In literature, birthmarks often serve an integral role as markers of identity. For example, in Cymbeline, Shakespeare’s tragedy about Celtic Britain, sinister Iachimo, after sneaking a glance of a sleeping unrobed Imogen, describes a distinctive (and usually hidden) mole under her breast, thus insinuating that they have had intimate relations. Similarly, in Arundhati Roy’s The God of Small Things,1(p70) a central character, Velutha, an Untouchable working for an upper-caste family, has, on his back, a “light-brown birthmark, shaped like a pointed dry leaf… that made the Monsoons come on time.” This cutaneous leaf instantly identifies Velutha, even when seen from behind.
