Who is depicted as a false counselor and appears in Circle 8 Bolgia 8?

Guido da Montefeltro is depicted as a false counselor in Circle 8, Bolgia 8 of Dante's Inferno. In this part of the Inferno, Dante encounters those who gave false advice, leading others to harm. Guido's punishment exemplifies the consequences of his deceptive counsel. He was a notable figure who, though once wise, became ensnared in a web of ambition and ultimately employed his intelligence to lead others astray. When he appears before Dante, he recounts how he ended up in Hell after advising Pope Boniface VIII to deceive the enemy, highlighting the treachery associated with false counsel. His presence in this bolgia emphasizes Dante's condemnation of those who misuse their wisdom for selfish or deceitful purposes, making it clear that misleading guidance, even when cloaked in a façade of wisdom, has dire repercussions.
