There is no real limit to the amount and variety of links which can be formed between the poem's many tales. The tale of Philomela may take us back to Pentheus, but is equally likely to make us reflect on Philomela's affinities with her fellow-weaver, Arachne, or with Scylla and her father, Nisus, who also shockingly transgresses their ties of kinship, and are similarly turned into birds to avoid bloodshed. It is common to talk of the Metamorphoses as a woven poem because the tales are so tightly enmeshed together; however, the nodes between them are almost inexhaustible and are not constrained by their locations in the poem, it is really more like a miniature world wide web than a tapestry. Of course, this analogy only works up to a point – it would be doing a disservice to Ovid's art to suggest that there is no significance in the ordering of his tales.
