In this chapter, König examines an array of ‘literary interactions’ in Pliny’s 10th book of Letters. She draws particular attention to the book’s ‘heteroglossia’ – the multiplicity of linguistic registers and literary genres that it evokes and adopts – and she shows how that heteroglossia enables Pliny to accrue increasing authority and expertise as the book progresses. Starting with letters 10.1-14, she first explores intertexts between Pliny’s correspondence with Trajan and other close-contemporary literature (in particular, the Panegyricus and Frontinus’ De Aquis). Her focus then shifts to Pliny’s incorporation of a range of specialist discourses (architectural, religious, legal, financial, hydraulic, etc.) across the rest of the book, discourses which gradually flesh out his credentials as an administrator with the ability to command many different areas of government. She ends by exploring Pliny’s interaction with Trajan via an allusion to Pliny the Elder’s address to Titus at the start of his encyclopaedic Natural History. In drawing attention to the range and impact of different kinds of intertexts across Letters 10 – from specific textual allusions to generic interdiscursivity – she underlines what this seemingly ‘administrative’ correspondence can teach us about Roman reading and writing habits and the blurred boundary between ‘literary’ and non/less-‘literary’ texts.

Introducing the volume to come, this chapter explains the need for new approaches to the study of literary and cultural interactions in the Roman empire that cross linguistic, cultural and religious boundaries. It begins with a brief overview of the diversity of cross-cultural interactions that can be traced, on and off the page, between different individuals and communities in the second century CE. It analyses current and innovative methodologies for studying ‘intertextuality’ in different disciplines, including approaches that amplify gaps or silences, as well as instances of dialogue/cross-fertilisation. It then stresses three ways in which the volume particularly aims to contribute: firstly, by including technical, documentary, epigraphic and oral material in its wide-ranging study of ‘literary’ interactivity; secondly, by stressing the relationship between textual interaction, cultural practices and material aspects of empire; thirdly, by working out from intertextuality to interdiscursivity, shining a spotlight on the migration of ideas as well specific interactions. The introduction ends with a case study – the story of Arion and the dolphin, retold by many ancient authors – that exemplifies the processes of cross-cultural travel and transmission in the ancient world and also the challenges that scholars face in tracing and interpreting such cross-cultural interactions.

This chapter looks at two interconnected texts which were published within two or three decades of each other: Aelianus Tacticus’ Tactical Theory (addressed to Trajan) and Arrian’s Tactics, published two or three decades later under Hadrian. Both texts appear to draw on the same source material, and it is reasonable to suppose that Arrian was aware of Aelian’s earlier treatise, although there is no direct interaction between them. Their different approaches to the same material offer an opportunity to explore different models of literary and cross-cultural interaction, and also to examine our go-to metaphors and interpretative models for analysing them. While Aelian establishes a series of polemical comparisons between age-old Greek military theory and currently effective Roman military practice, Arrian hints at overlaps between Greek and Roman traditions, both by incorporating a section on Roman cavalry manoeuvres and by interacting with a speech delivered by Hadrian to the Roman army at Lambaesis in 128. Both approaches are equally tactical; and both are revealing of the complex dynamics of cross-cultural interaction, which took place on and off the page, and in literary and less literary forms of writing.
