book 2 of the Aeneid the L, C, and ŪC sounds of the word "light" are picked out and repeated: . "There was thunder on the left, and from the sky gliding through the darkness a star, drawing a trail, ran with much light." L can also suggest the gliding of liquid, as at Lucretius 5.950, where there is secondary alliteration of R: "from whom slippery streams flowing with moisture were learning how to wash the wet rocks with plentiful overflow" Both ideas are combined in the following lines, also from Lucretius: "Likewise, a plentiful spring of liquid light, the etherial sun, constantly irrigates the sky with fresh brightness." Echo alliteration Another use of alliteration in Virgil is to emphasise particular key words or names. Headlam (1921) demonstrates how when Virgil introduces a proper name he often uses echoes of the sound of that name through alliteration or assonance in nearby words, a technique he refers to as "echo alliteration": "and hundred-handed Briareus and the beast of Lerna" "Cassandra used to sing of such events." "Come hither, Father Lenaeus – here everything is filled with your gifts." "Priam ... Pergama". Not only proper names but also other key words can be highlighted in this way. In the passage below, the god Faunus and the wild olive tree () both play a significant role in the story. The first of these is highlighted by the alliteration F F F; the second by assonance (). There are further echoes in the syllables , , and in the second line: "By chance, sacred to Faunus, a wild olive with bitter leaves had stood here, a piece of wood once venerable for sailors." Dramatic moments Alliteration is frequently used in the Aeneid at moments of high drama, such as the moment that Aeneas's enemy Turnus is finally struck down by Aeneas in book 12. In this passage can be heard first the noisy STR STR imitating the sound of the spear's flight, then the vocalic alliteration of I I I as Turnus falls, and finally an assonance of PLI PLI as his knees buckle: "Whooshing, (the spear) passes through his thigh. The huge Turnus, struck, falls to the ground with folded knee." Another warrior dies in book 9 of the Aeneid as follows, with primary alliteration of V V, F F, and secondary alliteration of L L and NG NG: "He rolls over, vomiting
