Two statues wear a turban on the head, while a third, placed on a projecting corner of a house, has a metal nose, prosthesis added between 800 – 900, and carries on his shoulders a heavy burden that is engraved on the name "Rioba."
These statues represent the Moors, The brothers: Rioba, Sandi e Afani, whose names are inscribed above their heads who fled from the Morea (Greece) in 1112 for political disagreements. These were traders in spices and fabrics, and once you are in Venice gave it the name "Mastelli or Mastella." Over the years we have asked who represented the fourth statue: most likely is the servant of the three brothers, the same as that depicted in the frieze of the facade of Palazzo Mastelli, while leading a camel. This statue is placed in a niche in the fifteenth-century home of the famous painter Tintoretto (his father was a cloth dyer). On the front there is a large relief depicting Hercules with a club, placed there by the artist.
One of the three statues has a nose rusty and plays the 'Signor Antonio Rioba' which served as a spokesman of the Venetians when it came to criticizing the Republic.
