This is the official coat of arms of the Aloigi Luzzi family, which is included in the Register of Nobles of the city of  Sansepolcro. The register is also called ‘The Golden Book”. It can be consulted even today in the Historical Archive of Sansepolcro Township.
The coat of arms on the opening page of the web site was painted on a dish for the wedding of Costanza Gherardi and Pietro Aloigi, celebrated in 1718.
