Because he missed his fiancée, Bella, who was still in Vitebsk—"He thought about her day and night", writes Baal-Teshuva—and was afraid of losing her, Chagall decided to accept an invitation from a noted art dealer in Berlin to exhibit his work, his intention being to continue on to Belarus, marry Bella, and then return with her to Paris. Chagall took 40 canvases and 160 gouaches, watercolors and drawings to be exhibited. The exhibit, held at Herwarth Walden's Sturm Gallery was a huge success, "The German critics positively sang his praises."
