Ovason argues that previous translations have got it wrong, because they failed to realise that Nostradamus was writing in an esoteric language called the 'green language'. Where previous translations have seemed to stretch a point to make a quotation fit an historical event, Ovason reveals the prophet's true prophecies regarding the American and French revolutions, the Franco-Prussian, First, Second and Third world wars, earthquakes, floods, the Antichrist and the end of the world. Properly seen, Ovason argues, Nostradamus is the greatest Western prophet to commit his prophecies to writing since the Old Testament.
