The Seven Hills of Rome: Every English schoolboy at the turn of the 20th century could recite the names of Rome's traditional Seven hills (--girls weren't expected to know such things.) So how did they remember? They used a simple mnemonic (memory jogging) device to remember the first letter of each hill, and here it is, so that we English speaking Romans can remember it too:

Can Queen Victoria eat cold apple pie?

The first letters correspond to:

Capitoline, Quirinal, Viminal, Esquiline, Caelian, Aventine, and Palatine,

or:

Capitolino, Quirinale, Viminale, Esquilino, Caelio, Aventino, e Palatino
 
 
 
 
 

Other "unofficial" hills need not be remembered.
