The form of blason in John Fords Tis Pity Shes a Whore provides a venue for its protagonist, Giovanni, not only to voice his socially-prohibited longings for incestuous love but also to normalise his amoral and murderous rhetoric . Changes in its con-tents and styles reflect the changes in its users attitude towards social and cultural restrictions. The anachronism of the form of bla-son in the historical context of the plays performance also corresponds with Giovannis refusal to comply with contemporary social and moral codes. His insistence on employing this mode of speech can be interpreted as a means of self-justification in his struggle between the extal cultural norms and his intal call of nature.
