When the Duke of Athens made himself tyrant of Florence, King Robert urged him to take up his abode in this palace, as Charles of Calabria had done, and leave the Palace of the People to the Priors. The advice was not taken, and, when the rising broke out, the palace was easily captured, before the Duke and his adherents in the Palazzo Vecchio were forced to surrender. Passing along the Via Ghibellina, we presently come on the right to what was originally the _Stinche_, a prison for nobles, _in qua carcerentur et custodiantur magnates_, so called from a castle of the Cavalcanti captured by the Neri in 1304, from which the prisoners were imprisoned here: it is now a part of the Teatro Pagliano. Later it became the place of captivity of the lowest criminals, and a first point of attack in risings of the populace. It contains, in a lunette on the stairs, a contemporary fresco representing the expulsion of the Duke of Athens on St. Anne's Day, 1343. St. Anne is giving the banners of the People and of the Commune to a group of stern Republican warriors, while with one hand she indicates the Palace of the Priors, fortified with the tyrant's towers and battlements. By its side rises a great throne, from which the Duke is shrinking in terror from the Angel of the wrath of God; a broken sword lies at his feet; the banner of Brienne lies dishonoured in the dust, with the scales of justice that he profaned and the book of the law that he outraged. In so solemn and chastened a spirit could the artists of the Trecento conceive of their Republic's deliverance. The fresco was probably painted by either Giottino or Maso di Banco; it was once wrongly ascribed to Cennino Cennini, who wrote the _Treatise on Painting_, which was the approved text-book in the studios and workshops of the earlier masters.
