From Icelandic Fairy Tales, illustrated by E. A. Mason, 1897.

Here's some duplication from 1936.

Watercolor of a hermetic androgyne, after Salomon Trismosin's sixteenth-century alchemical manuscript, Splendor Solis.  The text reads, "The Philosophers take for example an Egg, for in this the four elements are joined together.  The first or the shell is Earth, and the White is Water. but the skin between the shell and the White is Air, and separates the Earth from Water; the Yolk is Fire, and it too is enveloped in a subtle skin, representing our subtle air, which is more warm and subtle, as it is nearer to the Fire, and separates the Fire from the Water.  In the middle of the Yolk there is the fifth element, out of which the young chicken bursts and grows.  Thus we see in an Egg all the elements comvined with matter to form a source of perfect nature, just so as it is necessary in this noble art."

The third figure from the right has two heads that don't see eye to eye.  The postcard was originally scanned by UpNorth Memories.  (For those intrigued by Janus-faced figures, our Oracle of the Two-Fold Gods is finally in print again, and the first 57 pages are viewable here.  [Note that the preview may take a few moments to load.])

From The Wheel and Cycling Trade Review, 1898.
