Italian family of engravers and medallists, of Bavarian origin. They worked mainly in the Roman mint from the mid-17th century to the end of the 18th. The medals they made are notable above all for their documentary value relating to the history of Rome and the city’s monuments. They were technically skilled but somewhat unimaginative portrait artists. Johan Andreas Hamerani (b Adensburg, c. 1600; d Livorno, 1644) arrived in Rome in 1615 during the pontificate of Pope Paul V. Although he worked in the papal mint, he did not execute annual medals. His son Alberto Hamerani (b Rome, 10 Oct 1620; d Rome, 21 June 1677) worked for a short time at the mint of Massa Carrara, then, between 1657 and 1669, in Rome, as assistant first to Gaspare Morone Mola and later to Girolamo Lucenti. From 1667 he engraved papal seals. Noteworthy among his medals was one commemorating the entry into Rome of Queen Christina of Sweden (1655).
