Focus on San Zeno Altarpiece (Mantegna) and explore the Provenance.
The San Zeno Altarpiece was originally created for the Basilica of San Zeno in the town of Verona in northern Italy and currently still stands there. As described above (see: predella), Napoleon stripped the panel apart, taking the central panel, as well as the three predella paintings to Paris in 1797. Only the central panel was returned after Napoleon lost power in 1815, but the three original predella have never been returned, and thus those seen in the altarpiece today are copies.
