Cimabue and Giotto, the Bundesbank and the ECB: an analogy?

Cimabue is defined by the Encyclopaedia Britannica as “the last great Italian artist in the Byzantine style”, while in the web-site of the Louvre one reads that Giotto "has been seen down the centuries as the instigator of a painting revolution without precedent since ancient times". Dante Alighieri in his Divina Commedia so defines the relationship between the two painters: “Credette Cimabue ne la pittura tener lo campo, e ora ha Giotto il grido, 
sì che la fama di colui è scura”, which can be translated in English as “Cimabue thought to hold the field in painting, and now Giotto hath the cry.”
