The article presents an edition of and commentary on a Latin bronze inscription (152 lines long) from the time of Hadrian, found at Agón, near Caesaraugusta (Zaragoza), in ancient Hispania Citerior. The inscription contains a set of regulations (lex riui Hiberiensis) governing an irrigation community consisting of rural districts (pagi) from two different cities (Caesaraugusta and Cascantum) which shared a canal, the riuus Hiberiensis. The lex was produced in accordance with an agreement of the pagani after the intervention of the provincial governor [—Fun]ndanus Augustanus Alpinus. It provides information about the pagus institutions (magistri pagi, concilium, curatores, publicani?) as well as procedural aspects such as iusiurandum, uadimonium, and judicial formulae.
