This bust comes from Palazzo Borghese in Campo Marzio, where it formed part of the decorative programme for the Gallery of Mirrors, together with 15 other portraits of the series. Since 1832 it has been displayed in Room 4 of Villa Pinciana.
The work depicts Emperor Trajan. Framed at the top by his characteristic hairstyle, with the bangs forming a low hairline along the forehead, his face has regular features. His closed lips are framed by clearly visible nasolabial folds. The emperor’s bust shows the paludamentum buttoned with a fibula on his left shoulder, above the cuirass decorated with a Medusa head.
Included in decoration of the Gallery of Palazzo Borghese in Campo Marzio between 1674 and 1676 (H. Hibbard, ‘Palazzo Borghese Studies. II, the Galleria’, The Burlington Magazine, 104 (1962), pp. 9-20); Inventario Fidecommissario Borghese 1833, C, p. 49, no. 111. Purchased by Italian state, 1902.
Marcus Ulpius Nerva Trajanus was Roman emperor between 98 and 117. Here he is depicted with his head turned toward his right. His physiognomy shows all the characteristic traits of the known portraiture of him: his hairstyle is defined by parallel locks which define the hairline across his forehead and which are arranged on two levels on the sides of his face. His slightly squinting eyes and thin eyelids, framed by knitted eyebrows, lend his gaze an energetic expression. His regular nose terminates in a rather thick point, with evident nasolabial folds on either side. The corners of his thin mouth point downwards, while his chin protrudes somewhat.
Trajan’s bust shows the paludamentum gathered together in large folds and buttoned with a round fibula on his left shoulder. This is placed over a cuirass decorated with a protome with the Gorgoneion, the severed head of the Medusa, which was believed to bring luck and offer protection.
The work forms part of a series of 16 busts in porphyry from Palazzo Borghese in Campo Marzio: they reproduce the Twelve Caesars narrated by Suetonius, with the addition of Nerva and Trajan and second versions of Vitellius and Titus. They were formerly placed in recesses in the gallery and framed by an arrangement of plaster reliefs depicting key episodes in the life of each and personifications of their respective virtues; this decoration was executed by Cosimo Fancelli between 1674 and 1676 (Hibbard 1962). The busts remained here until roughly 1830 (Nibby, p. 360): two years later, they are documented as forming part of the display of Room 4 of Villa Pinciana (Nibby 1832, p. 96). To the series was now added a second bust of Vespasian, sculpted by Tommaso Fedeli in 1619, which had been in the Gladiator Room.
According to documents from the Borghese Archive, the series was composed, as we have seen, of the ‘Twelve Caesars’, with the addition of Nerva and Trajan as well as second versions of Vitellius and Titus (Vatican Secret Archive, AB, b. 5688, no. 15, published in Hibbard 1962, appendix, doc. I, pp. 19-20). In 1830 Nibby saw the series when it was still in Campo Marzio, describing the works as ‘16 busts with heads in porphyry, representing the 12 Caesars and 4 consuls’. Two years later, when they had been moved to Villa Pinciana and displayed along the wall of Room 4, he listed them as Trajan, Galba, Claudius, Otho, Vespasian (two exemplars) Scipio Africanus, Agrippa, Augustus, Vitellius (two exemplars), Titus, Nero, Cicero, Domitian, Vespasian, Caligula and Tiberius; this catalogue was confirmed by the 1833 Inventario Fidecommissario.
Yet if this description (which includes a second Vespasian, executed by Tommaso Fedeli in 1619 and transferred from the Gladiator Room) corresponds to the current state of the series, we are left with several uncertainties: to begin with, we must ask what happened to the busts of Caesar, Titus and Nerva, which were present in 1674-76 but do not form part of the series today; secondly, we must wonder who the fourth consul referred to by Nibby in 1830 could be, given that currently only three are represented (Agrippa, Cicero and Scipio Africanus); and finally, we must inquire where the busts of the consuls came from. It is therefore possible that the sculptures displayed in the gallery, which were already present in Palazzo Borghese, did not correspond to those envisioned for the iconographic programme of the vault: this discrepancy may have indeed complicated the identification of the portraits. This theory is supported by the common date of execution of the busts, which critics believe were all sculpted in the same period during the 17th century (Faldi 1954, pp. 16-17; Della Pergola, 1974; Moreno, C. Stefani, 2000, p. 129; Del Bufalo 2018, p. 116).
