Saint Mary Magdalene, with an Angel [left panel]

Attributed to Pietro Lorenzetti and dated to 1340, this panel likely entered the art market in Florence by 1924, though contemporary reports were imprecise regarding its attribution. By 1926, the work was in the collection of Alessandro Contini in Rome, who gathered expert opinions on the triptych that year. Correspondence involving Contini, restorers, and advisor Paul Sachs indicates that Felix M. Warburg of New York purchased the panel in 1927.

Following Warburg's death, ownership passed by inheritance to his wife, Frieda Schiff Warburg. In 1941, she gifted the painting to the National Gallery of Art in Washington, D.C., where it remains part of the permanent collection.

Scholarship situates the left panel of the Saint Mary Magdalene triptych within Pietro Lorenzetti's early 14th-century output, noting its religious subject and tempera technique. Early twentieth-century dealers and collectors, including Alessandro Contini and Felix Warburg, documented its provenance, while art historians such as Raimond van Marle and Miklós Boskovits referenced it in discussions of the Lorenzetti bottega. The work's inclusion in the National Gallery of Art's collection has reinforced its reputation as a key example of Sienese Gothic painting, illustrating the artist's role in bridging Byzantine tradition and naturalistic detail.

Pietro Lorenzetti, an Italian painter active in the first half of the 14th century, created Saint Mary Magdalene, with an Angel around 1340. This work, originally tempera on panel and later transferred to canvas, exemplifies the Sienese artistic tradition of its era. It depicts a religious narrative, showcasing the artist's engagement with naturalistic representation within a devotional context.
