Johannes Frobenius (c 1460-1527), was educated at Basel. In 1491 he set up a printing business there. He used this image of caduceus held by two hands emerging from clouds on the title pages of his books. Although this is is merely a mark to indicated that the book emanated from the printing house of Frobenius, it could be mistaken as a hermetic or even an alchemical emblem. |
Another more sophisticated emblematic printer's device from 1565. Here it is a woodcut used by Sigmund Feyerabend a printer at Frankfurt. Feyerbend used a number of different printer's marks or devices. This could be easily confused with an actual emblem. |
Printer's mark of Berthold Rembolt Paris 1512, based on the tree of life with two lions and a sun. Again easily confused with an alchemical emblem. |
