(ANSA) Pesaro, February 10 - A lost portrait attributed to
Leonardo da Vinci was already examined in 2013 by top Italian
art expert Carlo Pedretti who declared it then an authentic work
by the great Renaissance artist.
Pedretti's verdict on the portrait of Mantua Marchesa
Isabella d'Este was published exclusively by 'Sette,' the colour
magazine published by the Corriere della Sera newspaper.
Pedretti recounted the recent whereabouts of the painting
and published the results of a Carbon 14 test that turned out
95.4% positive.
Swiss police say the 61cm-by-46.5cm work was in the vault
of a Lugano-based trust.
The painting has been ascribed to Leonardo on the basis of
fluorescent analysis dating it to the first decades of the 16th
century, they said.
Further tests will now be carried out to clinch the
attribution.
Police are probing unnamed persons for illegally exporting
art works and for insurance fraud, they said.
