In "The Wars of the Roses," Alison Weir presents Virgil's perspective on the consequences of sin across generations, particularly regarding the English monarchy. He believes that the transgressions of Henry IV have repercussions for his descendant, Henry VI. This idea reflects a sense of moral continuity and divine justice within the royal lineage.

However, Virgil's theory raises questions, especially when it comes to the successful reign of Henry V. His achievements seem to contradict the notion of divine punishment, implying a complex relationship between a ruler's virtue and the legacy of their ancestors. This contradiction invites deeper reflection on the nature of fate and morality in historical contexts.
