A medieval mural in the town of Massa Marittima in Tucany, Italy, is causing controversy and amusement: the 12th century fresco, first uncovered only a few years ago, depicts a tree whose "fruits" are very unusual: its branches are filled with phalluses; below, a group of women are stretching their arms up to pick them.
There are discordant theories on the meaning of the mural: a) a fertility symbol of pagan inspiration or b) the earliest example of a political poster by supporters of the papacy against supporters of the emperor.
