After defining ‘real’ and ‘ideal’ in relation to character or behaviour and to setting, this chapter notes that, whereas the other four Greek ‘ideal’ novelists create a realistic background, whether using personal observation or historiography, Longus draws chiefly on literary texts that themselves present a fictional world (Homer and Theocritus) or one that is semi-fictional (archaic melic poetry). ‘The Country’ explores Longus’ debt to Theocritus’ landscape, especially that of Idyll 1, advertised by his preface as several steps removed from the real world. The chapter then discusses the relation of 2.32 to Theocritus 1; of 1.17.3 to Sappho and Anacreon via Theocritus 11, complicated by the term ἀληθῶς, ‘really’; and of the apple at 3.33.4 to Sappho’s epithalamia, Ibycus, and Theocritus 28. ‘The city’ explores the literary forebears of Longus’ Megacles; ‘The sea’ looks at his ‘Tyrian’ pirates’ origins in earlier novels, especially Chariton’s; and ‘Reality’ considers how his use of Thucydides underlines his own fictionality. Overall it is the chapter’s stress on the fictionality, rather than on the poetic status, of most of Longus’ intertexts that differentiates its writer’s position from those of Richard Hunter and Maria Pia Pattoni.
