 The portrait entered the Prussian royal collection with the purchase in 1821 of the Edward Solly collection, from which the then-recently formed Gemäldegalerie, Berlin, was allowed to take its pick.It was positively identified in 1825 as an original by Christus when Waagen identified the lettering on the (now lost) frame "PETR XPI" as shorthand for "Petrus Christophori", which he associated with the "Pietro Christa" mentioned by Giorgio Vasari in the 1568 edition of his "Lives of the Most Excellent Painters, Sculptors, and Architects".In this way, Waagen also identified Christus' so-called "Saint Eligius" panel, now in the Metropolitan Museum of Art, New York (and seen as just a portrait of a goldsmith), marking the painter's rediscovery after centuries of obscurity.
