Archaeological excavations in the docking site of Pisa (Central Italy) unearthed several shipwrecks which dated back to the Roman time, from the Republican to the Imperial periods. The recent identification of the woods used for building ships D, E, H, I and P, in addition to data of the previous analysis of ships A, B, C, F, L, revealed the utilization of 18 different taxa . Wood from oaks, both deciduous and evergreen, is mostly represented. 6 different softwood timbers, mostly from maritime and umbrella pine, were also largely used. Some of the hulls were entirely realized with hardwoods, others with softwoods or using a combination of softwoods for planking (mostly pines) and different hardwoods for the frame. The selection of timber indicates a skilful knowledge of the technological properties of the different woods and their suitable utilization in the Roman vessels. The use of woods largely available in the territory surrounding the Pisa docking site, as demonstrated by pollen analysis, does not necessary indicate the local production and/or provenance of the ships, given the spread of the identified wood taxa throughout the North Mediterranean area.

Paper deals with the scientific identification of timbers utilised for the production of the sculptures preserved within the collection of the National Museum of the “Palazzo di Venezia” in Rome, Italy. After a brief description of the Museum and its sculpture collections, and, more specifically, the wooden sculpture collection which is the largest in Italy, the sampling of the artwork is discussed and described, together with the methodology used for the identification of wood species following the Italian standard UNI 11118:2004. The 12 identified timbers are listed together with their distribution within the cultural provenance of the sculptures. The discussion deals with the timber species utilised by the artists from the four cultural European provenances most represented within the collection: Italy, Alps, central-southern Germany and Lowlands around the Rhine delta. In the different Italian regions, several wood species were utilised and among them mostly poplar and limewood, while the alpine sculptors mostly used Swiss stone pine and the German artists, limewood. Finally in the Rhine delta, most of the sculptures were made out of deciduous oak. [ABSTRACT FROM AUTHOR]

Highlights • The wooden foundations of Ponte di Rialto were analysed in order to determine the tree species used for its construction and to examine the timber's present-day physical and mechanical properties. • The foundations underwent micro-morphological, physical, chemical and mechanical analyses. • The footings of the bridge's foundations, mostly consisting of alder wood, were shown to be in a good condition generally. • Two periods of construction were determined. The later dating corresponds to the construction of the stone bridge that still exists today, while the other period probably refers to the foundations of the initial Ponte della Moneta. Abstract The wooden foundations of Ponte di Rialto (Rialto Bridge), the oldest and most famous of the four bridges spanning the Grand Canal in Venice, Italy, were analysed in order to determine the tree species used to construct the foundation, to examine the timber's present-day physical and mechanical properties and to identify construction periods. The material recovered during geotechnical surveys underwent micro-morphological, physical, chemical and mechanical analyses. The radiocarbon method was used for dating purposes. The footings of the bridge's foundations, mostly consisting of alder wood, were shown to be in good overall condition generally. A comparison of normal and polarised light images of wooden cross-sections showed abundant crystalline cellulose within the cell walls, indicating that the state of conservation of the waterlogged samples is very close to that of sound alder wood. Only one alder sample showed signs of severe bacterial attack, mostly concentrated in the fibre cell walls. Radiocarbon dating identified two distinct construction periods. One sample dates to 1570 AD ± 85, whilst another dates to the year 960 AD ± 59. The later dating corresponds to the construction of the stone bridge that still exists today. The earlier period, around the year 1000, likely refers to the foundations of the first bridge, built after several pontoon bridges, and corresponding to the initial Ponte della Moneta.
