Presumably, this quatrain is about Napoleon I (15.08.1769 – 05.05.1821).

The 1 line. He was born on the island Corsica, which is located near Italy. There was no royal blood in his ancestry. His parents were petty aristocrats. Nevertheless, he became one of the most famous king. Few people know anything about Louis V or X, but everybody heard of Napoleon.

The 4 line. Endless Napoleonic wars led to the destruction of a large part of the population, not only in Europe and Africa but also in France itself. By the end of his reign there was almost no male population left in the country fit for the military service. Napoleon had to recruit teenagers.

Linkage with other quatrains: 4.54, 8.57, 1.76, 8.59, 8.53, 6.12, 9.86.

Probable decoding of number 1.60. 1000-60=940, 9-1=8, If 40 swap in 04 we will get 804 – the year of reign.

Quatrain 5.5 Napoleon poet

Sous ombre saincte d'oster de seruitude,

Peuple & cité l'vsurpera luy-mesmes,

Pire fera par faux de ieune pute,

Liuré au champ lisant le faux proesme. E iij

Under the shadowy pretext of removing servitude,

He will himself usurp the people and city:

He will do worse because of the deceit of the young prostitute,

Leader in the field reading the false poem.

The first two lines are about the career of Napoleon I. At first he pretended to support the ideas of the Revolution. When he became the head of the army, he usurped the power, established the monarchy, not having hereditary right.

The third line is perhaps about Josephine Beauharnais, Napoleon’s wife. She led a free way of life. The lover Napoleon, being in Egypt, was very upset when he learned of her infidelity.
