Life of Christ: Crucifixion (detail), 1304-06, Giotto di Bondone. Giotto's paintings are so visceral. I see the influence of the iconographic tradition without doubt, but the emotion that permeates his work is a wildly unexpected departure from the almost expressionless faces of that time period. I saw a phrase last night that is expressed here - art that is radically idiosyncratic. So ancient, so modern, so compelling.
