Skeuomorphs are copies of prototype artifacts replicated in different physical materials in the derivative objects. The skeuomorph copy may or may not have a utilitarian function, and the original function of the prototype attribute may change or become less functional with successive copying. Because skeuomorphs are an imitation of the prototype model, they are iconic representations. Archaeological examples of pottery vessel skeuomorphs are presented and interpreted with evidence from ethnography, psychology, and modern material culture. This review lends support to the proposal that skeuomorphism is a causal factor in technological change. Skeuomorphs facilitate acceptance of innovations in artifacts by (1) materializing the pre-existing familiar value of prototypes as attributes transferred to unfamiliar derivative objects; (2) evoking positive social memories associated with the prototype; and (3) creating broader scales of value by creating novel variants of similar objects.

La copia esqueumorfa puede o no tener una función utilitaria, y la función original del atributo prototipo puede cambiar o llegar a ser menos funcional con copiado sucesivo. Debido a que esqueumorfos son una imitación del modelo prototipo, ellos son representaciones icónicas. Ejemplos arqueológicos de vasos de cerámicas esqueumorfas son presentados e interpretados con evidencia de etnografía, psicología, y cultura material moderna.Con esta revisión, presté apoyo a la propuesta que esqueumorfismo es un factor causal en cambio tecnológico. Los esqueumorfos facilitan la aceptación de las innovaciones en artefactos al (1) materializar el preexistente valor familiar de los prototipos como atributos transferidos a objetos derivativos no reconocidos; (2) evocar memorias sociales positivas asociadas con el prototipo; y (3) crear escales más amplias de valor diseñando variantes innovadoras de objetos similares. [esqueumorfo, cerámica, cambio tecnológico, arqueología] T he claim that the shapes and surface treatments of early ceramic containers were copies-skeuomorphs-of nonceramic containers is an old observation with considerable history, but U.S. archaeologists rarely discuss its significance for understanding technological change within the archaeological record. Most researchers privilege utilitarian or economic factors in the innovation and adoption of ceramic vessels and other artifacts. I propose that skeuomorphs, which include designs unrelated to utilitarian needs, were instrumental in the acceptance of innovations such as pottery. In presenting this interpretation of the role of skeuomorphs in the innovation and adoption of pottery, I review evidence from archaeology, ethnology, and experimental psychology.First, I introduce skeuomorphism and identify ceramic vessel skeuomorphs. Next, I review archaeological approaches to technological change and consider ...
