Sonnet 6 is an English or Shakespearean sonnet, constructed of three quatrains followed by a couplet, all in iambic pentameter, with the typical rhyme scheme of the English sonnet, ABAB CDCD EFEF GG. Most of the poem exemplifies the regular metrical alternation characteristic of iambic pentameter, as can be seen in the couplet:
× / × / × / × / × / Be not self-willed, for thou art much too fair × / × / × / × / × / To be death's conquest and make worms thine heir.
However, both these lines allow an alternative scansion, which may highlight a parallelism between "self-willed" and "death's conquest":
× × / / × / × / × / Be not self-willed, for thou art much too fair × × / / × / × / × / To be death's conquest and make worms thine heir.
Analysis
The opening line of this sonnet leads directly from the end of Sonnet 5, as though the two poems were intended as one, itself perhaps a reference to the idea of pairing through marriage that shapes the first 17 sonnets. The first line, “Then let not winters wragged hand deface,” also parallels Sonnet 64’s opening, “When I haue seene by times fell hand defaced.” The third line's sweet "vial" refers to the distillation of perfume from petals mentioned in Sonnet 5, but is now directly explained and expanded as an image of sexual impregnation in order to producechildren. In addition to the glass beaker, "vial" was also traditionally used of the womb: the OED cites John Lydgate’s invocation to the Blessed Virgin, “O glorious viole, O vitre inviolate.” The language of accounting is repeated from Sonnet 5. The image of "usury" refers to replication of the invested "essence" in offspring, in the same way that money earns interest. The propagation of children can never be exploitative. Shakespeare's own father had been accused in 1570 of usury, of charging 20% and 25% interest. Elizabethan divines preached uncompromisingly against usury in principle but often tolerated it in practice: the Act against Usury of 1571, while providing punishments for usury above and below 10%, unwittingly legitimized a standard interest rate of 10%. Thus, Shakespeare plays with tens, and a tenfold return on the investment is to be desired.
