Costabili Palace and the Architecture “All’Antica” in Ferrara at the End of the XV Century

Costabili Palace, also known as Ludovico “il Moro” (Ludovico Sforza, Duke of Milan) Palace, is located in Ferrara on the ancient Ghiara road, occupying the corner that it forms with via Porta d'Amore, in the south-eastern area of the city. Attributed to the architect Biagio Rossetti (1447-1516) it represents, by size and formal wealth, begun but never completed, the most ambitious palace of the Renaissance in Ferrara. Commissioned by Count Antonio Costabili (1450-1527) at the end of the Fifteenth century, the construction was interrupted in 1503. Of four sides of its court only two were built in their rich and cultured architectural language, and only half of the main façade was sketched. Through the unpublished archival research carried out, crossed with the direct study of the building by surveying the relevant stylistic elements, helped by a proportional analysis and the reading of the stratigraphic masonry units, this doctoral research retraces the history of the construction. This work has clarified the role of the artists involved and their relationship with the strong personality of the client Antonio Costabili, ambassador in Milan of the Duke of Ferrara (Ercole I d’Este) from the year 1496 until the year 1499, one of the most representative intellectuals of his time thanks to a solid humanistic and artistic education. From a systematic study of an unfinished building site the precise design of the Costabili Palace will emerge as expression of a clear linguistic and lexical intention, called “all’antica”, inspired to the Roman classical architecture. The proposed research is wondering about the real contribution that the architectural culture in Ferrara at the end of the Fifteenth century, highly represented by the Costabili Palace, offers to the broader context of the Renaissance courts.
