СКАЧАТЬ in reactions to Meitzen’s suggestion that 19th-century parcel arrangements were a direct reflection of divisions established centuries earlier. Marc Bloch drew inspiration from Meitzen’s work, but situated his regressive method within a more dynamic view of history. Refusing to see the past as a still photograph, Bloch preferred a cinematic metaphor:

      If, then, the landscape is in a state of perpetual change, how can we justify the use of cadastral plans, modern or contemporary maps to study ancient or medieval forms? According to A. Verhulst, these documents constitute a valid source in cases where there is no doubt in the matter of historical sequentiality (Verhulst 1995, p. 20). In order to deduct the past from the present or, conversely, the present from the past, the observed state must be precisely situated within a logical progression. The feasibility of regressive studies is thus contingent on the conceptualization of this progression or sequence.

      In the 19th and the first half of the 20th century, evolutionism, as defined in the natural sciences, was seen as a coherent framework for describing change. Social scientists used these tools to compare different types of civilizations, based on an idea of progress, defined by Enlightenment philosophers as the ultimate goal for humanity. Evolution appeared to offer the means of attaining this goal, by means of a collective movement through a chain of states, with each clearly situated on a linear and cumulative timeline. Given a logical organization of time into a series of periods, it would then be possible to work backwards. In the words of Marc Bloch:

      The notion of age is ever-present in the study of morphology; some researchers expressed concern that the continued survival of past forms into the present might hinder the attainment of an optimum state by means of evolution. For Marcel Poëte, there was:

      The notion of age is also integral to the cycle of erosion concept in geomorphology, introduced by William M. Davis (1850–1934) and popularized in France by Henri Baulig (Masutti 2002). In this idealized model, landforms develop through a series of evolutions, step by step, finally resulting – when conditions allow – in a peneplain. The erosion cycle concept provides a means of explaining evolutions in a landscape. Under the effects of erosion, relief goes through a number of different “ages”, from youth to maturity and onto old age. Davis believed that, using this model, the past and future states of a relief form could be predicted based on observations of a present state (Meynier 1969, p. 58).

      Using this approach, Poëte analyzed the dynamics of a town or city by comparing it to a living being. Elements are transformed in one direction, from birth to death, making it possible to “discern the degree of evolution” at any given time (Poëte 2000, pp. 83–84). This logical sequence of known steps (birth, maturity, death) can be followed in both directions, to travel back in time (regressive history) and to improve our understanding of the present.

      Thus, historians may use the present to understand the past in the absence of source material for older periods. For geographers, on the other hand, incursions into the past give a better understanding of the present, and only the elements which are helpful for this purpose will be retained. In history, this approach is called “regressive”, whereas in geography, the term “retrospective” is used (Dion 1949). In both cases, time is considered as a continuous line, in which the present never completely eliminates legacies from the past. Past and present are linked by a logical chain, as Jean Brunhes and Camille Vallaux put it in their 1921 work examining the relationship between geography and history. For these authors, history offers the means of placing an isolated fact “into the stream of life which produced it”, as “one link in a chain” (Brunhes and Vallaux 1921, p. 21).

      1.2.4. Primary forms: a non-evolving landscape

      From the outset, however, the regressive analysis approach to history was confronted with a difficulty: that of studying landscapes which are in a constant state of evolution. Without a general framework for studying the evolution of human societies, it is hard to interpret plans or documents beyond their date of production. This led to a focus on planned parcel systems which marked a clear change from previous landscape patterns, for example following periods of land clearance. From a methodological perspective, a distinction was made between two types of landscape, of which A. Verhulst summarized the characteristics.

      The degree to which land systems were planned appears to have played a role in their fixation, limiting possibilities for future evolution, notably in the direction of plot inequality, since the plan covered the entirety of the townlands before they were put into agricultural use. Furthermore, the length and breadth of parcels were pre-defined from the outset. The limited scope for evolution in such cases facilitates reconstitution on the basis of later sources (Verhulst 1995, pp. 48, 52–53). In this case, the hardness (dureté) indicated by the persistence of architectural constructions (section 1.2.3) is a result of the planning process. As the historian СКАЧАТЬ
