There are many gaps and uncertainties in the magic lantern's recorded history. A separate early magic lantern tradition seems to have been developed in southern Germany and includes lanterns with horizontal cylindrical bodies, while Walgensten's lantern and probably Huygens' both had vertical bodies. This tradition dates at least to 1671, with the arrival of instrument maker Johann Franz Griendel in the city of [[Nuremberg|Nürnberg]], which Johann Zahn identified as one of the centers of magic lantern production in 1686. Griendel was indicated as the inventor of the magic lantern by Johann Christoph Kohlhans in a 1677 publication.<ref name=Rossell2009 /> It has been suggested that this tradition is older and that instrument maker Johann Wiesel (1583–1662) from [[Augsburg]] may have been making magic lanterns earlier on and possibly inspired Griendel and even Huygens. Huygens is known to have studied samples of Wiesel's lens-making and instruments since 1653. Wiesel did make a ship's lantern around 1640 that has much in common with the magic lantern design that Griendel would later apply: a horizontal cylindrical body with a rosette chimney on top, a concave mirror behind a fixture for a candle or lamp inside and a biconvex lens at the front. There is no evidence that Wiesel actually ever made a magic lantern, but in 1674, his successor offered a variety of magic lanterns from the same workshop. This successor is thought to have only continued producing Wiesel's designs after his death in 1662, without adding anything new.<ref>{{cite book|url=https://www.academia.edu/20378426|title=The Origins of the Magic Lantern in Germany|last=Rossell|first=Deac|year=2004}}</ref>
