But I wonder if an internet search would bring up things like this:
Veice, Campo San Polo. Check out the pharmacy, look for an oval plaque on the wall to the right of the door. It reflects trademark infringement about four hundred years ago.
In San Marco, there was a well known and respected pharmacy, the Due Colonna, the Two Columns.
Pharmacy operators in San Polo opened a pharmacy, aloso called the Due Colonna, a clear infringement of trademark.
The Commune decreed this to be not proper, demanded the San polo guys changed their name,which they did.
To Uno Colonna e Mezzo, a Column and a half. You can see it on the plaque.
Also in San Polo, in the Sacristy of the church, a brilliant confronting Stations of the Cross by Tiepolo, the crucifiction told in fourteen frames. There is no Gentle Jesus Meek and Mild here, more a political prisoner being done to death. Also the ascention is a great piece, Jesus ascending, leaping towards the heavens. Worth the three euro admission.
Another one. Standing on the Rialto, look towards San Marco, to the building high on your left. You will see a golden head hanging from the side of the building. There used to be a famous pharmacy there, the Testa del Oro, the Golden Head. Sadly now it is just another shop selling the ususl stuff.
And yet another. At the Rialto fish market, at the Grand Canal end and outside, you will see a plaque on the wall listing the minimum size of various fish species allowed to be sold. Plaque dates from about 1910.
Also at the fish market, the side remote from the fruit and veg, outside, stairs lead upstairs. There are a pair of closed gates, wrought iron, bearing the inscription translated from Greek to Latin by Erasmus in the 16th century, “piscis primum a capite foetet”, (fish begins to stink from the head), a comment about the stench of corruption starting at the top.
The Rialto bridge took some four years to construct, and the merchants and moneylenders who were funding it (What news on Rialto, Shylock) started to get grumpy. The word got around that the bridge would not be finished until “the male member grew fingernails, and flames burst from the female equivalent”.
Antonio da Ponte, builder, had the last laugh, and as you face the bridge on the San Polo side, to your left on the building, you will see a pair of plaques, with said fingernails and flames. Never has been a good idea to insult civil engineers.
All little details, very endearing. Even guide books are mostly mute on such treasures.
