 Professor Seracini has studied over 4,300 works of art, most notably Leonardo Da Vinci’s lost mural, the “Battle of Anghiari” and “The Last Supper”, Boticelli’s “Allegory of Spring” and Carvaggio’s “Medusa”.He used high-frequency, surface-penetrating radar to locate the painting behind Vasari’s “Battle of Marciano in Val di Chiana”, forming the basis for the new technology that Professor Seracini would pioneer.Professor Seracini’s theory was confirmed by an investigation authorized by the city council of Florence and the Italian Minister of Culture at the time, demonstrating the efficacy of his methods.
