Such is the chief difference in tone. In style, though the fact seems to have been little if at all noticed, there are two distinct species. There is the simple natural style of Letters I., II., and the rest, and there is the alembicated, tormented, precious, and affected style of Letters VIII. (III.) and IV. Have we any other examples, from Mary’s hand, of the obscure affectations of VIII. (III.) and IV.? Letter VIII., while it contains phrases which recur in the Casket ‘Sonnets,’ is really more contorted and _symboliste_ in manner than the verses. These ‘fond ballads’ contain, not infrequently, the same sentiments as the Letters, whether the Letters be in the direct or in the affected style. Thus, in Letter II., where Lady Bothwell and Mary’s jealousy of her are the theme, we read ‘Se not hir’ (Lady Bothwell) ‘quhais feinzeit teiris should not be sa mekle praisit or estemit as the trew and faithful travellis quhilk I sustene for to merite her place.’ Compare Sonnets ii. iii.: Brief je feray de ma foy telle preuve, Qu’il cognoistra sans faulte ma constance, Non par mes pleurs ou fainte obeyssance Comme autres font, mais par divers espreuve. In both passages the writer contrasts the ‘feigned tears,’ ‘feigned obedience’ of Bothwell’s wife with her own practical proofs of devotion: in the Sonnet using ‘them’ for ‘her’ as in Letter IV. A possible, but unexpected explanation of the extraordinary diversity of the two styles, I proceed to give. We have briefly discussed the Sonnets, which (despite the opinion of Ronsard) carry a strong appearance of authenticity, though whether their repetitions of the matter and phrasing of the Letters be in favour of the hypothesis that _both_ are authentic might be argued variously. Now from the Sonnets it appears that Lady Bothwell was endeavouring to secure her bridegroom’s heart in a rather unlooked-for manner: namely, by writing to him elaborately literary love letters in the artificial style of the age of the Pleiad. As the Sonnets say, she wooes him ‘par les escriptz tout fardez de sçavoir.’ But Mary maintains that Lady Bothwell is a mere plagiarist. Her ingenious letters, treasured by Bothwell, and the cause of his preference for her, are empruntés de quelque autheur luisant!
