The @ sign is used in an electronic mail address to separate
the local part from the hostname.
It is ironic that @ has become a trendy mark of Internet
awareness since it is a very old symbol, derived from the
latin preposition "ad" (at).
Giorgio Stabile, a professor of history in Rome, has traced
the symbol back to the Italian Renaissance in a Roman
mercantile document signed by Francesco Lapi on 1536-05-04.
In Dutch it is called "apestaartje" (little ape-tail), in
German "affenschwanz" (ape tail). The French name is
"arobase". In Spain and Portugal it denotes a weight of about
25 pounds, the weight and the symbol are called "arroba".
Italians call it "chiocciola" (snail).
