Background: Jan van Eyck (Dutch: ['jan van 'eik]) (before c. 1390 - 9 July 1441) was an Early Netherlandish painter active in Bruges. He is often considered one of the founders of Early Netherlandish painting, and, one of the most significant representatives of Northern Renaissance art.
Context: It is known that van Eyck was considered revolutionary within his lifetime; his designs and methods were heavily copied and reproduced. His motto, one of the first and still most distinctive signatures in art history, ALS IK KAN ("AS I CAN"), a pun on his name, first appeared in 1433 on Portrait of a Man in a Turban, which can be seen as indicative of his emerging self-confidence at the time. The years between 1434 and 1436 are generally considered his high point when he produced works including the Madonna of Chancellor Rolin, Lucca Madonna and Virgin and Child with Canon van der Paele. He married the much younger Margaret probably around 1432, about the same time he bought a house in Bruges; she is unmentioned before he relocated, while the first of their two children was born in 1434. Very little is known of Margaret, even her maiden name is lost - contemporary records refer to her mainly as Damoiselle Marguerite. She is thought to have been of aristocratic birth, though from the lower nobility, evidenced from her clothes in this portrait which are fashionable but not of the sumptuousness worn by the bride in the Arnolfini Portrait. Later, as the widow of a renowned painter Margaret was afforded a modest pension by the city of Bruges after Jan's death. At least some of this income was invested in lottery.  Van Eyck undertook a number of journeys on Philip the Duke of Burgundy's behalf between 1426 and 1429, journeys described in records as "secret" commissions, for which he was paid multiples of his annual salary. Their precise nature is still unknown, but they seem to involve his acting as envoy of the court. In 1426 he departed for "certain distant lands", possibly to the Holy Land, a theory given weight by the topographical accuracy of Jerusalem in The Three Marys at the Tomb, a painting completed by members of his workshop c. 1440.  A better documented commission was the journey to Lisbon along with a group intended to prepare the ground for the Duke's wedding to Isabella of Portugal. Van Eyck's was tasked with painting the bride, so that the Duke could visualise her before their marriage. Because Portugal was ridden with plague, their court was itinerant and the Dutch party met them at the out of the way castle of Avis. Van Eyck spent nine months there, returning to the Netherlands with Isabella as a bride to be; the couple married on Christmas Day of 1429. The princess was probably not particularly attractive, and that is exactly how Van Eyck conveyed her in the now lost portrait. Typically he showed his sitters as dignified, yet did not hide their imperfections. After his return, he was preoccupied with completing the Ghent Altarpiece, which was consecrated on 6 May 1432 at Saint Bavo Cathedral during an official ceremony for Philip. Records from 1437 say that he was held in high esteem by the upper ranks of Burgundian nobility and was employed in foreign commissions.

Background: Miranda was born Maria do Carmo Miranda da Cunha in Varzea da Ovelha e Aliviada, a village in the northern Portuguese municipality of Marco de Canaveses. She was the second daughter of Jose Maria Pinto da Cunha (17 February 1887 - 21 June 1938) and Maria Emilia Miranda (10 March 1886, Rio de Janeiro - 9 November 1971). In 1909, when Miranda was ten months old, her father emigrated to Brazil and settled in Rio de Janeiro, where he opened a barber shop.
Context: Desiring creative freedom, Miranda decided to produce her own film in 1947 and played opposite Groucho Marx in Copacabana. The film's budget was divided into about ten investors' shares. A Texan investor who owned one of the shares sent his brother, David Sebastian (23 November 1907 - 11 September 1990), to keep an eye on Miranda and his interests on the set. Sebastian befriended her, and they began dating.  Miranda and Sebastian married on 17 March 1947 at the Church of the Good Shepherd in Beverly Hills, with Patrick J. Concannon officiating. In 1948 Miranda became pregnant, but miscarried after a show. Although the marriage was brief, Miranda (who was Catholic) did not want a divorce. Her sister, Aurora, said in the documentary Bananas is My Business: "He married her for selfish reasons; she got very sick after she married and lived with a lot of depression". The couple announced their separation in September 1949, but reconciled several months later.  Miranda was discreet, and little is known about her private life. Before she left for the U.S., she had relationships with Mario Cunha, Carlos da Rocha Faria (son of a traditional family in Rio de Janeiro) and Aloysio de Oliveira, a member of the Bando da Lua. In the U.S., Miranda maintained relationships with John Payne, Arturo de Cordova, Dana Andrews, Harold Young, John Wayne, Donald Buka and Carlos Niemeyer. During her later years, in addition to heavy smoking and alcohol consumption, she began taking amphetamines and barbiturates and they took a toll on her health.
