that same year the MoMA was the first museum to purchase one of his works. From the mid-1940s, Motherwell became the leading spokesman for avant-garde art in America. His circle came to include William Baziotes, David Hare, Barnett Newman, and Mark Rothko, with whom he eventually started the Subjects of the Artist School (1948–1949). In 1949 Motherwell divorced Maria and in 1950 he married Betty Little, with whom he had two daughters. Motherwell was a member of the editorial board of the Surrealist magazine VVV and a contributor to Wolfgang Paalen's journal DYN, which was edited from 1942 to 1944 in six issues. He also edited Paalen's collected essays Form and Sense in 1945 as the first issue of Problems of Contemporary Art. In 1948 Motherwell executed the image which would prove to be the germ of the Elegies to the Spanish Republic, one of his best known series of works. During 1947–48, Motherwell collaborated with the art critic Harold Rosenberg and others to produce Possibilities, an art review. During the latter year Motherwell created an image incorporating Rosenberg's poem "The Bird for Every Bird", meant for inclusion in the review's second issue. The top half was a handwritten, stylized rendering of the poem's final three lines, and the bottom half was a visual element consisting of roughly rendered black ovoid and rectangular forms against a white background. The stark image was meant to "illustrate" the violent imagery of the poem in an abstract, non-literal way; Motherwell therefore preferred the term "illumination". The second issue of Possibilities did not materialize, and Motherwell placed the image in storage. He rediscovered it roughly one year later and decided to rework its basic elements. This led to the Elegies to the Spanish Republic which Motherwell continued to produce for the rest of his life; several years later Motherwell retroactively titled the original image Elegy to the Spanish Republic No. 1, recognizing it as the series' starting point. A representative example is Elegy to the Spanish Republic No. 110 (1971) which employs the same visual motif of rough ovoid and rectangular forms. The series' abstract imagery has been interpreted as representing violence in Hispanic culture, not necessarily related to the Spanish Civil War of its title. For example, Motherwell himself and others have compared the images to the display of a dead bull's genitalia in the Spanish bullfighting ring. In 1948, Motherwell, William Baziotes,
