Painted in 1646 on a panel less than nine inches wide, Rembrandt’s Abraham Entertaining the Angels is a work of intense spirituality. Privately owned, it had a rare public showing at The Frick Collection in New York in 2017. This associated study places the painting as the first of a series of ten depictions of divine intervention in human life. A further 26 illustrations relate it to work by Rembrandt’s predecessors and contemporaries.
