Google translates the caption as: Jost Amman’s trade mark for Sigmund Feyrabend [Feyerabend] in his company with Weigand Hanund George Rab. One of the earliest and most ingenious Logos of the master. In the original size.
A barefoot angel dances on top of an urn or fountain, blowing twin pipes or trumpets. On either side of the angel, cherubs bear laurel wreaths. Below, an eagle and a cockerel.
I made separate images of the left-hand cherub, facing to the right;
the right-hand cherub, facing to the left;
the rooster or cockerel,
and the trumpeting angel-woman.
The various symbols on this piece presumably have alchemical significance.
I also have Volume I.
