Also, contemporary historians have traced the provenance of the manuscript back through Rome and Prague to as early as 1612, when it was perhaps passed from Holy Roman Emperor Rudolf II to his physician, Jacobus Sinapius.
Mūsdienu vēsturnieki ir arī izsekojuši manuskripta izcelšanos cauri Romai un Prāgai līdz pat 1612. gadam, kad to, iespējams, Svētās Romas imperators Rūdolfs II nodeva savam ārstam Jākobam Sinapijam.
