the conspirators were aided by the illness of Richelieu and his absence
from the king, and at the siege of Narbonne Cinq-Mars almost induced
Louis to agree to banish his minister. Richelieu, however, recovered,
became acquainted with the attempt of Cinq-Mars to obtain assistance
from Spain, and laid the proofs of his treason before the king, who
ordered his arrest. Cinq-Mars was brought to trial, admitted his guilt,
and was condemned to death. He was executed at Lyons on the 12th of
September 1642. It is possible that Cinq-Mars was urged to engage in
this conspiracy by his affection for Louise Marie de Gonzaga
(1612-1667), afterwards queen of Poland, who was a prominent figure at
the court of Louis XIII.; and this tradition forms part of the plot of
Alfred de Vigny's novel _Cinq-Mars_.

the change had commenced already a century earlier, in the works of
Ghiberti and Donatello in sculpture, and of Brunelleschi and Alberti in
architecture.

CINQUE PORTS, the name of an ancient jurisdiction in the south of
England, which is still maintained with considerable modifications and
diminished authority. As the name implies, the ports originally
constituting the body were only five in number--Hastings, Romney, Hythe,
Dover and Sandwich; but to these were afterwards added the "ancient
towns" of Winchelsea and Rye with the same privileges, and a good many
other places, both corporate and non-corporate, which, with the title of
limb or member, held a subordinate position. To Hastings were attached
the corporate members of Pevensey and Seaford, and the non-corporate
members of Bulvarhythe, Petit Iham (Yham or Higham), Hydney, Bekesbourn,
Northeye and Grenche or Grange; to Romney, Lydd, and Old Romney,
Dengemarsh, Orwaldstone, and Bromehill or Promehill; to Dover,
Folkestone and Faversham, and Margate, St John's, Goresend (now
Birchington), Birchington Wood (now Woodchurch), St Peter's, Kingsdown
and Ringwould; to Sandwich, Fordwic
