Sixty years ago, on 25 April 1953, probably the most influential scientific article of the twentieth century appeared. Its uninviting title, ‘Molecular Structure of Nucleic Acids: A Structure for Deoxyribose Nucleic Acid’, concealed the revolutionary discovery by the molecular biologists James Watson and Francis Crick of the structure of what became known as ‘the molecule of life’. The ‘radically different structure’ that they proposed for the salt of deoxyribose nucleic acid (DNA) had ‘two helical chains each coiled round the same axis’. ‘Both chains’, they wrote, ‘follow right-handed helices, but owing to the dyad the sequences of the atoms in the two chains run in opposite directions.’ When Bruno J. Strasser asked in the same journal fifty years later ‘Who cares about the double helix?’, he answered that it marked ‘an age of (lost) innocence, when youth, intelligence and self-assurance were sufficient to make great discoveries in science’.

However, the very lack of inversion makes it not a chiasmus at all, but rather an isocolon, or direct parallelism (ABAB, rather than ABBA), on which see Martin, J., Antike Rhetorik.

Welch, ‘Chiasmus in Ancient Greek and Latin Literatures’, in Welch (n. 11), 264. Plato favours the interlocking and fully inverted form ABB´A´ (e.g. Plato, Resp. 6.494e: πᾶν μὲν ἔργον, πᾶν δ’ ἔπος λέγοντάς τε καὶ πράττοντας, ‘every deed, every word saying and doing’). The same words in the following order would be an example of reflecting chiasmus in the pattern AA´B´B: πᾶν ἔργον πράττοντας καὶ λέγοντας πᾶν ἔπος (‘every deed doing and saying every word’). The normal, non-chiastic arrangement of the same words would follow the pattern AA´B B´: πᾶν ἔργον πράττοντας καὶ πᾶν ἔπος λέγοντας (‘every deed doing and every word saying’).

Cesariano's error arose because he wrongly takes the word contra as ‘against’ rather than ‘opposite’ and thus interprets the corner elements as what contemporary architects called cantoni, consisting of pilasters with projecting and receding parts, instead of in the true ancient sense of a front row of columns standing apart from the antae.

67 Modern examples in literature are the use of the figure in Hamlet to focus on Gertrude's central decision whether or not to marry again after the death of Claudius, and the concentration of chiasmus in Book 3 of Milton's Paradise Lost to explore the relation between the justice of the Father and the mercy and love of the Son: see Clark (n. 47), 40–1.

72 If both statues faced the same way, the visitor entering the frigidarium would have seen both from behind; but if they faced opposite directions both the hero's front, wearied from his labours, and his rear side, revealing the apple of the Hesperides clasped behind his back, would have been visible simultaneously from either approach, alongside one another, and the views from inside and outside the frigidarium would have been in a chiastic relationship.
