Having heard the reason for Romeo's depression and general love-sick attitude, Benvolio, desperate to try and cheer his friend up, tries to tempt him to go to the Capulet's feast. However, the only thing that helps him to entice Romeo along is the assurance that Romeo's lover, Rosaline, will be there, and that Benvolio will show Romeo how there are so many more beautiful women at this feast than Rosaline:
At this same ancient feast of Capulet's
Sups the fair Rosaline whom thou so lovest,
With all the admired beauties of Verona:
Go thither; and, with unattainted eye,
Compare her face with some that I shall show,
And I will make thee think thy swan a crow.
Although Romeo marks out Benvolio's hope as being impossible, at the same time he agrees to go to the feast so that he can rejoice in the beauty of his lover and be near to her. It is interesting though that, as important as Rosaline is in these first scenes, she never appears at the banquet or indeed in the play as a whole, seeming to be included in the play to show Romeo's swift change in his affections from Rosaline to Juliet.
