However, Europe was yet to be introduced to Polo, so the suit was transformed unto batons and staves. And together with swords are still traditional suits of Spanish and Italian cards. In the 15th century, German card makers started experimenting with suits that were loosely based on Italian suits and eventually came up acorns, leaves, hearts, and bells. The suits are still in use today.
The French in 1480 simplified the shapes into trefle (clover), pique (pike heads), Coeur (hearts), and carreau (paving tiles). English card makers then used the shapes but changed the names. Spade (pique) might reflect the earlier use of Spanish suit symbols, with Espadas meaning swords. Clubs are what the Spanish suit of staves actually looks like, and Diamond is the paving tile’s shape. It was also during the 1400s that European cards switched from current royalty to historical or classic figures.
