Portrait of Joseph Leeson, later 1st Earl of Milltown (1711-1783)

Joseph Leeson was an Irish gentleman of substantial means who made his Grand Tour in the early 1740s, and this 1744 portrait by Batoni — one of the painter's earlier major portrait commissions — marks a pivotal moment in both men's careers. Leeson would become the first Earl of Milltown and a significant art collector, amassing a collection that eventually formed the core of the National Gallery of Ireland. Batoni in 1744 had not yet achieved the celebrity that would come to define his studio, and portraits like this helped establish his reputation among wealthy foreign visitors. The painting's presence in the National Gallery of Ireland reflects the direct line of descent from Leeson's own collection: these works stayed in family hands for generations before passing to the national institution, making this one of the best-documented provenances among Batoni's Grand Tour portraits. It captures a relationship between artist and collector that would have long consequences for Irish cultural history.

Compared to Batoni's later portraits, this 1744 example shows a slightly warmer palette and a more robust approach to impasto in the light areas. The landscape background, unusual for Batoni, suggests an openness to different compositional solutions before his Roman-interior formula became fixed.
