The almost simultaneous publication of two compendiums of the history of medieval political thought, both proposed by Italian scholars, is at the origin of this section of discussion proposed to the readers of “Reti Medievali Rivista”. We wanted to entrust this comparison to three historians coming not only from different academic schools, but from specific and different cultural sensibilities. It has been chosen to involve three non-Italian scholars also because the historiographical and editorial landscape has not been recording for many years a similar proposal of historical synthesis or a similar didactic effort. This can be seen by observing both European and cross-Atlantic publishing. Scordia, Nederman and Juncosa have highlighted several innovative elements of the two profiles at the center of the discussion, noting specificities (e.g. the new approach to the role of political aristotelism), differences (the contribution of legal wisdom, the role of Brunetto Latini, the chronological period investigated) and inevitable shortcomings, also due to the editorial cut of the works. From this point of view it has been emphasised the underestimation of the contribution coming from some European territories and of some issues such as, for example, the role of representative assemblies. All three have instead agreed to highlight an originality that can be defined as a real advance conquered by the two volumes on the heuristic and educational level: the ability to put texts into dialogue, their genesis, their specific theoretical contribution, with their respective historical contexts. The dossier closes with a fourth contribution that contains a series of observations on the two important compendiums and a proposal aimed at including some specific types of sources in the list of those used to trace the history of powers thought in the Middle Ages and, therefore, to make the history of medieval political thought. The proposal focuses on the textuality that discusses the ownership and statute of the currency and the legal texts defining the personal nature of property taxes.
