In 1595; Grand Duke Ferdinand I (Ferdinando de`Medici; 1549 - 1609; Grand Duke 1587 - 1609) comissioned Carrara based sculptor Giovanni Bandini (ca. 1540 - 1599) to built a life size statue to honour himself; the Grand Duke; and the victories of the military order of the Knights of St. Stephen (Italian: Ordine dei cavalieri di Santo Stefano) against the North African pirates and the Ottomans. In 1601; the statue of marble from Carrara arrived in Livorno and was installed at Livorno Harbour. In 1617; under the rule of Grand Duke Cosimo II de`Medici (1590 - 1621; Grand Duke 1609 to 1621); the marble monument was erected; by Taddeo di Michele; a scholar of Bandini. In 1621; sculptor Pietro Tacca (1577 - 1640); the most famous scholar of Giambologna; got the contract to add the four bronze statues representing "Moorish" slaves to the monument. He finished his work; in 1626. The four statues show three prisoners and slaves from North Africa and the Ottoman Empire; while the fourth slave and prisoner is clearly of subsaharian African origin. Sculptor Pietro Tacca discovered the images in the prison of Livorno; the Bagno dei forzati; which was originally at nowerdays Palazzo del Governo (government palace) and housed up to 2;000 prisoners. As well; it was a slave market. Later on; these prisoners and slaves were moved to the Old Fortress (Fortezza Vecchia) of Livorno. The three "Moorish" slaves are known as Morgiano; who is the youngest of all; looking into the sky and most probably of Greek or Ionic origin; Al?Melioco; the old corsar and pirate on opposite; and Al?Salettino (Ali from city of Sal?; representing an adult prisoner with lots of physical power and energy. The name of the African is unknown.
