In addition to this meeting with Monti, the Pope also agreed to meet with Italy's president Giorgio Napolitano. In fact, they are the only meetings the Pope added to his schedule after announcing his resignation. The Vatican says it's a way to show his gratitude to Italy and vice-versa.
Mario Monti thanked the Pope for the eight years of his pontificate. As a gift, he gave Benedict XVI three pens, colored red, white and green, which represent the colors of the Italian flag. The Pope gave him a framed image of the Vatican Gardens.
