A cleric, possibly
Beilby Porteus, Bishop of London,
 by Henry Edridge, A. R. A., circa 1805.

The Right Reverend Beilby Porteus (1731-1809), Bishop of Chester, 1776-1787 and Bishop of London 1787-1809, served as chaplain to King George III for 40 years.  Porteus was the son of a native of the Virginia colony, who returned to England in 1720.   As a bishop, Porteus was a reformer and an early abolitionist, becoming a vocal supporter of William Wilberforce and Hannah More.  Porteus' celebrated library is housed at Fulham Palace. He was painted by Romney and Hoppner (Fulham Palace); Edridge exhibited a portrait of Porteus at the Royal Academy in 1806, now known only from stipple engravings, examples in the National Portrait Gallery, London.
