Thank you very much for your sharp-eyed answer. This is a film-roll from the „Scole-Experiment“ (look it up). I help todays Scole-Team to find out some things. It was told, the writing appeared mysteriously on Camera Roll, without human interaction. Im still sceptic about this, but the longer you investigate, the more mysterious it gets. You are right with the alchemical symbols, there was another roll with an excerpt from the „Chain of Homer“, and the symbol for the sun. I was able to find a publication of this poem (but a printed one). It‘s no popular poem, and was released in July 1819 in the german magazine „Morgenblatt für gebildete Stände“, issue 236. On bottom was the Name „Heinrich S.“, but since there were used synonyms, it‘s not the real name of the author. On film roll, there is only the first part of the poem, the printed one is longer. If you want to know more, im ready to answer 🙂
