"Nature forging a baby"
Forget conception or little homunculi, just make your babies in a forge.
But when Nature, sweet and compassionate, sees that envious Death and Corruption come together to put to destruction whatever they find within her forge, she continues always to hammer and forge and always to renew the individuals by means of new generation.
[Guillame de Lorris and Jean de Meun, Roman de la Rose. From Bruges c.1490-1500.]
