"the books were written in the language the elements of which I had acquired at the cottage"

Paradise Lost (1674) by John Milton is an epic poem recounting the expulsion of Adam and Eve from the garden of Eden, considered a work of great importance in English literature.  The creature understandably subscribes to an interpretation popular at the time, particularly among the Romantics, in which Satan is not the villain but an eloquent and solitary antihero, rebelling against the injustices of his creator. 

Plutarch's Lives of the Noble Greeks and Romans (late-1st century AD) is a work of biography recounting the lives of famous men in Greek and Roman culture, and would provide the creature with a more or less continuous history of classical civilisation from the 2nd millenium BC to the 1st century AD.  However, the work freely mingles fact with fiction, containing biographies of mythical characters such as Theseus and Romulus as well as real historical figures, meaning that the picture it provided would be rather skewed.

The Sorrows of Young Werther (1787) by Johann Wolfgang von Goethe is a semi-autobiographical novel depicting a young German writer's unrequited love and resultant suicide.  The adolescent creature's identification with Werther reflects the book's enormous popularity amongst the contemporary youth who saw themselves in or styled themselves after its hero – this following included many of the Romantics and Napoleon Bonaparte (See note to page 39), who would later carry a copy with him while campaigning abroad.
