input: In 1852 he entered the Royal Academy of Antwerp in Belgium where he studied early Dutch and Flemish art, under Gustaf Wappers. During Alma-Tadema's four years as a registered student at the Academy, he won several respectable awards.  Before leaving school, towards the end of 1855, he became assistant to the painter and professor Louis (Lodewijk) Jan de Taeye, whose courses in history and historical costume he had greatly enjoyed at the Academy. Although de Taeye was not an outstanding painter, Alma-Tadema respected him and became his studio assistant, working with him for three years. De Taeye introduced him to books that influenced his desire to portray Merovingian subjects early in his career. He was encouraged to depict historical accuracy in his paintings, a trait for which the artist became known.  Alma-Tadema left Taeye's studio in November 1858 returning to Leeuwarden before settling in Antwerp, where he began working with the painter Baron Jan August Hendrik Leys, whose studio was one of the most highly regarded in Belgium. Under his guidance Alma-Tadema painted his first major work: The Education of the children of Clovis (1861). This painting created a sensation among critics and artists when it was exhibited that year at the Artistic Congress in Antwerp. It is said to have laid the foundation of his fame and reputation. Alma-Tadema related that although Leys thought the completed painting better than he had expected, he was critical of the treatment of marble, which he compared to cheese.  Alma-Tadema took this criticism very seriously, and it led him to improve his technique and to become the world's foremost painter of marble and variegated granite. Despite any reproaches from his master, The Education of the Children of Clovis was honorably received by critics and artists alike and was eventually purchased and subsequently given to King Leopold of Belgium.

Question: Aeschylus (UK: , US: ; Greek: Aiskhulos Aiskhulos; Ancient Greek: [ais.khy.los]; c. 525/524 - c. 456/455 BC) was an ancient Greek tragedian. He is often described as the father of tragedy. Academics' knowledge of the genre begins with his work, and understanding of earlier tragedies is largely based on inferences from his surviving plays.

Aeschylus continued his emphasis on the polis with The Suppliants in 463 BC (Hiketides), which pays tribute to the democratic undercurrents running through Athens in advance of the establishment of a democratic government in 461. In the play, the Danaids, the fifty daughters of Danaus, founder of Argos, flee a forced marriage to their cousins in Egypt. They turn to King Pelasgus of Argos for protection, but Pelasgus refuses until the people of Argos weigh in on the decision, a distinctly democratic move on the part of the king. The people decide that the Danaids deserve protection, and they are allowed within the walls of Argos despite Egyptian protests.  The 1952 publication of Oxyrhynchus Papyrus 2256 fr. 3 confirmed a long-assumed (because of The Suppliants' cliffhanger ending) Danaid trilogy, whose constituent plays are generally agreed to be The Suppliants, The Egyptians and The Danaids. A plausible reconstruction of the trilogy's last two-thirds runs thus: In The Egyptians, the Argive-Egyptian war threatened in the first play has transpired. During the course of the war, King Pelasgus has been killed, and Danaus rules Argos. He negotiates a peace settlement with Aegyptus, as a condition of which, his fifty daughters will marry the fifty sons of Aegyptus. Danaus secretly informs his daughters of an oracle predicting that one of his sons-in-law would kill him; he therefore orders the Danaids to murder their husbands on their wedding night. His daughters agree. The Danaids would open the day after the wedding.  In short order, it is revealed that forty-nine of the Danaids killed their husbands as ordered; Hypermnestra, however, loved her husband Lynceus, and thus spared his life and helped him to escape. Angered by his daughter's disobedience, Danaus orders her imprisonment and, possibly, her execution. In the trilogy's climax and denouement, Lynceus reveals himself to Danaus, and kills him (thus fulfilling the oracle). He and Hypermnestra will establish a ruling dynasty in Argos. The other forty-nine Danaids are absolved of their murderous crime, and married off to unspecified Argive men. The satyr play following this trilogy was titled Amymone, after one of the Danaids.
