In ‘Thou Fair Eliza’ he says:

Not the bee upon the blossom,
In the pride o’ sinny noon;
Not the little sporting fairy,
All beneath the simmer moon;
Not the minstrel, in the moment
Fancy lightens in his e’e,
Kens the pleasure, feels the rapture,
That thy presence gies to me.

In ‘My Bonie Bell’ he writes:

The smiling spring comes in rejoicing,
The surly winter grimly flies;
Now crystal clear are the falling waters,
And bonie blue are the sunny skies.
Fresh o’er the mountains breaks forth the morning,
The evening gilds the ocean’s swell;
All creatures joy in the sun’s returning,
And I rejoice in my Bonie Bell.

‘Sweet Afton’ was suggested by the following: ‘I charge you, O ye daughters of Jerusalem, that ye stir not, nor awaken my love—my dove, my undefiled! The flowers appear on the earth, the time of the singing of birds is come, and the voice of the turtle is heard in the land.’

In descriptive power and in fond and reverent love no poem of Burns, or any other writer, surpasses Sweet Afton. Authorities have been divided in regard to the person who was the Mary of Sweet Afton. Currie and Lockhart declined to accept the statement of Gilbert Burns that it was Highland Mary. Chambers and Douglas, the most illuminating and reliable of the early biographers of Burns, agree with Gilbert. One of Mrs Dunlop’s daughters stated that she heard Burns himself say that Mary Campbell was the woman whose name he used to represent the lover for whom he asked such reverent consideration. He had no lover at any period of his life on the Afton. He had but one lover named Mary, and she stirred him to a degree of reverence that toned the music of his love to the end of his life. Mary Campbell was alive to Burns in a truly realistic sense when he wrote the sacred poem ‘Sweet Afton.’

In ‘O were my Love yon Lilac Fair’ he assumes that his love might be

A lilac fair,
Wi’ purpling blossoms in the spring,
And I a bird to shelter there,
When wearied on my little wing.

In the second verse he says:

O gin my love were yon red rose if
That grows upon the castle wa’;
And I mysel’ a drop o’ dew,
Into her bonie breast to fa’!
