Baptism of Christ

The gilded terracotta sculpture portrays Saint John administering the baptism of Christ along the banks of the Jordan River. Both figures are positioned atop rock formations that symbolize the riverbanks; Christ inclines slightly forward, presenting his head to the Precursor, who extends his arm to pour the baptismal water, thereby creating compositional balance. A winged angel is situated between them, depicted as gathering a portion of the drapery cascading from Christ’s left arm.
This terracotta model mirrors, in its composition, a silver group crafted by Alessandro Algardi circa 1646. The original silver work was presented to Pope Innocent X, as documented by Giovanni Pietro Bellori (1672, ed. 1976, 409–410): “two small silver statues about three palms high, Saint John the Baptist baptizing Christ, which were donated to the Pope, who was very pleased with them because they alluded to his own name and because he was the patron saint of his family.” 
Although the goldsmith’s piece is now believed to be lost or otherwise dispersed, its provenance can be partially reconstructed. It was initially recorded among the possessions of Prince Camillo at his death in 1666, and later (circa 1684) appears in the inventory of his son Giovanni Battista (1648–1709; see Montagu 1985, II, 310–311, no. L.8).
The critical history of the work housed in the Museo di Palazzo Venezia is closely linked with other prominent terracotta models. In 1923, an example arrived—alongside a collection of Bernini terracottas—at the Museo Cristiano della Biblioteca Apostolica Vaticana (inv. n. 2426). Initially, Albert Erich Brinckmann (1923–1925, II, 1924, 90–91) attributed the piece to Antonio Raggi, a position subsequently revised when Leandro Ozzola (1926–27, 131–135) advanced the attribution to Melchiorre Cafà. The model’s correct identification as the Baptism of Christ by Algardi was established by Olga Raggio (1971, 16–17). Subsequently, Jennifer Montagu (1985, II, 311, n. 8.B.2) recognized this version as corresponding to the one documented in Cardinal Flavio Chigi’s inventory (c. 1666) at the Casino delle Quattro Fontane. Montagu (1972, 64–78) presented a compelling case supporting Algardi’s authorship of the work in question, specifically citing a bronze version of The Baptism held by the Cleveland Museum of Art (inv. 1965.471). Meanwhile, Jacob Hess (1934, 211, note 1) had previously documented a second terracotta model noted by Marcello Oretti in the Segni family collection in Bologna. This piece was acquired directly from the sculptor: “a baptism of Our Lord in clay, a model made by Algardi, who left it as a bequest to Monsignor Cristoforo Segni Bolognese, who made him his executor on June 9, 1654,” as referenced in Montagu 1985, II, 311, n. 8.L.B.1. This group, previously considered lost and mistakenly identified by Raggio (1971, 34, note 83) as the aforementioned sculpture in the Chigi collection, was subsequently recognized by Montagu (1985, II, 311, n. 8.L.B.1) as the prototype from which both the silver version commissioned for Innocent X and later bronze versions originated. 
The terracotta, long thought to be missing and originally bequeathed by Algardi to Cristoforo Segni—Innocent X's butler and a patron of the Bologna sculptor—was conclusively identified as the example now housed in the Museo di Palazzo Venezia. This identification followed its acquisition by the Italian state in 2004 (G. Pittiglio, in Palazzo Venezia 2009, 36, n. 28). The Segni provenance of the clay group is further substantiated by Cristiano Giometti (2011, 42, n. 15), who bases this attribution on the presence of the winged cherub. This feature is absent from the terracotta piece housed in the Museo Cristiano della Biblioteca Apostolica Vaticana but appears both in the silver version linked to Innocent X—as described in inventory records (cf. Montagu 1985, II, 310–311, n. L.8)—and in higher quality casts, notably those in the Cleveland Museum of Art (inv. 1965.471) and The Nelson-Atkins Museum of Art in Kansas City (inv. 47–34). Additionally, radiodiagnostic analyses (Falcucci, Pelosi 2011, 195–196) have verified the existence of an oxidized silver metal foil beneath the more recent gilding layer. Given this evidence, it is plausible, as Giometti (2011, 41, n.15) suggests, that the Baptism in question was originally intended to emulate the medium of its silver counterpart. This supports its identification as the example gifted by Algardi to the pope’s butler and protector.
The dating of this work, estimated to be around 1646 based on Bellori's account (1672, ed. 1976, 409–410), is further substantiated by Montagu (1972, 64–78; 1985, II, 310–311, n. L.8) through stylistic analysis. Such examination facilitates a comparison between the Baptism and the marble group depicting the Beheading of Saint Paul (Bologna, Church of San Paolo Maggiore), both executed in the 1640s. Additionally, Montagu draws parallels between the present invention and a drawing by Algardi held at the Uffizi (Gabinetto dei Disegni e delle Stampe, inv. 17203F), previously attributed to Algardi by Walter Witzthum (1963, 75–98; 87–89, 90, fig. 29). It is noteworthy that, particularly regarding composition, Christ’s pose in Algardi’s terracotta aligns—in terms of limb positioning and the drape of fabric from the left elbow—with the analogous figure in Annibale Carracci’s Baptism (c. 1603), presently housed in the Kunsthaus, Zurich (inv. 2004/0010).
A recent conference led by Lucia Simonato (Pensieri di terracotta, scritture di bronzo. Algardi e il Battesimo di Cristo, held at Rome's Palazzo Venezia, Sala del Refettorio, on October 11, 2022) focused on the terracotta works housed in the Museo di Palazzo Venezia. Simonato examined these pieces within the broader context of Algardi’s sculptural practice. Due to cultural influences stemming from his Emilian background, Algardi frequently conceived terracottas as independent artworks—originally intended either as gifts for friends and patrons or for clients of more modest means. Notably, this approach is also evident in the Portrait of Innocent X held at the same museum (cf. inv. 13466).

Good. The gilding, though not original, has been consistently well-preserved. 

2011: Diagnostic investigations were performed by Claudio Falcucci and Claudia Pelosi. Technical examinations identified several fractures in the terracotta, which were not readily visible due to coverage by the gilding layer. Radiographic analysis further indicated that the angel, which had been either separated from the group or detached at a later stage, was reattached to the body of Christ with a metal pin passing through the right leg of the winged figure. X-ray fluorescence revealed a difference in the composition of the terracotta mixture between the angel and the other figures; additionally, this analysis detected a silver metal foil beneath the plaster and gilding layers.
