The chapter presents a case study on creolisation by analysing premodern Buddhist texts and the networks of Buddhist agents travelling along the ‘Silk Roads of the Sea’. It explores the trope of the wondrous aversion of a shipwreck narrated in Chinese and Tibetan Buddhist hagiographies, Sanskrit Sūtras, and the Classical Malay chronicle Sejarah Melayu. It notes that these accounts share similar narrative themes, like the miraculous intervention of a protective deity or the supernatural feats performed by the protagonist. Being characterised by a mix of verisimilar and imaginific elements, these narratives appear to reflect real and imagined anxieties about the perilous maritime journeys undertaken by monks and pilgrims. The mobility of this trope across different languages, literatures and geographical contexts matches the available material evidence of the circulation of texts and icons of protective deities across the Buddhist Cosmopolis.
