This is the same wine which is now named sherry. Falstaff calls it _sherris
sack_, and also _sherris_ only, using in fact both names indiscriminately
(2 _Henry IV._, Act IV. Sc. 3.). For various commentaries regarding it, see
Blount's _Glossographia_; Dr. Venner's _Via recta ad Vitam longam_,
published in 1637; Nares' _Glossary_, &c. Cotgrave, in his _Dictionary_,
makes sack to be derived from _vin sec_, French; and it is called _seck_ in
an article by Bishop Percy, from an old account-book at Worcester, anno
Elizbethæ 34.
