How about a personalized portrait drawn in the style of a Renaissance painting? You could commission an artist who specializes in that style of art to create a portrait of your friend, incorporating elements that reflect their interests or personality.
Another idea could be a book or collection of literature set during the Renaissance period, perhaps including works of Shakespeare or Dante. You could also consider a package of Renaissance-era inspired items such as a wax seal for letters, quill pen, and ink set.
Finally, you could explore the option of gifting tickets for a Renaissance fair. They offer amazing interactive experiences and showcase performances and activities based on that period.
Or you can get her/him a star map with an important date you share.
