A small bronze tablet, found at Bembibre (El Bierzo, León) in 1999, carrying an edict of Augustus dated to 15 BC — the earliest dated document of the Roman administration of north-western Hispania after the Cantabrian and Asturian Wars. Augustus, styling himself in his ninth tribunician year and proconsul, declares that the castellani Paemeiobrigenses, a community of the gens of the Susarri, remained loyal (in officio) while the rest revolted; he therefore grants them perpetual immunity (immunitas) and confirms their possession of their lands, as held under his legate Lucius Sestius Quirinalis, governor of the short-lived Transduriana provincia. In a second provision he substitutes for them the castellani Aiiobrigiaecini, of the gens of the Gigurri, who are now to discharge every public burden together with the Susarri. The bronze is dated 'at Narbo, on the 16th and 15th day before the Kalends of March' (14-15 February) in the consulship of M. Drusus Libo and L. Calpurnius Piso. The text is central to the debate over the imperium proconsulare of the princeps and over the castellum/gens structure of the Astur-Callaecian north-west.1999年于莱昂之本比夫雷（比埃尔索地区）出土之小铜板，载奥古斯都公元前15年之敕令——乃坎塔布里与阿斯图里亚战争之后、罗马治理西班牙西北部之最早有确切纪年之文献。奥古斯都自署「保民官权第九年、代行执政官（proconsul）」，宣告苏萨里部族（gens Susarrorum）之帕埃梅奥布里吉聚落（castellani Paemeiobrigenses）于他人叛乱之际坚守其忠（in officio）；故赐其永久豁免（immunitas），并确认其在其副将、Transduriana 行省总督卢基乌斯·塞斯提乌斯·奎里那利斯治下所占有之土地。其次，敕令以吉古里部族（gens Gigurrorum）之 Aiiobrigiaecini 聚落代之，使后者与苏萨里人共担一切公共义务。铜板纪年作「行于纳尔波，三月朔前第十六、十五日」（即2月14–15日），时为德鲁苏斯·利波与卡尔普尔尼乌斯·皮索任执政官之年。本铭对元首「代行执政官治权」（imperium proconsulare）之争论，及西北 Astur-Callaecia 之 castellum／gens 结构之研究，均居核心地位。
