The Archaeological Recording Kit (ARK) written by L-P Archaeology has been further updated on site by Henriette and Hembo. This is the centre of all our archaeological data management processes. All data gathered on site are ingested and made available on our on-site wireless network. ARK looks after all our many photographs, the raw data from the geophysics and surveys, processed plans and sections and the database of all finds.
At a site as large and complex as Portus, it is often hard to work out the building phases of individual structures, or get a feel for the original landscape. The AHRC portus Project is therefore employing a range of visualisation tools to interpret and present the site as it is now and as we believe it was in the past. Computer graphics make the site easier to understand by presenting archaeological findings in an easily comprehensible, but historically accurate format.
Polynomial Texture Mapping (PTM) has been employed throughout the AHRC Portus Project. It is a technique that enables the production of detailed surface models of particular artefacts from a series of digital photographs (Malzbender et al 2001; Mudge et al 2005).
E. Ships and Boats Archaeological evidence has greatly enhanced our knowledge of Roman shipping in recent years. There are hundreds of shipwrecks from the Roman period (Parker 1992), which have done much to develop our understanding of hull construction and to illuminate some of the fundamental points of shipbuilding and sailing, such as mast position.
B. Colour Scheme Excavations beneath the Basilica Portuense by the Soprintendenza di Beni Archeologici di Ostia (Dottssa Lidia Paroli) revealed a sequence of buildings going back to the mid 1st century AD. The outer faces of these brick-faced buildings were covered with reddish, orangeish and yellowish plaster. On this basis it has been assumed that, apart from the temple complex, most buildings would have been decorated in one colour or another.
The computer models of Portus produced prior to the start of the AHRC Portus Project were based upon the interpretation of standing structural remains uncovered by successive archaeologists, particularly Lanciani (1868), Lugli (Lugli & Filibeck 1935) and Testaguzza (1970) as well as more recent topographic work undertaken by the Soprintendenza di Beni Archeologici di Ostia, and most the survey work undertaken by the Universities of Southampton and Cambridge in association with the British...
