In 20th century, at Thessaly region a series of paradigmatic metamor-phoses took place that transformed both the spatial and environmental aspects of this landscape. Focusing on Thessaly’s environmental and spatial peculiarities and exploring the region’s human footprint this paper proposes a methodology that underlines their significance in the context of Anthropocene. The methodological tool is an ongoing dictionary of terms – textual & visual – exported from the specific territory and contributing to a wider observatory of Anthropocene. The methodol-ogy of the dictionary is applied not only as an accredited tool of terminological mapping, but also as a critical interpretation mechanism through which we will be able to perceive current and future changes of our living environments.
