While on the plane, she searches the laptop further and discovers that the amphora from Alexandria was found in a river in 1477 AD and that it was going to be sold by an Arab to a merchant in Florence. She then falls asleep and dreams of being in medieval Florence watching the events of the transaction. The Arab, after sending the amphora to the merchant, gets caught by guards who were paid by black-robed men. Nina frees him and follows him to the merchant, who apparently is Leonardo Da Vinci. Da Vinci hides the scroll because it contains a solution to a mathematical problem by Archimedes and he doesn’t want it to fall into the wrong hands. Nina finds the coded scroll and she discovers that Da Vinci hid Archimedes’ solution behind his painting “Madonna Benois”, just before the painting was sold to Lorenzo de Medici. She wakes up, before she can follow de Medici, by black-robed men who entered her dream and finds out that the painting is currently in an exhibition in the Palace of Fine Arts in San Francisco and she plans to meet the restorer Michael Anderson there (who also Max was going to meet). Meanwhile, all this time since she left Berlin, she is continuously spotted from a satellite.
