One idea could be to consider purchasing him a series of lectures from The Great Courses Plus. They have a range of courses on cultural history topics taught by highly regarded experts in the field. Alternatively, you could also consider a book on a cultural history topic that he may be interested in, such as "Sapiens: A Brief History of Humankind" by Yuval Noah Harari or "Guns, Germs, and Steel" by Jared Diamond. For an added personal touch, you could also include a gift card to his favorite coffee shop or bookstore to enjoy while he dives into his new gift.
Or you can get him a star map with the date when he was born.
