The existence of a fire event at the Iron Age hillfort of Nabás, which is located on the southern bank of the Ría de Vigo (Galicia, NW of the Iberian Peninsula), favoured an extraordinary preservation of carbonised plant remains and offered an unusual opportunity to focus our research on the study of the final episode of a house life-cycle. The archaeobotanical approach focused on perishable materials combining charcoal, with carpology and pollen analysis, in tandem with a taphonomic assessment. The charcoal assemblage includes charcoal without signs of working, and wooden manufactures although the former group was probably related to the roof and timber of the round-house. This interpretation is based on the size and concentration of charcoal fragments, as well as the short taxonomic list (deciduous and evergreen Quercus sp., Fabaceae, Corylus avellana, Rosaceae/Maloideae, Salix/Populus, Alnus sp., Frangula alnus, Betula sp., Phragmites/Arundo and Ulmus sp.), and the recurrence of biological alterations such as xylophages' galleries and hyphae. Aggregated grains and chaff of foxtail millet (Setaria italica) were found in several samples suggesting their storage, probably inside an organic container. Finally, pollen analysis offered clues about the uses of plants such as Ericaceae during the occupation phase of the round-house. [ABSTRACT FROM AUTHOR]

The aim of this paper is to reflect on the role of firewood in Roman burial rites of cremation. The case study of Reza Vella (Ourense, Spain) provides valuable information about the uses and the role of plants in a funerary context in northwest Iberia. Archaeobotanical data from Roman cemeteries in this area are very scarce, but they provide valuable information on the funerary customs introduced by the Roman Empire to the provinces, and how this interaction could be reflected in the management of firewood. The structures related to cremation rites include primary and secondary contexts. Charcoal remains recovered inside the structures, of bustum type, are the remains of the fuel burned during the cremation of the corpses. In these primary contexts, the ubiquitous taxa were Quercus sp. deciduous, Fraxinus sp. and Pinus spp. Other taxa, such as Salix/Populus, Prunus sp. and Arbutus unedo, have also been identified in secondary burials. A combination of different factors probably determined their selection for cremation purposes, such as their availability in the environs of the necropolis, differential access to wood resources, their heat potential, technical aspects related to their exploitation and even conceptual aspects, such as their symbolic meaning.
