Portrait of Diana, Countess of Mountrath (1696-1766), Wife of the 6th Earl

Hudson's technique is evident in the meticulous rendering of textures: the soft folds of the gray dress, white lace details, and the contrast between the dark hair accessories (red flower and pearl headband) and the muted, dark background.

Created in 1746, the portrait has been acquired by the National Gallery of Ireland, where it remains as a notable work by the artist.

The painting reflects the portraiture conventions of its time, capturing the aristocratic status of the sitter through symbols of wealth and elegance, such as the red velvet chair and ornate clothing.

The portrait stands as a representative example of Thomas Hudson's oeuvre, highlighting his ability to capture the essence of his sitters within the artistic and social norms of 18th-century portraiture.
