One idea could be to give your granddaughter a framed art print of a famous Renaissance painting, like "The Birth of Venus" by Botticelli or "The Mona Lisa" by Da Vinci.
Another idea could be to get her a book about the Renaissance, like "The Renaissance: A Very Short Introduction" by Jerry Brotton or "The Civilization of the Renaissance in Italy" by Jacob Burckhardt.
You could also consider buying her a set of Renaissance-inspired calligraphy pens and ink or a beautifully designed journal where she can practice her writing in the style of Renaissance scribes.
Finally, if she enjoys board games, you could get her a game like "Lorenzo Il Magnifico" or "The Castles of Burgundy," both of which are strategy games set during the Renaissance period.
Or you can get her a star map with an important date you share.
