The altar of the Johanneskirche in Crailsheim is an artistic gem from the workshop of the Nuremberg master Michael Wolgemut. In magnificent colors, scenes from the life and passion of John the Baptist and from the passion of Christ are depicted on the altar wings. The shrine features an expressive crucifixion group with five life-sized sculptures. The accompanying volume gathers contributions from renowned authors who have explored style and iconography, the question of patrons, and restorations. An exciting outcome: with a likely dating around 1490, the question arises whether the young Dürer was involved in the Crailsheim Johannes altar.
