Here two possible digital "restorations" - that is, restorations made virtually on images - are shown of a marble bust of Julius Caesar, which is exhibited by the Rijksmuseum van Oudheden, Leiden.
Since the face of the Leiden marble bust, that you can see in the following image on the left, is damaged, we have to use the face of other marble busts representing Caesar.
The bust as it is is given on the left (Courtesy: Rijksmuseum van Oudheden, Leiden).
In the middle, the Leiden bust is digitally rstoerd using the face of the Tusculum bust. On the right you can see my lifelike rendering of the bust. Actually, the bust is one of two marble heads of Caesar that we can see at a page of the Rijksmuseum van Oudheden. It is the national archaeological museum of the Netherlands, located in Leiden.
However, we could use also the Chiaramonti Caesar tor estore the Leiden bust. Here the result.
