How we cite our quotes: I cite by line number only in this module.
Quote #1
She walks in beauty (line 1)
This is a funny way of describing someone – what does it mean to "walk in beauty," anyway? Is "beauty" some kind of cloud or vapor that the woman is walking in? Or is it like a comfortable pair of shoes?
Quote #2
And all that's best of dark and bright
Meet in her aspect and her eyes: (lines 3-4)
This woman's beauty takes the "best" things from both ends of the spectrum ("dark" and "bright"). And it's not just that she has a pretty face – her whole "aspect," or appearance, is harmonious and lovely.
Quote #3
Thus mellow'd to that tender light
Which heaven to gaudy day denies. (lines 5-6)
The balance of "dark" and "bright" in the woman's appearance sort of averages out into a "tender light." It's like she casts off a glow, but a soft one, or something.
Quote #4
One shade the more, one ray the less, (line 7)
This line is perfectly balanced, just like the woman's beauty. There's a repeated structure, divided by a comma in the middle of the line – the comma is like a pivot point. You've got two sets of opposites ("shade" and "ray," "more" and "less") that are balanced on either side of that comma.
