It is worth noting that, although some of the authors featured in this quiz might not be considered strictly "Italian", most of them were born, spent a significant portion of their lives, and/or had a strong multifaceted connection with the territory corresponding to modern-day Italy and other Italian-speaking nations. Additionally, in terms of vernacular affinity, it could be reasonably assumed that they wrote primarily (more often than not exclusively) in the Italian language (including archaic variations of it). All things considered, while their mentioning could be understandably debatable, it would also be justified to a certain degree.
