Desperately seeking Da Vinci

Scientist Maurizio Seracini believes there is s lost Da Vinci painting hidden inside a wall in Florenceā€™s city hall, and he wants to use high tech techniques to find it. The Battle of Anghiari, the largest painting Leonardo ever undertook, was never completed, but was studied "as an unprecedented study of anatomy and motion."

Seracini is using lasers, radar, ultraviolet light and infrared cameras to map the wall of the room where the painting is supposed to have been displayed. The painting was lost in 1563 when the walls were covered by military frescoes. Experts believe, however, that they know the wall where it was painted, and now Seracini hopes to find remnants of the lost work.
