Adventure

The tale of +, -, ÷ and x

Resuming their journey, they’ll land in the City of Arabic numbers: will a new life await them there?

Jacopo Olivieri

Jacopo Olivieri was born in Verona in 1966. He spent his childhood between the countryside just outside the city and Ivory Coast, thanks to his father’s work (who was an architect and set designer). Since he was a child, he had a passion for reading and drawing, and he nurtured interests that are still reflected in his books: the imaginary in general, ancient legends, prehistoric animals, museums, monster stories, and exploring abandoned and mysterious places.

After finishing classical high school and a brief attempt at Natural Sciences at the University of Bologna, he pursued his first career as a comic book author. At the same time, he spent decades working in theater (set design, costumes) both in his home country and abroad and experimenting as an illustrator wherever he could (carton packaging, Swatch shops, educational publishing, records, toys…).

His life took a turn when he had the adventure of meeting Pierdomenico Baccalario, who proposed that he write books for children and young readers. Since then, he has published with Italy's major publishing houses, as well as a few abroad.
