Nearly 40 years ago, Emile Thellier published an article summarizing the archeomagnetic data he had obtained during his career, which had allowed him to recover the main features of the directional variations of the geomagnetic field in France for the last two millennia. This database went on to be significantly completed 25 years ago by Ileana Bucur, who had taken over Thellier's work on archeomagnetism; this forms the current basis of our knowledge of the directional evolution of the geomagnetic field in France. Since then, archeomagnetic studies have been continued at Thellier's historical laboratory in Saint Maur. This article presents the directional archeomagnetic data obtained in France over the past 25 years in this same laboratory. A total of 528 new data are presented, which, together with the 170 results obtained on the French territory previously listed in Bucur (1994), constitute the French directional database (698 data in all). All but two of these data were obtained using the experimental protocol developed by E. Thellier based on the analysis of large samples and on a magnetic viscosity test that has proved its reliability on numerous occasions. The directions from the entire French database have been precisely defined, with 95% of the α 95 values being less than 1.9°, and ~50% being less than 0.8°. The selection of 286 data with dating

La fouille d’une partie d’un four de production céramique ainsi que la datation archéomagnétique de la sole de son alandier ont été réalisées lors d’une opération de diagnostic sur l’ancien hameau d’Agnicourt, aujourd’hui inclus dans la commune de Méru (Oise). Cette intervention a permis d’appréhender la technique de mise en oeuvre de cette structure de combustion ainsi que d’entrevoir la nature de la production. Cette dernière est essentiellement constituée de oules à col en bandeau et de cruches à anses plates réalisées dans une pâte fine sableuse claire portant fréquemment un décor peint. Ce mobilier est caractéristique des récipients en circulation dans le sud de la Picardie et la région francilienne, à l’extrême fin du XIe siècle ou dans la première moitié du XIIe siècle.
