[2] Luca Assarino was born on 18 October 1602 in Potosí,[3]: 13 his father was from Liguria and his mother a Portuguese.
After another charge of murder, of his father-in-law, he was sentenced to three years of imprisonment in Savona, he escaped and his wife bailed him.
In 1646 he became editor of the newspaper Genova (known as Il Sincero for the additional title that sometimes appeared under his management), a job he carried out until 1660 along with the writing of hand-writing newssheets, which he used to sell at high prices.
[5] In 1649, due to his pro-French leanings, he was appointed official historiographer of the Duchy of Savoy thanks to Christine of France.
After going back to Milan he published his most important historical work Delle guerre e successi d'Italia (in English: Of the wars and events of Italy), which had a reasonable success, even if nowadays it is considered partisan and not accurate.
