Pallas and the Centaur by Linda Proud

Pallas and the Centaur is the second part of ‘The Botticelli Trilogy.’ Following the Pazzi Conspiracy, Florence finds itself at war with Rome and Naples. Lorenzo de' Medici, whose brother was murdered by the Pazzi, has no doubt that he has God on his side. His wife, Clarice, is not so sure. Roman-born and pious she is in every way a medieval woman and believes that the troubles besetting the family are due to Lorenzo's 'heresy', that is, his Platonism. Lorenzo sends her to safety, under the protection of Angelo Poliziano. Powerless against her husband, Clarice sets out to destroy the poet.

The domestic conflicts reflect – in fact, are intimately connected with – world affairs. As Lorenzo's marriage falls apart, so does his hold on the power-politics of Florence and Italy. Events move to dramatic conclusions that explode each character's beliefs and certainties.
The war is not just between Florence and Rome but is a battle between the medieval world and the Renaissance, between superstitious Christianity and Christian Platonism, between faith and reason, between a woman and a man. It is the battle of Juno and Zeus.
