How we cite our quotes: (Line)
Quote #1
It had become a glimmering girl
With apple blossom in her hair (13-14)
By the speaker's description of the girl in these lines, we can guess that she's pretty beautiful. She's "glimmering" and she has "apple blossom" in her hair. Who can resist apple blossoms, right? This marks the moment in the poem when the speaker falls in love.
Quote #2
Who called me by my name and ran
And faded through the brightening air (15-16)
These lines give us a sense both of the seductiveness and elusiveness of the glimmering girl. She's flirting with Aengus (why else would she call his name?), but at the same time, she doesn't hang around. She disappears through the "brightening air." Part of the reason the speaker becomes so obsessed with this girl is because she's so elusive. She's there and then in a flash—poof—she's gone. Don't we always want what we can't have?
Quote #3
I will find out where she has gone,
And kiss her lips and take her hands (19-20)
This speaker is so obsessed, all he can think about is finding his elusive love and kissing her and holding her hands. The fact that the speaker's spent his whole life looking for this girl so he can kiss and hold her gives us a sense of just how deep his love is. He may have only seen her for a second, but he's fallen head over heels.
