Felix de la Mothe Le Vayer (1547-1625), in his _Legatus_ (Paris,
1579), says "Legatos tunc primum aut non multum post institutos fuisse
cum Pandora malorum omnium semina in hunc mundum ... demisit."

[17] The term _corps diplomatique_ originated about the middle of the
18th century. "The Chancellor Furst," says Ranke (xxx. 47, note),
"does not use it as yet in his report (1754) but he knows it," and it
would appear that it had just been invented at Vienna. "Corps
diplomatique, nom qu'une dame donna un jour a ce corps nombreux de
ministres etrangers a Vienne."

[19] Thus Charles V. would not allow the representatives of the duke
of Mantua, Ferrara, &c., to style themselves "ambassadors," on the
ground that this title could be borne only by the agents of kings and
of the republic of Venice, and not by those of states whose
sovereignty was impaired by any feudal relation to a superior power.

ambassador, he says, need not be received, and he may be expelled. In
actual practice a diplomatic agent who has made himself objectionable
is withdrawn by his government on the representations of that to
which he is accredited, and it is customary, before an ambassador is
despatched, to find out whether he is a _persona grata_ to the power
to which he is accredited.

DIPLOMATIC, the science of diplomas, founded on the critical study of
the "diplomatic" sources of history: diplomas, charters, acts, treaties,
contracts, judicial records, rolls, chartularies, registers, &c. The
employment of the word "diploma," as a general term to designate an
historical document, is of comparatively recent date. The Roman diploma,
so called because it was formed of two sheets of metal whic
