"One... characteristic of medieval space must be noted: space and time form two relatively independent systems. First: the medieval artist introduced other times within his own spatial world, as when he projected the events of Christ's life within a contemporary Italian city, without the slightest feeling that the passage of time has made a difference, just as in Chaucer the classical legend of Troilus and Cressida is related as if it were a contemporary story. When a medieval chronicler mentions the King... it is sometimes difficult to find out whether he is talking about Caeser or Alexander the Great or his own monarch: each is equally near to him. ...the word anachronism is meaningless when applied to medieval art... in Botticelli's The Three Miracles of St. Zenobius, three different times are presented upon a single stage."
