NICAS Colloquium online

8 October @ 12:00 pm - 1:00 pm CEST

 

We are pleased to announce a new, online edition of the NICAS colloquium on Thursday 8 October 2020 from 12.00 to 13.00 hrs. The colloquium will take place online through Microsoft Teams. By clicking on the following link, the meeting will open in your browser.

 

Throughout the year, NICAS organises a bi-weekly Colloquium consisting of two short research lectures. It provides researchers with the opportunity to present ideas for, updates on or results of their activities. The NICAS Colloquium allows people to stay informed on a regular basis about the latest developments and results of research and to exchange information and expertise.

 

 

The chair of this colloquium will be Guus Verhaar (Rijksmuseum)

 

The presenters are:

 

Francesca GabrieliRevealing molecular composition of paintings by Reflectance imaging spectroscopy (RIS)

 

Abstract:

Reflectance imaging spectroscopy (RIS), or also known as reflectance hyperspectral imaging, has been developed in remote sensing field and applied to the study of works of art starting from beginning of 2000s. Complementarily to the elemental information gained through the MAXRF imaging technique, RIS provides molecular information and allows for the identification and mapping of chemical compounds present in the artworks. RIS is usually performed from the visible near infrared (NIR) to the short wavelength range, from 400 to 2500nm, and has been used for identification and mapping of pigments and binders on easel paintings and manuscripts. This presentation will show the use of Reflectance imaging spectroscopy, complementarily to MA-XRF, to investigate the painting technique of Peter De Hooch (b.1629 – d. after 1684) in order to understand how the artist created his iconic, intimate depictions of 17th century everyday life.

 

Bio:

Francesca Gabrieli is a Post Doc at the Science department of the Rijksmuseum. She graduated in Physical Chemistry and then obtained her PhD in Chemical Science applied to cultural heritage at the University of Perugia. She obtained a postdoctoral position in imaging science at National Gallery of Art in Washington DC, USA, where she learnt and developed reflectance imaging techniques applied to the study of many art objects. She is now responsible for the Reflectance imaging spectroscopy at the Rijksmuseum and for Operation Night Watch.

 

 

 

Elke de BoerForensic approach to the authentication of the Casimir objects of the Rijksmuseum

 

Abstract:

Ernst Casimir and his son Hendrik Casimir I were Dutch stadtholders in the 17th century. These men were important military leaders in the Eighty Years War for independence of the Dutch Republic and are ancestors to the current Orange Royal Family. Both men were shot on the battlefield, Ernst was shot through the head while Hendrik was shot in his lower back. The Rijksmuseum has several items belonging to these men in its collection, namely the hat of Ernst Casimir and a shirt and buff coat of Hendrik Casimir I. These objects were allegedly worn by the men when they were fatally injured. Authentication of these objects has been based mainly on archival references, while the Casimir Project focuses on trace analysis or forensic evidence to aid the authentication process. In this presentation, I will demonstrate how SEM-EDX and MA-XRF were used to interpret forensic evidence on cultural heritage.

 

Bio:

Elke de Boer is a Master student at the Science department of the Rijksmuseum doing her research project about the Casimir Project. She graduated in Bio-Pharmaceutical Sciences at Leiden University and continued in the Forensic Science master programme at the University of Amsterdam. Currently she is applying the forensic approach on the Casimir objects, where she is using SEM-EDX, MA-XRF and  bloodstain analysis to validate the 300 year old objects.
