By the 19th century, scholars had found Tristan legends spread across the Nordic world, from Denmark to the Faroe Islands. These stories, however, diverged greatly from their medieval precursors. In one Danish ballad, for instance, Tristan and Iseult are made brother and sister. Other unlikely innovations occur in two popular Danish chapbooks of the late 18th-century "Tristans saga ok Inionu" and "En tragoedisk Historie om den ædle og tappre Tistrand", in which Iseult is made the princess of India. The popularity of these chapbooks inspired Icelandic poets Sigurður Breiðfjörð and Níels Jónsson to write rímur, long verse narratives, inspired by the Tristan legend.
