(John Sire de), an eminent French statesman of the 13th century, who was seneschal or high... high steward of Champagne, and one of the principal lords in the court of Louis IX. He attended that monarch in all his expeditions; and had so much confidence placed in him, that all matters of justice in the palace were referred to his decision, and the king undertook nothing of consequence without consulting him. He wrote the history of St Lewis in French, which is a very curious and interesting piece; and died about the year 1318. The best edition of this work is that of Du Cange, in folio, with learned remarks.
