The antux ‘rim’ that is being made for the shield of Achilles, mentioned here at I.18.479 and again at I.18.608, is triplax ‘threefold’, I.18.480, and the outermost fold or circle of this antux is the Ōkeanos, I.18.608. For Crates, as noted in the comment on I.18.478–609, this design representing the Ōkeanos is part of an overall cosmic allegory. In Eustathius Commentary on the Iliad vol. 4 p. 218 lines 14–17, the commentator draws attention to the morphological parallelism of triplax ‘threefold’ with diplax ‘twofold’, the second of which words refers at I.03.126 and at I.22.441 to a pattern-woven fabric. So, Eustathius recognizes here a crossover between the artistic worlds of metalwork and weaving. On the diplax, see already the comment on I.03.125–128. The epithet for antux ‘rim’ as marmareē ‘gleaming’ at I.18.480 is relevant, since the same word is attested as an epithet for the woven fabric that is called a diplax at both I.03.126 and I.22.441 in the medieval manuscript tradition. As we see from the attested medieval texts, the epithet marmareē ‘gleaming’ varies with porphureē ‘purple’ at both I.03.126 and I.22.441. For more on the interchangeable worlds of metalworking and weaving, see I.18.590 and the relevant comment on I.18.590–606.
