This article traces the figure of the lūṭī in the writings of Ibn Qayyim al-Jawziyyah (d. 1350) and Ibn Kathīr (d. 1373). These two fourteenth-century scholars adopted a harsh and uncompromising view of the lūṭī as a sexual actor, repeatedly depicting the horrific afterlife punishments awaiting him in Hell. As part of their hyperbolic and extreme depiction of the lūṭī as a damned sexual figure, they imagine him through his communal relationship to his forebears, both among the Qur’anic People of Lūṭ and those like him in his present day. They thereby construct a sexual community of sorts, framing the lūṭī through a parodic repurposing of a strikingly Islamic idiom of belonging and community-building. In doing so, I argue, these texts open up broad possibilities for us to rethink how medieval authors theorised what we might call ‘sexual identity’ and understood sex to construct ways of being in the world around them.
