Pope Francis Portrait In Italian Field, 'Love Liberates,' Made By Dario Gambarin's Tractor (VIDEO)

Dario Gambarin uses an unusual medium for his art -- a field in Castagnaro, Italy. His latest work is a 328-foot portrait of Pope Francis, created in six hours with a tractor.

Gambarin says he "uses his plough as a painter would a brush," according to The Telegraph. He doesn't measure the field before beginning, but uses his instinctive sense of proportion to use the field as his canvas.

He created the portrait of Pope Francis titled, "Love Liberates," after the pope's announcement that he would lead an international, interfaith, day of fasting and prayer for peace in Syria on September 7. The farmer was moved by the call for peace and wanted to "contribute something to the pontiff's appeal."

This isn't the first time that Gambarin has gotten political with his plow. He created a portrait of President Barack Obama in July 2009 to coincide with his visit to Italy for the G8 summit, and he's also featured Nelson Mandela on his field. The images only last a few days, as he must work in between the harvest of one crop and the sowing of a new one.
