This study gives importance to the differences, in the field of funerary, between the autochthon world, specially represented by two necropolis, Enserune and Ambrussum, and the Greek colonies, particularly known by cemeteries of Sainte-Barbe in Marseille/Massalia and of the Peyrou II in Agde/Agathe : treatment of perinatals, present in the native settlements and absent in their necropolis, but normally attested in the necropolis of Marseille/Sainte-Barbe ; almost exclusive incineration for the dead of the native world, except the south Alps and instance of perinatals inhumed in the settlements ; defuncts incinerated and inhumed mixed in Marseille and Agde, but children out of ten years always inhumed in Marseille ; in the two cultural spheres, different stakes and depots of incinerated bones either in an ossuary , or directly in the loculus ; shared tombs, adult and child, well attested in the native world, exceptional in Marseille ; the form of the tomb varies according to the treatment of the corpse, the use or not of an ossuary vase, the depot of accompaniment articles. Most of the funeral practices of this native world already existed in the First Iron Age and The Late Bronze IIIb ; the changes of the Second Iron Age especially lie in the relative frequencies of these different uses and a standardization inclining to exclude the dichotomy between Western Languedoc on one hand and Eastern Languedoc and Provence on the other hand.
