The 1st-century Roman cookbook Apicius makes various mentions of recipes which involve a pie case.[5] By 160 BC, Roman statesman Marcus Porcius Cato (234-149 BC) who wrote De Agri Cultura, notes the recipe for the most popular pie/cake called Placenta. Also called libum by the Romans, it was more like a modern-day cheesecake on a pastry base, often used as an offering to the gods. With the development of the Roman Empire and its efficient road transport, pie cooking spread throughout Europe.[2]
