If the ochre tradition has been correctly interpreted, it constitutes evidence for the world's first 'art'—an aspect of 'symbolic culture'—in the form of personal ornamentation and body-painting.[13] It was initially countered that pigment-only decorative systems are merely individualistic display, not necessarily indicative of ritual, whereas the bead traditions testify to language, institutionalised relationships and full-scale ritual and symbolic culture.[14][15] More recently, however, those making this criticism have conceded that the evidence for ochre pigment use, stretching back towards 300,000 years ago, must indeed be recognised as the earliest durable media testifying to a collective ritual tradition.[16]
