The major order of the altar for Blaubeuren went to the leading workshop in Ulm, either still under the leadership of the workshop manager Hans Schüchlin or already led by Schüchlin's son Bartholomäus Zeitblom, the rising man in Ulmer painter scene. Since the order exceeded the capacity of this workshop, Bernhard Strigel from Memmingen was called in, who carried out some panels on his own responsibility. Ernst Buchner was the first to point out in 1924 that various employees were also working within the Schüchlin workshop. His proposal of "the deviding of the hands" was widely adopted by the research. According to this proposal,, three painters were involved in the Schüchlin Workshop: Bartholomäus Zeitblom, the Master of the funeral of John (possibly identical to Hans Schüchlins son Daniel Schüchlin) and the master of the beheading of John. Anna Moraht-Fromm questioned Buchner's "handshake". In addition to Zeitblom, she proposes to accept only one other designer of whole plates in the Schüchlin workshop, she calls him Master of the Blue Crucifixion.
