No paintings were attributed to Lochner until J.F. Böhmer named him as the painter of the Altar of the City Patrons in an article published in 1823. He based his attribution on a mention of a visit to Cologne in 1520 in the diary of Albrecht Dürer, in which the artist notes paying to see an altarpiece by "Maister Steffan". Böhmer identified this as the Altar of the City Patrons, and "Maister Steffan" as the documented Stefan Lochner.Which you can believe or not as suits your temperment. But whether Böhmer's identification is correct, others have identified several other works as being by the artist who painted the Cologne altarpiece. Above is the most famous of the works attributed to "Lochner," the Rose Garden Madonna or Madonna in the Rose Bower. This is one of my favorite Madonnas, and even the baby Jesus isn't bad.
