Question: What was the primary subject of both the March on Washington for Jobs and Freedom and I Have a Dream?
Context: John Henry Olsen, AO, OBE (born 21 January 1928) is an Australian artist and winner of the 2005 Archibald Prize.  Olsen's primary subject of work is landscape. The April (titled Martin Luther King and the March on Washington in the United Kingdom) is a BAFTA-nominated documentary directed by John Akomfrah and narrated by Denzel Washington.  It is about the historic 1963 March on Washington for Jobs and Freedom - largely remembered for Martin Luther King's famous and iconic "I Have a Dream" speech delivered on the steps of the Lincoln Memorial in Washington, D.C. It formed the centrepiece of a special week of programs and online events and activities celebrating the 50th anniversary of the March. In painting, staffage (] ) is the name foe the human and animal figures depicted in a scene, especially a landscape, that are not the primary subject matter of the work.  Before the adoption of the word into the visual arts in the late eighteenth and early nineteenth centuries, "Staffage" in German could mean "accessories" or "decoration".  The word can be used in two senses: as a general term for any figures in a work, even when they are, at least ostensibly, the main subject, and as a descriptive term for figures to whom no specific identity or story is attached, included merely for compositional or decorative reasons.  In the latter sense, staffage are accessories to the scene, yet add life to the work; they provide depth to the painting and reinforce the main subject, as well as giving a clear scale to the rest of the composition. The vanishing Sun model is a thought experiment in physics which imagines the physical consequences to the light and gravity if the Sun were to disappear.  In these models, the Earth is the primary subject, and the light and the Sun's gravitational attraction are the primary focus. The nude figure is a tradition in Western art, and has been used to express ideals of male and female beauty and other human qualities.  It was a central preoccupation of Ancient Greek art, and after a semi-dormant period in the Middle Ages returned to a central position in Western art with the Renaissance.  Athletes, dancers, and warriors are depicted to express human energy and life, and nudes in various poses may express basic or complex emotions such as pathos.  In one sense, a nude is a work of fine art that has as its primary subject the unclothed human body, forming a subject genre of art, in the same way as landscapes and still life.  Unclothed figures often also play a part in other types of art, such as history painting, including allegorical and religious art, portraiture, or the decorative arts. Evon Streetman (b. 1932) is an American photographer.  Streetman's primary subject is Florida, where she lives. The March on Washington for Jobs and Freedom, the March on Washington, or The Great March on Washington, was held in Washington, D.C. on Wednesday, August 28, 1963.  The purpose of the march was to advocate for civil and economic rights for African Americans.  At the march, Martin Luther King Jr., standing in front of the Lincoln Memorial, delivered his historic "I Have a Dream" speech in which he called for an end to racism. Medieval Exegesis: The Four Senses of Scripture, is a three volume study by Henri de Lubac, first published in French between 1959 and 1964.  It is considered to be one of the most important and thorough studies of the history of medieval exegesis.  Its subject matter ranges from the early Christian Patristics to the later Middle Ages and its primary subject matter, as its subtitle suggests, is the development of the four-fold method of scriptural interpretation, i.e., allegory, typology, tropology, and anagogy. "I Have a Dream" is a public speech delivered by American civil rights activist Martin Luther King Jr. during the March on Washington for Jobs and Freedom on August 28, 1963, in which he calls for an end to racism in the United States and called for civil and economic rights.  Delivered to over 250,000 civil rights supporters from the steps of the Lincoln Memorial in Washington, D.C., the speech was a defining moment of the Civil Rights Movement.
