Blazon: Per pale azure six molets of as many points in pile argent within a bordure indented throughout of the first and the second and per quarterly or and azure, four lozenges counterchanged
The arms on the dexter half of the shield are those of the Altieri family. This may be due to the fact that Felice Rospigliosi, the brother of Pope Clement IX, was elevated to cardinal by Pope Clement X (born Emilio Altieri) in 1673.
In use since 1200s?
Blazon: Per quarterly or and azure, four lozenges counterchanged
The Rospigliosi family originated from Milan, but moved to Pistoia in the late 12th century. In the later 1300s, the Rospigliosis became known for their involvement in the wool and cloth trades, as well as tax collection and spices. Their prestige only increased after Giulio Rospigliosi became Pope Clement IX in 1667.
In use since at least 1324; variations dating back to 1055
Blazon: Argent on a cross azure five crescents or
Some sources place the origin of the family and the arms around 508 BCE, or even earlier during Roman times, but this is probably a fifteenth-century embellishment added after Enea Silvio Bartolomeo Piccolomini became Pope Pius II. From the Middle Ages through 1821, Piccolomini marriages were tightly controlled by a consortium to ensure that their considerable wealth and property stayed within the family. Two branches of the Piccolomini survive today – the Piccolomini Naldi Bandini and the Piccolomini Clementini Adami.
In use since 1413? (possibly earlier)
Blazon: Bendy dancetty or and azure, on a chief of the first an eagle displayed sable
The Petruccis ruled Siena from 1487 until 1529. The name is allegedly derived from the small stature of the founder of the house, Pietro d’Altomonte, who was called by the diminutive Petruccio. The eagle in the arms may be derived from the Marescotti coat of arms, as Pietro married Giulia Marescotti.
In use since 1444?
Blazon: Bendy of six azure and or, on a chief of the last a double-headed eagle displayed sable, armed and crowned of the second
Around 1140, the family came into possession of a castle on the hill Mons Feretrius (Hill of Jupiter Feretrius), from which the family name is derived. It seems likely that they began using the eagle in their arms (sometimes on a chief, as seen here, and sometimes on one of the bends) when they were appointed Dukes of Urbino in 1444.
Blazon: Per quarterly I and IV o five torteaux in orle, in chief a roundel of France (Medici), II and III gules a fess argent (Austria)
These are Marie’s arms from before her marriage. In a classic example of quartering, the first and fourth quarters display the arms of her father, Francesco I de’Medici, Grand Duke of Tuscany, while the second and third come from her mother, Archduchess Joanna of Austria. Since both parents were armigers, all of their children would have been entitled to bear their arms quartered. Upon marrying King Henry IV of France, she would have quartered his arms in the first and fourth quarters with the above arms in the second and third.
In use 1465 – 1737
Blazon: Or five torteaux in orle, in chief a roundel of France
In 1465, King Louis XI of France granted Piero di Cosimo de’Medici (also known as Piero the Gouty) the right to bear a roundel of France as part of the family arms. The grant was apparently made out of respect for the family’s financial acumen rather than as a sign of political or familial affiliation. The Medici continued to bear these arms until they went extinct in 1737, when Gian Gastone de’Medici, Grand Duke of Tuscany, died without issue.
