Question

Which quotation from Julius Caesar is an example of a literary allusion?

“I, as Aeneas our great ancestor / Did from the flames of Troy upon his shoulder / The old Anchises bear, so from the waves of Tiber / Did I the tirèd Caesar.” (act 1, scene 2)
"Pardon, Caesar; Caesar, pardon." (act 3, scene 1)
“He shall but bear them as the ass bears gold, / To groan and sweat under the business” (act 4, scene 1)
“Why, I will see thee at Philippi then.” (act 4, scene 3)

Answer 1

“I, as Aeneas our great ancestor / Did from the flames of Troy upon his shoulder / The old Anchises bear, so from the waves of Tiber / Did I the tirèd Caesar.” (act 1, scene 2)

This directly alludes to Aeneas carrying his father Anchises from the burning Troy (from Virgil’s Aeneid / classical myth), so it’s a literary/mythological allusion.
