Imperium Book 1: Graeculus: Volume 1

Imperium Book 1 is subtitled Graeculus, which means 'little Greek'. This nickname was given to the Emperor Hadrian, who eventually became the most powerful man in the Roman world. The book follows him through childhood, as he grew up Spain. His early interests in horses, hunting and the amphitheatre are all explored, as he becomes the ward of Trajan and eventually makes his way to live in Rome. The historical material is close to accurate throughout, though some characters have been invented to make life challenging, such as the rather nasty little donkey who bullies Hadrian's first horse.

The linguistic content of Book I includes nouns and adjectives in declensions 1 to 3, with verbs in the present active indicative, from conjugations 1 to 4.
