James Byres

James Byres of Tonley FRSE FSA(Scot) FSA (1733 — 1817) was a Scottish architect, antiquary and dealer in Old Master paintings and antiquities.

He was born in Aberdeenshire in 1733.

Byres was a member of a family of Scottish Jacobite sympathisers who settled in Rome in 1758, where he became a cicerone and an art dealer, mainly to Scottish and English gentlemen on the Grand Tour until his return to Scotland in 1790. His house was in Via Paolina.

Byres was a painter and an adept designer, whose Vanvitellian design for a palazzo facade won a prize from the Accademia di San Luca in 1762. In Rome members of his circle were drawn by Angelica Kauffman in a sketchbook she used from 1762 to 1764: the portraits include the English painter Nathaniel Dance, Gavin Hamilton, and the abbé Peter Grant. By 1764 he was so well acquainted with the ancient sites and the cabinets of collectors that he took about a party of colonial Americans, including Samuel Powel of Philadelphia, who unlike his British peers, took assiduous notes. Byres, as well as some others British residents in Rome such as Thomas Jenkins and Colin Morison, worked as an art dealer, working with important European collectors.

William Constable purchased from Byres many of the Italian paintings and marble copies after Roman sculptures at Burton Constable, Yorkshire, and Byres was responsible for introducing the artist Anton Maron, who painted William Constable and his sister in the pose and dress of Cato and Marcia. Among the antiquities that passed through his hands, the most famous may be the Portland Vase, which he sold to Sir William Hamilton in 1770. Among the commissions for which he acted as agent was the Noli me Tangere of Raphael Mengs, 1771, for an altarpiece for All Souls College, 1771.
