Bernini's terracottas have been exhibited before, but only once as the exclusive focus of an exhibition, and so the ambitiously comprehensive treatment in New York and Fort Worth (with slight variations between the two places) was singular. The display of 36 fragile terracottas attributed to the sculptor and spanning his mature career, from about 1627 to 1672, makes intelligible as never before the visual traces of Bernini working, thinking, instructing and even administering.Although the terracottas were encountered as if independent objects of inherent aesthetic value, a significance Bernini probably did not invest in them, the objective of the exhibition and, more explicitly, of the accompanying catalogue was to elucidate the practical use of these models as components of an extensive, multi-media workshop practice. The organizers achieved this through a scrupulous assessment of authorship in the catalogue entries that combined art historical and technical/ scientific analysis. Their approach reprises the unprecedented technical investigation undertaken for the 1999 Fogg Art Museum exhibition of its 15 Bernini terracottas, which provided new insights into Bernini's distinctive modelling process and workshop practice. Extending the scope of the technical examination to a corpus of terracottas that the organizers attributed to Bernini, the present project furnishes the most inclusive assessment of the sculptor's engagement with clay. Their analysis of 52 models (some not exhibited) - inevitably a fraction of the estimated hundreds now lost - provides an inventory of Bernini's signature marks (like the evocatively named 'over-the-shoulder finger stroke' and 'neck fingernail pinch') as well as a deeper sense of how he shaped designs, presented ideas to patrons and directed assistants using terracottas of various size and finish. Far from being a paean to the master's hand, this focus on Bernini's touch ultimately sheds much-needed light on the complex, shifting and strategic division of labour in a workshop comprising a virtuoso leader, expert sculptors and anonymous novices, each of whom had a finger in production.The core of the Metropolitan installation featured 39 terracotta models (31 by Bernini; others produced in collaboration or by associates), and 29 drawings in chalk, ink and/or wash (26 by Bernini; others workshop productions). The integration of models and drawings highlighted the dialogical character of Bernini's multi-media process, especially how he exploited the representational and mimetic potential of one medium to complement the particular capacities of another. Bernini employed matte terracotta in his Tritons with Dolphins (cat. 11) to capture texture - rippling filaments covering tritons' tails; heads of downy curls; bristly-mouthed dolphins - and used a pen and wash Design for a Fountain with Tritons and Dolphins (fig. 27) to represent water and suggest light and shadow at play. Although the organizers adopted the post-Bernini distinction between the bozzetto (small, preliminary, sketchily executed ideas), and the modello (larger and more resolved), seeing these clay models together exposed their resistance to classification. The decision to display the terracottas in the round also laid bare Bernini's surprising lack of interest in resolving the backs of his bozzetti (and some modelli). …
