In our research for “Ingenious Mechanicks,” we translated parts of a codex from 1505 that was written and illustrated by Martin Löffelholz. In it, Löffelholz showed what are likely the first modern workbenches with a tail vise and face vise. During the translation, we also encountered a recipe for what we thought was a love potion. As “Ingenious Mechanicks” is a woodworking book, and I have no need for a love potion (I’m married), translator Görge Jonuschat and I skipped the love potion section. Until now.... For my birthday, Görge set out to translate the section and perhaps concoct the potion. But what he found was the “love potion” wasn’t exactly about making someone fall in love with you.
