Recovered after Napoleons Italian art raids only to be slashed into 32 pieces by Austrian soldiers during the 1848 First Italian War of Independence, Paolo Veroneses banqueting painting for the monastery of the Madonna of Monte Berico in Vicenza has had a turbulent conservation history.

The Feast of Saint Gregory the Great (1572) depicts Pope Gregory I dining with a dozen poor pilgrims, including Jesus in disguise at his right-hand side. It is the only one of Veroneses series of monumental supper scenes still displayed in its original setting, the friars former refectory. There it will be analysed and cleaned from September to early 2021, in a restoration sponsored by the Italian banking group Intesa Sanpaolo. The bank describes the collaboration as a “birthday gift” to the city of Vicenza, where Intesa Sanpaolos art conservation programme, Restituzioni, was launched in 1989.

Veroneses painting technique “has not been studied in this pure way before”, says Valentina Piovan, the conservator overseeing the treatment on behalf of the local heritage authorities. The battle-scarred 39 sq. m canvas will this month be removed from the wall so specialists can work on it.

An initial analysis in 2017 revealed a “thick layer of discoloured varnish” which currently “compromises the integrity of the entire depiction”, Piovan says. But before the surface dirt and old varnish can be cleaned away in the new year, her small team will use non-invasive infrared and ultraviolet imaging to reconstruct the phases of Veroneses creative process.

X-ray fluorescence and gas chromatography will further help conservators understand the chemical composition of the pigments, binding agent and “mestica” (primer), used by the artist.

A key challenge will be distinguishing between Veroneses hand and the work of the paintings past restorers: Antonio Florian in 1817, Andrea Tagliapietra in 1858 (financed by the Austrian empRead More – Source
