Final answer:
The question seems to be mixing different narrations; one about an unnamed shepherd boy who later became a soldier in the Roman army, and one about Andean herding practices. The name of the boy and the time spent as a shepherd, as well as the specific region in Spain, are not identified in the given narratives.
Step-by-step explanation:
The specific details regarding the shepherd boy are not provided, suggesting that this may be from a historical context or a narrative that requires identifying a figure based on character traits rather than a specific person called by name. No name is provided for this shepherd boy, who according to the information, has had a varied life. His early youth was spent as a shepherd with a noble appearance. Later, he engaged in raids with bandits, provided protection against attacks, and then joined the Roman army, serving in the cavalry. It is clear from this description that he was a young man of remarkable character, being brave, handsome, harsh, arrogant, contemptuous, but, above all, just.
The information provided does not mention a specific region in Spain but rather a pastoral context involving the Andean community and their relationship with the flock, which might not be connected to the initial character. Within this community, herding is considered a gift from Pachamama (Mother Earth). There is a mention of a unique belief in the librito (little book), which is believed to hold the life details of an animal within the herd and is interpreted through the animal's behavior by the herders.
