Schwabe Verlags signet was
Johannes Petri's printer's mark.
His printing workshop was
established in Basel in 1488 and
was the origin of today's Schwabe
Verlag. The signet refers back to
the beginnings of the printing press,
and originated in the entourage of
Hans Holbein. It illustrates a verse of
Jeremiah 23:29: 'Is not my word
like fire, says the Lord, and like a
hämmer that breaks a rock in pieces?'
