In Secrets of Pinar's Game, Roger Boase is the first to decipher a card game completed in 1496 for Queen Isabel, Prince Juan, her daughters and her 40 court ladies. This game offers readers access to the cultural memory of a group of educated women, revealing their knowledge of proverbs, poetry and sentimental romance, their understanding of the symbolism of birds and trees, and many facts ignored in official sources. Boase translates all verse into English, reassesses the jousting invenciones in the Cancionero general (1511), reinterprets the poetry of Pinar's sister Florencia, and identifies Acevedo, author of some poems about festivities in Murcia c. 1507. He demonstrates that many of Pinar's ladies reappear as prostitutes in the anonymous Carajicomedia two decades later.
