Around 1808–1810, during his time in Madrid, the Danish Ambassador Edmund Bourke may have purchased the painting of St. Bartholomew the Apostle by El Greco which later appears in the 1821 inventory of the Esterházy collection. The Scottish-born George Augustus Wallis was one of the earliest enthusiasts of El Greco; this is proven by a letter he wrote to William Buchanan in 1808, in which he describes the then-unknown Spanish master. The knee-length figure of St. Bartholomew is closely connected to the so-called Study of a Head in the Museum of Fine Arts, Budapest, which is a fragment of a painting of St. Bartholomew likewise originating from a series of Apostles.
