This Renaissance-era cutlery dates back to the 16th century. These extremely rare knives are engraved with musical scores complete with lyrics. On one side is a benediction that may have been sung before a meal, and then a grace on the reverse side that was sung after eating. What isn’t clear to historians is how this may have all played out in actuality. It would be uncommon for a wealthy Italian family who might have possessed such opulent knives to cut their own meat, the task instead performed by a squire. But perhaps they were reserved only for special ceremonies or holidays.
