In the First Folio, the plays of William Shakespeare were grouped into three categories: comedies, histories, and tragedies. The histories—along with those of contemporary Renaissance playwrights—help define the genre of history plays. The Shakespearean histories are biographies of English kings of the previous four centuries and include the standalones King John, Edward III and Henry VIII as well as a continuous sequence of eight plays. These last are considered to have been composed in two cycles. The so-called first tetralogy, apparently written in the early 1590s, covers the Wars of the Roses saga and includes Henry VI, Parts I, II & III and Richard III. The second tetralogy, finished in 1599 and including Richard II, Henry IV, Parts I & II and Henry V, is frequently called the Henriad after its protagonist Prince Hal, the future Henry V.

In Shakespearean scholarship, Henriad refers to a group of William Shakespeare's history plays. It is sometimes used to refer to a group of four plays, but some sources and scholars use the term to refer to eight plays. In the 19th century, Algernon Charles Swinburne used the term to refer to three plays, but that use is not current.

A pentalogy is a compound literary or narrative work that is explicitly divided into five parts. Although modern use of the word implies both that the parts are reasonably self-contained and that the structure was intended by the author, historically, neither was necessarily true: in fact, a pentalogia could be assembled by a later editor, just as Plotinus's Enneads were arranged in nines by Porphyry in order to create an overarching structure of six which would express the idea of perfection.
History is one of the three main genres in Western theatre alongside tragedy and comedy, although it originated, in its modern form, thousands of years later than the other primary genres. For this reason, it is often treated as a subset of tragedy. A play in this genre is known as a history play and is based on a historical narrative, often set in the medieval or early modern past. History emerged as a distinct genre from tragedy in Renaissance England. The best known examples of the genre are the history plays written by William Shakespeare, whose plays still serve to define the genre. History plays also appear elsewhere in British and Western literature, such as Thomas Heywood's Edward IV, Schiller's Mary Stuart or the Dutch play Gijsbrecht van Aemstel.

I have always had a romantic idea that the writer or the artist was, as Coleridge and Virginia Woolf said, androgynous. The whole of The Virgin in the Garden quartet is about the desirability of an androgynous mind... JN & JF: I notice that the quartet which begins with The Virgin in the Garden is sometimes called The Frederica Quartet. ASB: My paperback publisher, you will be glad to hear, is going to make it a boxed set, and it's just going to be called The Quartet. It isn't Frederica's book--though she's the sort of person who would muscle in and try to take it!
