Pope Julius III in the context of "Paul III"

Pope Marcellus II (Italian: Marcello II; 6 May 1501 – 1 May 1555), born Marcello Cervini degli Spannocchi, was head of the Catholic Church and ruler of the Papal States from 10 April 1555 to his death, 22 days later.

Marcellus succeeded Pope Julius III. Before his accession as pope he had been Cardinal-Priest of Santa Croce in Gerusalemme. He is the most recent pope to choose to retain his birth name as his regnal name upon his accession, and the most recent pope to date with the regnal name "Marcellus".

Giovanni Pierluigi da Palestrina (between 3 February 1525 and 2 February 1526 – 2 February 1594) was an Italian composer of late Renaissance music. The central representative of the Roman School, with Orlande de Lassus and Tomás Luis de Victoria, Palestrina is considered the leading composer of late 16th-century Europe. Palestrina was one of the few Renaissance composers never entirely forgotten, but it was the so-called "Palestrinian style" of counterpoint—especially as codified by Johann Joseph Fux—rather than his individual compositions that exerted the greatest influence.

Born in the town of Palestrina in the Papal States, Palestrina moved to Rome as a child and underwent musical studies there. In 1551, Pope Julius III appointed him maestro di cappella of the Cappella Giulia at St. Peter's Basilica. He left the post four years later, unable to continue as a layman under the papacy of Paul IV, and held similar positions at St. John Lateran and Santa Maria Maggiore in the following decade. Palestrina returned to the Cappella Giulia in 1571 and remained at St Peter's until his death in 1594.

The Villa Giulia is a villa in Rome, Italy. It is named after Pope Julius III, who had it built in 1551–1553 on what was then the edge of the city. Today it is publicly owned, and houses the Museo Nazionale Etrusco, a collection of Etruscan art and artifacts.

Vincenzo Danti (1530 – 26 May 1576) was an Italian Renaissance sculptor from Perugia.

His father was an architect and goldsmith, and Vincenzo developed an interest in drawing and goldsmithing. In 1545 he went to Rome to study sculpture and in 1553 he managed to secure a commission for a bronze statue of Pope Julius III which was placed outside Perugia Cathedral. In 1557 he went to Florence. In 1559 he made a bronze relief depicting Moses and the Brazen Serpent. This was influenced by bronze reliefs by Donatello. It is cast in low relief and is not finished to a very high degree, but is not non finito either.

Fra' Pietro del Monte (1499 − 26 January 1572) was an Italian nobleman who was the 50th Grand Master of the Order of Saint John from 1568 to 1572.

Pietro del Monte was born in Italy in 1499. His original name was Guido Lotti, but took the name San Savino del Monti in 1550. He was a nephew of Pope Julius III. Prior to his arrival in Malta he was a friar in Capua. He also fought in the siege of Rhodes of 1522.
