There is one small detail which might be completely innocent, or it might be a hint at something of interest to Øystein? At one point in Apologia Poetica, Bessler makes reference to his blue-apron’d assistant, which we know referred to Gottfried. I did some research into the use of the term during Bessler’s era and there are references to Free Masons and their use of aprons and in particular, blue ones. I’m not saying this is conclusive, merely possibly suggestive of a link. It may also refer to apprentices, which of course also links to Free Masons, but also to indentured apprenticeships.
Blue aprons in modern times are closely linked to chefs who wear them while learning to cook, and it is difficult to eliminate that relation from the one we seek which was evident over 300 years ago.
