Sommario/riassunto |

The reconstruction of Roman mining activities in a primary deposit during the 1st and 2nd centuries AD has been made possible thanks to the excellent preservation of ancient mining and the prerequisite accompanying industries in the territorium metallorum Tresminas / Jales. Decades of on-site research and careful documentation of the monuments have faciliated the understanding of the work processes presented in this volume: prospection, excavation and processing. Within this framework, prospecting not only served the discovery of deposits as reported by ancient sources, but it accompanied the miners' daily work and was an essential element of the mining process. A special insight into the conditions in an ancient mine is given by the evidence of a catastrophe underground with a subsequent rescue operation. The mining itself has left traces that enable us to both follow and understand the progress of mining over time. The planning and execution that become visible as a result of this allow us to infer a central organisation. The fantastic extensive high galleries of Tresminas, whose dimensions and state of preservation still impress visitors and researchers today are a further example of this. Finds that were abandoned, never completed or destroyed in ancient times are particularly helpful in understanding the mining process. The complex |

processing of the gold-bearing ores has left behind in Tresminas around 1 000 stamp mills, countless rock-grinding mills and enormous ore washing structures. In addition, the water management system associated with mining and settlement is discussed. An important part of the industrial complex was also the local stone quarrying for the production of stamp mills, rock-grinding and grain mills. A summary of the historical context of the territorium metallorum Tresminas / Jales is presented in the introduction. An important contribution to further research into the ancient Greek and Roman economic history, Archaeology of mining and history of technology. |

Sommario/riassunto |
|
L’histoire économique des pêches maritimes rappelle le caractère particulier de cette industrie, celui d’une activité de cueillette. L’intérêt des économistes pour l’analyse des pêches maritimes relève autant du thème de l’exploitation des ressources marines vivantes que de leur surexploitation. Il existe aussi une autre porte d’entrée à la |

connaissance des pêches, celle d’un sentier de dépendance emprunté par les acteurs de l’industrie. Les situations rencontrées dans l’histoire économique contemporaine des pêches maritimes françaises, de 1983 à 2013, montrent qu’effectivement il n’existe pas un sentier unique et que les politiques publiques d’encadrement des flottilles ont davantage emprunté un régime de transition qu’un régime de rupture. Cet ouvrage rappelle les évènements clés de l’histoire récente des pêches maritimes, comme éléments structurants des relations des marins pêcheurs avec leurs institutions. La mise en place d’une politique commune de la pêche en 1983 modifie progressivement le format des flottilles en dessinant une trajectoire le long de laquelle se créent des relations de dépendance entre la profession et l’État. L’ouvrage décrit l’évolution de la population de marins pêcheurs, des flottilles et des productions débarquées au cours des trois dernières décennies pour les ports de métropole et de Saint-Pierre et Miquelon. |
