Ingolstadt, Germany, lies on the Danube and Schutter Rivers, 45 miles north of Munich
                     and 30 miles south of Regensburg.
Records of this cultural and commercial center of Bavaria go back to the beginning
                     of the 9th century C.E. The city is surrounded by fourteenth-century walls, and is
                     distinguished by a ducal castle (1420), the Cathedral of Our Lady (1425-1500), the
                     Church of Maria de Victoria (1732-36). For centuries it was the seat of the Dukes
                     of Bavaria, who transferred to Munich only in 1800, leaving Ingolstadt a relatively
                     small provincial city (current population c. 90,000). The brief account in the 4th
                     edition of the Encyclopaedia Brittanica (1797), written before this event and roughly
                     contemporary with the timeframe of the novel, gives no hint of the town's impending
                     displacement.
A university was founded there in 1472, although it was moved to Landshut in 1800
                     and then to Munich in 1826. At the height of its importance in the Renaissance the
                     city and the university were a stronghold of Counter-Reformation orthodoxy.
In the eighteenth century an intellectual fervor of an opposite sort was centered
                     there, when a secret society, an offspin of the Masons self-styled the Illuminati,
                     was formed in Ingolstadt to consider the means to a revolutionary reconstruction of
                     European society. Although their actual effect was small, they constituted an easy
                     target for reactionary agitators who traced the debacle of the French Revolution to
                     this improbable source. The main purveyors of this reactionary propaganda were John
                     Playfair's Proofs of a Conspiracy Against All the Religions and Governments of Europe
                     (1797) and the Abbé Augustin Barruel's Mémoires pour servir à l'histoire du Jacobinisme
                     (1797). The latter volume was read by both Mary and Percy Bysshe Shelley in 1814-1815.
These and other similar works were the basis for a novel, with a long episode set
                     in Bavaria and drawing upon the secret society of Illuminati, written by Thomas Jefferson
                     Hogg, Shelley's roommate at Oxford, Memoirs of Prince Alexy Haimatoff (1813). Shelley
                     wrote the notice of the novel that appeared in the Critical Review in December 1814.
                     It is thus impossible for Mary not to have been well aware of the political contexts
                     in which she inserts her youthful protagonist.
