Final answer:
Rosetti & Florescu did not unearth any of the listed items in a casket at Snagov Monastery; the question might be based on a fictional or misinterpreted account.
Step-by-step explanation:
Rosetti & Florescu did not find any of the listed items in the casket they unearthed in Snagov Monastery. The question appears to be a trick question or based on a fictional account, as there's no well-documented historical excavation by individuals named Rosetti & Florescu that resulted in such findings at the Snagov Monastery. While Snagov Monastery is famously associated with Vlad the Impaler, also known as Vlad III Dracula, and there has been speculation about his remains being there, actual archaeological finds have not conclusively supported this. Instead, classical findings typically unearth things like treasure, artifacts, historical documents, or remains of significant historical individuals, but any specific find would need to be confirmed by reliable and documented archeological evidence.
