How about a medieval history book, such as "The Time Traveler's Guide to Medieval England" by Ian Mortimer? Or a DVD box set of his favorite medieval-themed movies or TV shows, like "Game of Thrones" or "The Pillars of the Earth"? Another idea is a medieval-style board game, like "Kingdomino: Age of Giants" or "Carcassonne", which he can play with friends and family. Finally, if he is interested in learning more about medieval life, you could get him a voucher for a guided tour of a medieval castle or museum exhibit.
Or you can get him a star map with an important date you share.
