Thomas John Horsley – Portrait of Thomas Forsyth Watercolour C1820

19th century
Description

Profile portrait of Thomas Forsyth (1796–1858), husband of Margaretta Wright. The watercolour on card is housed in a leather case with convex glass. Two handwritten labels identify the artist as T. J. Horsley and date the work to around 1820. The case is somewhat worn, and the convex glass does not fit especially well, though it remains secure. The portrait itself appears to be in good condition. The photograph showing a single label on the inside of the case was taken with the glass in place; the other two photographs, including the close-up, were taken without the glass.

Image: 3 x 2 7/16 in. (7.7 x 6.2 cm.)

Case: 3 1/2 x 2 7/8 in. (9 x 7.2 cm.)

Thomas John Horsley was a Sunderland-born portrait painter who specialised in watercolour portraits, including miniature works on ivory. Born in Bishopwearmouth on 7 October 1795, he was the son of Thomas Horsley, a noted oil painter who painted John Wesley during the Methodist preacher’s visit to the area. As a young man, Horsley moved first to Hull and then to London, where a small number of his paintings were shown at the Royal Academy between 1820 and 1833. He later returned to Bishopwearmouth, where he continued to paint miniature portraits. Horsley died on 10 July 1870 and was buried three days later in Bishopwearmouth Cemetery. At the time of his death, he lived in Derwent Street; the cause was bronchitis, then commonly known as “the old man’s enemy.”

Antiques are the ultimate green purchase. By choosing historical pieces over newly manufactured goods, you completely eliminate the carbon footprint of modern mass production while preserving exceptional, timeless craftsmanship.

A portrait miniature from the Regency era, produced between 1795 and 1837, is a small-scale, detailed likeness painted in watercolour or gouache on card, vellum, or ivory. These personal artworks were typically commissioned as private tokens of affection and kept in hinged leather cases or lockets.

Artists traditionally applied watercolour pigments mixed with gum arabic onto substrates of thin wafer ivory, vellum, or heavy card. The completed miniatures were mounted inside protective oval brass surrounds and set within leather-bound cases or wooden frames.

Authentic period miniatures display delicate hand-painted stippling and cross-hatching under magnification, rather than mechanical print dots. Period-appropriate clothing, natural age patina on materials, and historical artist inscriptions or sitters labels further confirm authenticity.

Portrait miniatures function as accent pieces when placed on a bookshelf, desktop, or mantelpiece. They can also be integrated into gallery wall arrangements, adding historical depth and visual texture to quiet corners or alcoves.

Watercolour miniatures must be kept out of direct sunlight and high humidity to protect against pigment fading and substrate warping. They should remain in their protective cases or frames under glass and be dusted lightly with a clean, dry microfibre cloth without using liquid cleaners.
