Content: Includes notes on the creation of sigils and letters from Thomas Hyde offering information on talismans extracted from manuscripts at Oxford. It is also peppered with ritual magic operations and ritual additions to the making of sigils. This manuscript gives the impression that Ashmole was mining astrological image magic texts for magic that worked, and that practical application and experiment, more than the preservation of prior intellectual traditions, drove his activities (source: Klaassen 2013).
