Ars Amatoria
The Julian marriage laws of 18 BC, which promoted monogamous marriage to increase the population's birth rate, were fresh in the Roman mind. Ovid's writing in the "Ars Amatoria" concerned the serious crime of adultery. He may have been banished for these works, which appeared subversive to the emperor's moral legislation. However, in view of the long time that elapsed between the publication of this work (1 BC) and the exile (AD 8), some authors suggest that Augustus used the poem as a mere justification for something more personal.
