Raffaello da Montelupo (c. 1504/1505 – c. 1566/1567), born Raffaele Sinibaldi, was a sculptor and architect of the Italian Renaissance, and an apprentice of Michelangelo. He was the son of another Italian sculptor, Baccio da Montelupo. Both father and son are profiled in Vasari's Le Vite delle più eccellenti pittori, scultori, ed architettori (or, in English, Lives of the Most Excellent Painters, Sculptors, and Architects). Works Raffaello was born in Montelupo Fiorentino, near Florence. As a young artist in his twenties, he assisted Lorenzetto in Rome with the execution of statues of Elijah and Jonah for the Chigi Chapel in Santa Maria del Popolo (on designs by Raphael). He is also attributed a marble relief of the mystical marriage of St. Catherine (c. 1530), in a chapel at Santa Maria della Consolazione. Raffaello then went to Loreto, where the Visitazione and Adorazione dei Magi (c. 1534) at the Basilica of the Holy House (Chiesa della Casa Santa) are attributed to him (on designs by Andrea Sansovino). Shortly thereafter, according to Vasari, Raffaello began work in Florence with Michelangelo, at the Medici Chapel (Sagrestia Nuova) of the Basilica di San Lorenzo, where he created San Damiano (c. 1534). St. Cosmas is also attributed to him, together with Giovanni Angelo Montorsoli, another assistant to Michelangelo. He returned to Rome, continuing to work as a sculptor under the direction of Michelangelo. There he contributed to work on the tomb of Julius II at San Pietro in Vincoli, and contributed (along with Bandinelli) to the tomb of Pope Leo X at Santa Maria sopra Minerva. For the chapel constructed by Leo X at the fortress of Castel Sant'Angelo, Raffaello created a Madonna. In addition, he sculpted a marble statue of Saint Michael holding his sword, designed to stand atop the Castel. (Legend holds that in 590 the Archangel appeared atop what was then the mausoleum of Hadrian, sheathing his sword as a sign of the end of the Roman plague, thus lending the fortress its present name). Raffaello's St. Michael was later replaced by a bronze statue of the same subject, executed by Flemish sculptor Peter Anton von Verschaffelt in 1753. His version may still be seen in an open court in the interior of the fortress. Under Pope Paul III, Raffaello was commissioned to create fourteen angels to adorn Ponte Sant'Angelo, the bridge connecting Rome's center to the Castel Sant'Angelo. Those sculptures were
