Representations of the human body are ubiquitous in cultures across the world. Beyond the aesthetic, figurines transmit deeper meanings that were readily decodable by their intended audience and may still offer sociocultural insights despite the loss of this coding through time. The discovery of a rare tableau of ‘Bolinas’-type clay figurines dating to 410–380 BC at San Isidro, El Salvador, now permits the theoretical reconstruction of a less stratified Preclassic society in south-east Mesoamerica and the exploration of its spheres of interaction, which may have stretched along the coast from Guatemala to Costa Rica.
