Beware of Dog! This common warning sign has probably been around as long as the dog has been domesticated and hu- mankind has known how to write. An archaeological dig in Ita- ly found such a sign (Cave canem!) on a house among ancient Roman ruins, and Petronius Arbiter (d. a.d. 66) records the warning in his Satyricon. See one good turn. |
