What are two allusions in "The Love Song of J. Alfred Prufock"?

The epigraph in Italian that opens the poem is a brief quotation from the 27th canto of Dante's Inferno. It is not cited or noted as being from Dante; Eliot uses it as a conceit to establish the idea that the speaker of the poem only consents to speak because he believes that what he has to say will never be repeated among the living, as is the case in Dante's Inferno.
In line 23, "and indeed there will be time" is an allusion to Andrew Marvell's 17th century poem "To His Coy Mistress." The speaker of Marvell's poem urges the object of his desire to give in to his advances because life is short. Prufrock, on the other hand, tries to convince himself that there will be plenty of time, because in Eliot's poem, the speaker is procrastinating when it comes to approaching attractive women.
