His portraits in oil and
pastel enjoyed some vogue, his first reputation was made by his miniature portraits. In middle life his most popular work consisted of heads in
blacklead pencil, for which he charged two guineas; leaders of fashionable society employed him to make these drawing. Later he concentrated his energies on etching in the style of
Rembrandt, using a
dry-needle with triangular point. He copied some of Rembrandt's prints, among them the artist's portrait of himself and the hundred-guelder plate. An etching after Rembrandt's portrait of Sir John Astley was described by
Horace Walpole as Worlidge's ‘best piece.’ Worlidge drew a pencil portrait of himself, which is reproduced in Walpole's
Anecdotes (edition by
Ralph Nicholson Wornum). Examples of Worlidge's drawings and etchings are in the
British Museum print-room. There is also there a priced catalogue of a selection of his etchings. One of Worlidge's most popular plates depicted the installation of
John Fane, 7th Earl of Westmorland as chancellor of the university at the
Sheldonian Theatre at Oxford in 1761. Worlidge represents himself in the gallery on the right in the act of drawing the scene with his second wife beside him. In the corresponding place on the left-hand side of the plate is a portrait of his brother-in-law, Alexander Grimaldi. Most of the numerous heads and figures are portraits. A plate of the bust of
Cicero at Oxford (known as the Pomfret bust) also enjoyed a wide vogue. in character as Tancred from
James Thomson's
Tancred and Sigismunda, 1752. In April 1754 Worlidge had a large collection of his works to be sold by public auction. The printed catalogue bore the title, ‘A Collection of Pictures painted by Mr. Worlidge of Covent Garden, consisting’ ‘of Histories, Heads, Landscapes, and Dead Game, and also some Drawings.’ The highest price fetched was £51 15
s. 6
d., which was given for a ‘fine head’ after Rembrandt. More than sixteen hundred prints and more than thirteen hundred drawings by Worlidge were sold by
Abraham Langford in March 1767 by order of his widow. Worlidge's last work was his
Antique Gems, a series of 182 etchings of gems from the antique (three are in duplicate). The series was published in parts, some of which seem to have been issued as early as 1754; but Worlidge died before the work was completed. It was finished by his pupils
William Grimaldi and
George Powle, and, printed on satin, was published by his widow in 1768 at the price of eighteen guineas a copy. The frontispiece, dated 1754, shows Worlidge drawing the Pomfret bust of Cicero; behind on an easel is a portrait of his second wife, Mary. No letterpress was included originally in the volume, but between 1768 and 1780 a few copies were issued with letterpress. After 1780 a new edition, but bearing the original date of 1768, appeared with letterpress in two volumes at five guineas each. The title-page omits mention of ‘M. Wicksteed's’ name, but is otherwise a replica of the first. Some of the old copper plates (108 in all) were reproduced in ‘Antique Gems, etched by T. Worlidge on Copper Plates, in the Possession of Sheffield Grace, Esq.,’ London, 1823, (privately printed).
Charles William King in his
Antique Gems (1872, i. 469) thought Worlidge's plates often inferior to those of
Jonathan Spilsbury, and that the descriptions placed below contained some blunders. ==Family==
