the sculpted group of Greppe S. Angelo, terracotta objects from the museums of Berlin, Copenhagen and the Vatican Museum, finds from the Pyrgi sanctuary and some of the most recent discoveries carried out in the urban area of Cerveteri, in the necropolis and in the surrounding territories.  The exhibition showed the relationships that Etruscans had in the Mediterranean area through the history of Cerveteri, one of their most important cities. This exhibition was curated by F. Galulier, L. Haumesser, P. Santoro, V. Bellelli, A. Russo Tagliente and R. Cosentino.

The exhibition has been jointly organized by Louvre Lens and Palaexpo, thanks to the collaboration between the Département des antiquités grecques, étrusques et romaines of the Louvre, the Istituto di studi sulle civiltà italiche e del Mediterraneo antico of the CNR and the Soprintendenza per i beni archeologici dell’Etruria meridionale.  It had already been hosted in the Louvre Lens from the 5th December 2013 till the 10th of March 2014.

2013 in review

5 Jan

The WordPress.com stats helper monkeys prepared a 2013 annual report for this blog.

Here’s an excerpt:

The concert hall at the Sydney Opera House holds 2,700 people. This blog was viewed about 16,000 times in 2013. If it were a concert at Sydney Opera House, it would take about 6 sold-out performances for that many people to see it.

The Etruscanning application at ArcheoVirtual

23 Nov

Every year, the Virtual Heritage Lab at CNR-ITABC organises the ArcheoVirtual exhibition at the Borsa Mediterranea del Turismo Archeologico and shows the best applications in archaeological visualisation.  This year, the V-MusT.net Network of Excellence, coordinated by CNR-ITABC, used the venue to organise two workshops on museum technology plus several other meetings.

One of the ArcheoVirtual stands that attracted the most interest was Etruscanning with the VR visualisation of the Etruscan Regolini-Galassi tomb. The application on display was the improved, second version in Italian.  We made a small video on how this second version of the VR application on the Regolini-Galassi tomb looks like.

Work continues to improve the digital museum objects through digital restoration and image based digitisation.  The Dutch version of this improved application will be installed soon in Amsterdam and Leiden.

Digitisation of museum objects

25 Aug

The digitisation of some museum objects from the Regolini-Galassi tomb has started on August 24.  The photographic department of the Vatican Museums has made extensive and specific photography that will allow us to create 3D models, that will be used in the exhibitions in Amsterdam and Leiden (Netherlands) from October 13 2011 onwards.

The objects were put on a turntable and in an object tent that allows to have a very even lighting on the objects.

As we want the 3D objects to look like new (as we reconstruct the tomb just after closure), most of the work goes into digital restoration of the objects, or by hand modeling based upon the existing or new photography, or by editing the digitised models (made by dense stereomatching of photographs).  The resulting 3D models will be optimised and visualised in real-time with special techniques to obtain a high degree of realism without an excessive amount of data.

Several objects were documented through the Object VR technique, by photographing the object while it is rotated on a turntable.  In the image below, the 6-headed lebes is recorded in 36 photographs with consecutive rotations of 10 degrees.  These images do not only provide a very detailed documentation of the object but allow also for future use on the internet or in multimedia systems in exhibitions.

The Etruscanning team is very greatful to the team of the Vatican museums for the excellent cooperation in this three day digitisation effort.

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).
