Giovanni Battista Guelfi

Giovanni Battista Guelphi or Guelfi (1690–1736) was an Italian sculptor who worked in England in the early 18th century.

He was born in Italy in the late 17th century.

He trained under sculptor Camillo Rusconi in Rome and in 1714 was invited by Richard Boyle, 3rd Earl of Burlington to move to England, where he restored the Arundel marbles and executed several portrait busts and monuments.

He left England in 1734 and sailed home to Italy where he settled in Bologna, dying there in 1736.
