Sources-Thuring von Ringoltingen

Melusina: Die schöne und liebliche Histori oder wunderbarliche Geschicht (1456) by Thüring von Ringoltingen

This German version was translated into other languages including English. If like me, you can’t read old German it’s still worth looking at the German edition because of the many woodcut illustrations which help to tell the story a bit like an early graphic novel. Here are a few examples (not comprehensive) of where versions of it can be sourced, I have tried to link directly to the relevant web page on the site where possible.

Online Books-Full electronic copies are available for free online here is a Google books example.

Online Book shops-For example Abe Books

Book shops-With this being in German it may be a tricky to source but you could try ordering. Try finding an independent local bookshop in your area
