Do artigo da Wikipedia sobre História do bolo ,
During the Roman period, the name for cake became “placenta” which was derived from the Greek term. Placenta were baked on a pastry base or inside a pastry case.
The Greeks invented beer as a leavener, frying fritters in olive oil, and cheesecakes using goat's milk. In ancient Rome, basic bread dough was sometimes enriched with butter, eggs, and honey, which produced a sweet and cake-like baked good. **Latin poet Ovid refers his and his brother's birthday party and cake in his first book of exile, Tristia.

11 What hast thou to do with Pontus ? Is it that Caesar's wrath
sent thee too to the remotest land of the world of cold ?
Thou awaitest, I suppose, thine honour in its wonted guise :
a white robe hanging from my shoulders,
a smoking altar garlanded with chaplets,
the grains of incense snapping in the holy fire,
and myself offering the cakes that mark my birthday
and framing kindly petitions with piousTRISTIA III, XIII. A BIRTHDAY AT TOMIS
