Pandora
The humanist Erasmus of Rotterdam translated Hesiod from Greek to Latin, in the 16th century.  The Greek word pithos is used for a large jar, used for example for storing wine. It can also refer to a funerary jar. Pyxis, on the other hand, is a box. Usually, it is said that Erasmus swapped the words when he translated, so Pandora's jar became Pandora's box. The phrase "Pandora's box" has endured ever since.
