San Sebastiano (Mantua)

San Sebastiano (Mantua)

San Sebastiano is an Early Renaissance church in Mantua, northern Italy.

Begun in 1460 according to the designs of Leon Battista Alberti, it was left partially completed in the mid 1470s, by which time construction had slowed and was no longer being directed by Alberti. As a consequence, little remains of Alberti’s work apart from the plan, which is considered one of the earliest and most significant examples of Renaissance centrally-planned churches. The plan is in the shape of a Greek cross, with three identical arms centring apses, under a central cross-vaulted space without any interior partitions. The church sits on a ground-level crypt which was intended to serve as a mausoleum for the Gonzaga family. [Franco Borsi. "Leon Battista Alberti" (New York: Harper & Row, 1977)]

The complete absence of columns in the façade signified for Rudolf Wittkower [Rudolf Wittkower, "Architectural Principles in the Age of Humanism", (1962) 1965: pp 47-53, p 47] a decisive turning-point in Alberti's interpretation of architecture, moving beyond his statements in "De Re Aedificatoria" where he considered the column the most noble ornament of building. The façade concealing a narthex that runs the full width of the structure is precisely as wide as its height from the entrance level to the apex of the pediment; it may be fitted with the perfect geometry of the square. The temple front has been converted by Alberti into wall-architecture, as Wittkower noted, and a complete series of pilasters, like pillars embedded in the wall, has been elided to the two outermost, and the two flanking Pellegrino Ardizoni's clumsy doorway, ["Ardizoni finished the church to the best of his poor ability... Careless and without imagination, he here copied exactly the frame of the central door which leads from the vestibule into the church" (Wittkower, 1965:50f).] which overlaps them and ill suits its space. A surviving letter of 1470 from the patron, Ludovico II Gonzaga, Marquis of Mantua, to the on-site architect agreeing with Alberti's proposal to reduce the number of pilasters on the portico [Wittkower's reconstruction of Alberti's original intentions (Wittkower 1965 p 52 fig. 7) features the order of six pilasters dividing the façade into the five bays still represented by the doors.] illuminates Alberti's plan of 1460.

The two outer staircases were added in the twentieth century; prior to 1925 old photographs show the entrance was a single stair to the quattrocento loggia appended to Alberti's design. Wittkower demonstrates that Alberti's plan comprised a set of stairs the full width of the façade leading to five doors (three of which have been filled in as dysfunctional balconies).

The most unexpected motif in the façade is the central break in the entablature presented by the window opening, doubtless intended to be arch-headed under the arched entablature that joins the outer sections, a motif that Wittkower conjectured Alberti knew from the side elevations of the Roman triumphal arch at Orange.
