The Spanish Maze is a lost Jacobean stage drama whose author is unknown.
 It was performed at the court of King James I on 11 February 1605 by The King's Men, the acting company of William Shakespeare.
 It was one of ten plays performed there during the 1604-1605 holiday season, including seven by Shakespeare and two by Ben Jonson, and the only one of the ten now lost.
 A few scholars have suggested that "The Spanish Maze" was an early version of Shakespeare's "The Tempest".
Anarchist Manifesto (or The World's First Anarchist Manifesto) is a work by Anselme Bellegarrigue, notable for being the first manifesto of anarchism.

Saint Seiya: The Lost Canvas – The Myth of Hades (Japanese: Seinto Seiya Za Rosuto Kyanbasu - Meiō Shinwa ) , also known as simply The Lost Canvas, is a manga written and illustrated by Shiori Teshirogi.
 It is a spin-off based on the manga series "Saint Seiya", which was created, written and illustrated by Japanese author Masami Kurumada.
 "The Lost Canvas" was published by Akita Shoten in the "Weekly Shōnen Champion" magazine since August 24, 2006, concluding after 223 chapters on April 6, 2011, with twenty-five "tankōbon" released.
 Originally envisioned as a comic book whose purpose was to work simultaneously with Kurumada's "" as a multi-angle interpretation of the shared elements of its storyline, which stems from an event mentioned in Kurumada's original "Saint Seiya" manga; the approach was quickly abandoned, as both works greatly diverged, Kurumada's "Next Dimension" stayed as the canonical telling of these events, and "The Lost Canvas" as a separate alternate retelling.
