There is a canvas (98,5 x 222,5cm) in the Wawel Cathedral that is not connected with any existing or historically documented altars inside the church (il. 1-3). Owing to its shape it has so far been considered to have been a predella, which - taking into account its size and proportions - seems rather unlikely. It may have been the top of the middle part of a retable, possibly in an altar dedicated to the two St. Johns. The painting presents the Virgin Mary with the Child seated under a canopy, attended by the two Saints, adored by kneeling angels with censers in their hands. A graphic model of the scene has been found; it is an engraving by Jan Sadeler (1550-1600) based on a design by Hans von Aachen (1552-1615), released in Munich in 1589 (il. 4). In Albertina, in Vienna, a working copy of the graphic made by Hans von Aachen has been preserved (il. 5) as well as a composition sketch by the same artist at the Herzog Anton Ulrich-Museum in Braunschweig. An inscription on the drawing from 1589 reads: POENA ET PROEMIVM; there are also quotations from psalms and a dedication to Phillip Wilhelm (1576-1598), bishop of Regenzburg in 1589, later cardinal (1596), son of a Bavarian ruler Wilhelm V Wittelsbach (1548-1626). The young hierarch got it in the year of his consecration as a bishop. A pendant to it is the plate by Jan Sadeler of 1590, after Peter Candid (1548-1628), which was dedicated to Phillip Wilhelm’s younger brother - Ferdinand (1577-1650), later bishop of Cologne. The engraving also shows St. Mary with the Child in the company of St. Stephen and St. Laurence. Both works coincide with the artistic activity of Jan Sadeler and Hans von Achen in Munich, where they were summoned by Wilhelm V, and represent strictly planned art created for his court. Another painted version of Sadeler’s engraving was found in a Polish private collection. This is a small, good painting on panel, faithfully reproducing physiognomy and inscriptions known from the prototype. The picture in the Wawel Cathedral, probably painted in Cracow between 1600-1630 and based on the Munich model, is one of the examples of assimilating mannerist engravings from southern Germany in the Cracow environment. Their large influx into Little Poland at the end of the 16th and the beginning of the 17th century may be connected with animated contacts of Sigismund I ll’s court with Bavaria and its artistic centres such as Augsburg, the main purveyor of goldsmith’s work for the Polish king’s court.
