History of Purgatory: The idea of purgatory has roots that date back into antiquity.  A sort of proto-purgatory called the "celestial Hades" appears in the writings of Plato and Heraclides Ponticus and in many other pagan writers.  This concept is distinguished from the Hades of the underworld described in the works of Homer and Hesiod.  In contrast, the celestial Hades was understood as an intermediary place where souls spent an undetermined time after death before either moving on to a higher level of existence or being reincarnated back on earth.  Its exact location varied from author to author.  Heraclides of Pontus thought it was in the Milky Way; the Academicians, the Stoics, Cicero, Virgil, Plutarch, the Hermetical writings situated it between the Moon and the Earth or around the Moon; while Numenius and the Latin Neoplatonists thought it was located between the sphere of the fixed stars and the Earth.

Copyright expiration in Australia: Copyright expiration in Australia depends on when a work was created, and on the type of work.  Under the current law, copyright usually expires 70 years after the death of the author, or for anonymous works, 70 years from the date of publication.  Crown copyright expires 50 years after publication.  The law has evolved over the years, and previously photographs were treated differently from other works.  Anonymous works and photographs created before 1955 are no longer under copyright.  For non-photographic works created before 1955, where the author is known, the copyright expires 50 years after the death of the author.

Euphorion (playwright): Euphorion (Greek: Εὐφορίων , "Euphoríōn") was the son of the Greek tragedian Aeschylus, and himself an author of tragedies.  In the Dionysia of 431 BCE, Euphorion won 1st prize, defeating both Sophocles (who took 2nd prize) and Euripides, who took 3rd prize with a tetralogy that includes the extant play "Medea".  He is purported by some to have been the author of "Prometheus Bound"—previously assumed to be the work of his father, to whom it was attributed at the Library of Alexandria,—for several reasons, chiefly that the playwright's portrayal of Zeus is far less reverent than in other works attributed to Aeschylus, and that references to the play appear in the plays of the comic Aristophanes.  This has led historians to date it as late as 415 BCE, long after Aeschylus's death.  If Euphorion wrote "Prometheus Bound", there are as a result five ancient Greek tragedians with one or more fully surviving plays: Aeschylus, Euphorion, Sophocles, Euripides, and the unknown author of the tragedy Rhesus.

Eliza Rennie: Eliza Rennie or Mrs. Eliza Walker is a published author, though her biography remains somewhat of a mystery.  She was possibly born 17 May 1813, although this is uncertain and unproven.  Her death date was sometime after 30 Mar 1869, when she was awarded £25 by the Royal Literary Fund.  Eliza was a minor Scottish-born romantic/gothic short story author, who spent most of her adult life in London, and published an autobiographical two-volume work of literary gossip "Traits of Character: being Twenty-Five Years' Literary and Personal Recollections, by a Contemporary".  She was most notable for writing about her friendship with Mary Shelley and her contemporaries, including meetings with such celebrities as the Duke of Wellington.
