This collective work presents the preliminary results of excavations undertaken by the Canadian archaeological mission to Tell ?Acharneh, Syria in 1998, 1999, and 2002, as well as the results of a study season of excavated materials carried out in the Hama Museum in 2004. Field reports on each annual campaign, prepared by the director of the mission, describe the architectural remains according to their chronological and stratigraphic position at the site. Those reports are completed with specialized studies, written by different experts, of various categories of artifacts recovered over the course of excavations, such as pottery, coins and chipped stone artifacts. The archaeological studies are preceded by articles pertaining to epigraphic sources which make reference to Tunip, a city which is frequently documented in ancient texts and which corresponds most probably to the site of Tell ?Acharneh. Historical documents of the Middle Ages, during which time Tell ?Acharneh became designated by the toponym Tal Ibn Macher, are also discussed in this volume. Cet ouvrage collectif presente les resultats preliminaires des campagnes de fouilles qui ont ete menees par la mission archeologique canadienne en Syrie sur le site de Tell ?Acharneh en 1998, 2001 et 2002, ainsi que de la saison d?etude du materiel archeologique, issu de ces fouilles, qui eut lieu en 2004 au Musee de Hama. Les rapports de fouilles sur les campagnes annuelles, prepares par le directeur de la mission, decrivent les decouvertes architecturales en regard de la chrono-stratigraphie du site. Ces rapports sont completes par des etudes specialisees, realisees par differents experts, portant sur certaines categories d?artefacts recueillies au cours de ces fouilles: ceramique, pieces de monnaie et fragments d?artefacts en pierre taillee. Puisque Tell ?Acharneh pourrait bien correspondre a la ville antique de Tunip mentionnee dans plusieurs textes anciens, les etudes archeologiques sont precedees d?articles traitant de documents epigraphiques, deja connus, relatifs a cette ville. Au Moyen Age, Tell ?Acharneh aurait ete designe par le toponyme de Tal Ibn Macher d?apres la lecture de certaines chroniques de l?epoque qui sont ici commentees.
