Since my last post, the team of the Etruscanning 3D project had had a new meeting and the results of the restoration process had been discussed. Archaeologists focussed their attention on the cinerary urn.
By comparing coeval examples of urns, it is immediately evident that they all have four support structures at the corner of their basis.
For this reason it is highly probable that also the Monte Michele urn had those kind of supports, even if no traces of them had been found during the excavation.
In order to determine their appearance, we analysed the structure of the whole box. We came up to the conclusion that it has to be similar to the one of the Falerii Veteres urn, but hidden behind the bronze plates. Moreover, this theory explains very well why no traces of the support structure are visible on the bronze bottom of the urn. We can suppose that the iron structure of the urn surrounded it, as it is shown in this picture.
Thanks to the help of archaeologists, we come up to this new 3D reconstruction of the Monte Michele urn.
