The snake. Among the Romans the snake was the conventional representation of the
genius loci. (See
Genius.) Hence
figures of serpents were often painted against a wall, as the cross is in modern Italy, and
answered the purpose of our sign “Commit no nuisance” (
Pers. i.113). As the emblem of
Aesculapius (q.v.), the snake was the sign that hung before the Roman pharmacies,
answering to our pestle and mortar. It was also the military ensign of a cohort, being then
commonly termed
draco. See
