Juan José Arreola: Juan José Arreola Zúñiga (September 21, 1918 – December 3, 2001) was a Mexican writer and academic.  He is considered Mexico's premier experimental short story writer of the twentieth century.  Arreola is recognized as one of the first Latin American writers to abandon realism; he used elements of fantasy to underscore existentialist and absurdist ideas in his work.  Although he is little known outside his native country, Arreola has served as the literary inspiration for a legion of Mexican writers who have sought to transform their country's realistic literary tradition by introducing elements of magical realism, satire, and allegory.  Alongside Jorge Luis Borges, he is considered one of the masters of the hybrid subgenre of the essay-story.  He published only one novel, "La feria" (The Fair; 1963).

Essen cross with large enamels: The Cross with large enamels, or Senkschmelz Cross, known in German as the Senkschmelzen-Kreuz or the Kreuz mit den großen Senkschmelzen (Cross with large "senkschmelz" enamels) is a processional cross in the Essen Cathedral Treasury which was created under Mathilde, Abbess of Essen.  The name refers to its principal decorations, five unusually large enamel plaques made using the "senkschmelz" technique, a form of cloisonné which looks forward to champlevé enamel, with a recessed area in enamel surrounded by a plain gold background, and distinguishes it from three other crosses of the "crux gemmata" type at Essen.  The cross is considered one of the masterpieces of Ottonian goldsmithing.

Argenis: Argenis is a book by John Barclay.  It is a work of historical allegory which tells the story of the religious conflict in France under Henry III of France and Henry IV of France, and also touches on more contemporary English events, such as the Overbury scandal.  The tendency is royalist, anti-aristocratic; it is told from the angle of a king who reduces the landed aristocrats' power in the interest of the "country", the interest of which is identified with that of the king.

Bathsheba (Memling): Bathsheba (or The Toilet of Bathsheba After the Bath) are names given to a c 1480 oil on wood panel painting by the Early Netherlandish artist Hans Memling, now in the Staatsgalerie, Stuttgart.  Its unusually close framing and the fact that many of the details are cut off suggests that it is a fragment of a larger, probably religious, panel or triptych that was broken up.  The painting is noted for being a rare 15th century depiction of a nude person in northern renaissance art; such figures typically only appeared in representations of the "Last Judgement", and were hardly as deliberately erotic.  Memling is attributed one other secular nude portrait, in the center panel of his c. 1485 Vanitas allegory "Triptych of Earthly Vanity and Divine Salvation", at the Musée des Beaux-Arts, Strasbourg.

Watergate scandal: The Watergate scandal was a major political scandal that occurred in the United States in the early 1970s, following a break-in at the Democratic National Committee (DNC) headquarters at the Watergate office complex in Washington, D.C. on June 17, 1972, and President Richard Nixon’s administration’s attempted cover-up of its involvement.  When the conspiracy was discovered and investigated by the U.S. Congress, the Nixon administration’s resistance to its probes led to a constitutional crisis.
