Did Florence receive a gift from Pisa

Did Florence receive a gift from Pisa
 

The copy of the "Gates of Paradise" of the Baptistery obviously catch our attention but the two porphyry columns situated next to the door represent a particular gift Pisa made to Florence, its fierce enemy. Why? Because  Florentine population  helped Pisa  to fight against Saracens in the Balearic Islands in 1117. These columns were part of the booty Pisa sacked during the war with gold, silver, precious stones, marble objects, carpets, cloths. The legend  said that the columns had a particular characteristic: they could reflect the faces of unpunished people, killers who had committed a crime and they were still free.
Florence moved the two columns from Pisa on a boat on the river Arno and the city feasted their arrival. Florentine realized very soon the columns weren't glossy and they didn't have the magic characteristic. It was true! Pisa in fact secretly set up a fire the night before the boarding to warm up the columns. Their brilliance disappeared forever! The Pisan gift became a trick and for this reason the bitterness between the two cities increased very much during the following years.
As the saying goes: " Florence is blind and Pisa is a traitor" Event the famous poet Dante Alighieri in his Comedy says Florence is renowned to be a too-confident city. Read the passage of the Hell (XV, 67)!
