Postcard - ‘ourobouros’.
The work of the potter is to mix dry earth and water and form his vessels. The alchemist can learn from him: a proper mixing ratio of the elements is important. 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.
