Sandbanks Antiques has dated this Queen Anne Oil Portrait to the 17th Century.
Attributed to Michael Dahl (1656–1743)
London, circa 1705–1710
Signed with monogram (lower right)
Oil on canvas, ‘Kit-Cat’ format 92 x 73cm (36 x 28 in.)
Executed in the prestigious 'Kit-Cat' format, a size popularized by London’s most exclusive political and literary clubs, the work depicts a gentleman of substantial status.

The sitter is portrayed in a three-quarter-length pose, his gaze directed toward the left with an air of studied composure. He is adorned in the height of period fashion: a voluminous, cascading allonge periwig that frames his face, signifying his membership in the upper echelons of society. He wears a slate-coloured banyan—a loose, elegant coat worn by scholars and men of leisure—draped over a fine, pleated linen cravat. The precision of the artist’s hand is most evident in the depiction of the sitter’s right hand, where a quill pen is held with grace, poised over a sheet of parchment. This deliberate inclusion of writing materials transforms the portrait from a mere likeness into a visual testament to the sitter’s professional authority and intellectual labour.

Crucially, the work is signed with the artist’s monogram in the lower right corner, serving as an explicit autograph of the master’s hand. Michael Dahl, a Swedish-born master who stood as the preeminent rival to Sir Godfrey Kneller, imbues the sitter with a psychological depth and anatomical sensitivity—most notably in the delicate shading of the eyes and the refined modelling of the hands—that distinguishes his work from the more formulaic portraits of his contemporaries.

Scholarly Context: The artist’s career and unique "artistic personality" are validated by J. Douglas Stewart’s seminal 1973 article, "Some Portrait Drawings by Michael Dahl and Sir James Thornhill" (Master Drawings), which established the modern criteria for authenticating Dahl’s work. His legacy was further affirmed in the 2018 exhibition catalogue, The Spirit & Force of Art: Drawing in Britain 1600–1750 (Lowell Libson & Jonny Yarker Ltd.).
