Postcard - ‘Brother and Sister should be joined’.
In alchemy their love is necessary as they complete each other. He is hot, dry and choleric; she is cold, moist and phlegmatic. Michael Maier (1568-1622) describes phases from the alchemical process in Atalanta fugiens, 1618.
There is a brief explanation of the image on the reverse of the card.
