Jacobite glass: An 18th-century English drinking vessel
most often used for toasting Prince Charles Edward
stuart (“bonnie Prince Charlie”). The Jacobites were
supporters of the exiled King James ii, who abdicated
in 1698, and of his descendants James Edward stuart
(the “old Pretender”) and his son Charles Edward stuart
(the “young Pretender”). before the defeat of the young
Pretender in 1746, Jacobite glasses were usually engraved
with the English rose, representing the Crown,
and an optimistic motto such as “Redeat” (latin, “May he
return”). After 1746, glasses at first bore cryptic symbols
and messages, but later, secrecy was abandoned. in recent
years, many Jacobite glasses have been shown to
be fakes. See also Williamite glass.
