We refer to some of the ideas of David Bohm (1989, 1992, 1994, 1996) to support our theoretical understanding about the operation of thought. We chose a period that is recognized by the theorists as the origin of the geometrical thought -embracing the knowledge developed by the Egyptians, Babylonians, Chinese, Hindus, Greeks and Romans- and is referred to as containing a cycle in the development of this knowledge, described as beginning, apogee and decline. We assume this history, as told by the theorists, as a version that we organize and tell with the help of three sets of categories. The first refers to the elements that take part in the measurement practices; the second refers to the historians understanding about the development of the scientific knowledge. This exercise allowed us to extract the theorists main beliefs, that we criticized in the light of the knowledge about Cuba??o (Dal Pian, 1990). We stress the importance of the methodological approach adopted in this study to the teaching of Geometry and its history / Este trabalho se prop?e a investigar a din?mica do pensamento dos historiadores ao comporem um conhecimento sobre hist?ria dos sistemas de medidas de ?rea, enquanto formas de express?es e representa??es hist?ricas, atrav?s de um estudo de caso. Para subsidiar teoricamente o nosso entendimento sobre a opera??o do pensamento, recorremos a algumas id?ias de David Bohm (1989, 1992, 1994, 1996). Elegemos um per?odo reconhecido pelos te?ricos como contendo as origens do pensamento geom?trico -abrangendo os conhecimentos desenvolvidos pelos eg?pcios, babil?nios, chineses, hindus, gregos e romanos- e referido como comportando um ciclo de desenvolvimento desse conhecimento, descrito como inicia??o, apogeu e decl?nio. Assumimos essa hist?ria, tal como contada pelos te?ricos, como uma vers?o, que organizamos e relatamos com o aux?lio de tr?s conjuntos de categorias. Um referente aos elementos envolvidos nas pr?ticas de mensura??o, outro referente ao entendimento dos historiadores sobre o desenvolvimento do conhecimento geom?trico e o terceiro, referente ? natureza do desenvolvimento do conhecimento cient?fico. Este exerc?cio nos possibilitou extrair as principais cren?as dos te?ricos que criticamos ? luz do conhecimento sobre cuba??o (Dal Pian, 1994). Destacamos a import?ncia da abordagem metodol?gica adotada neste estudo para o ensino da geometria e de sua hist?ria
