Recent advances in semantic web and deep learning technologies enable new means for the computational analysis of vast amounts of information from the field of digital humanities. We discuss how some of the techniques can be used to identify historical and cultural symmetries between different characters, locations, events or venues, and how these can be harnessed to develop new strategies to promote intercultural and cross-border aspects that support the teaching and learning of history and heritage. The strategies have been put to the test in the context of the European project CrossCult, revealing enormous potential to encourage curiosity to discover new information and increase retention of learned information.

Sustainability in Cultural Heritage (CH) is a complex question that needs to be addressed by a group of experts tackling the different issues. In this light, the present work wishes to provide a multi-level analysis of the sustainability in CH, using as an example a recent European H2020 project (CrossCult) and the lessons learnt from its design, implementation and evaluation. The sustainability of CH has qualitatively changed over the last few years, under the developments in digital technology that seems to affect the very nature of the cultural experience. We discuss sustainability in venues using digital technologies, covering a span of needs of small/unknown and large/popular venues, which try to enhance the visitor experience, attract visitors, form venue networks, etc. Moreover, we explore issues of sustainability of digital content and its re usability through holistic design. Aspects of technology, human networks and data sustainability are also presented, and we conclude with the arguments concerning the sustainability of visitor reflection, the interpretation of social and historical phenomena and the creation of meaning.

The North Western Iberia metal ore wealth, especially tin ore and gold, have been proposed as the main reason for the development of intense trade routes since early prehistory. Several authors have argued the existence of interactions between the northwest of the Iberian Peninsula and other cultures of the European Occident and the Mediterranean area. Ancient sources comment on the abundance of minerals and metals in the Cassiterides or Tin Islands. These accounts must have originated from sailors who from time immemorial were trading in these coasts. The name Cassiterides represents the first vague knowledge of the Greeks that tin was found overseas somewhere in or off Western Europe. The word κασσιτερος was known to Homer and is mentioned ten times in the Iliad. Cape Finisterre (Land's End for the Romans) was proposed as the northernmost point recorded in the Periplous of Pytheas the Massaliot, which seems to be the basic source used by Rufus Festus Avienus. B.Cunliffe has suggested that if Cape Finisterre was the place called Oestrymnis by Avienus in Ora Marítima, then Periplous could be seen as the guide that led Greek sailors from Marseille to the northwest of Iberia to trade for the coveted Galician tin some time around 500 BC.Recently, the study of prehistoric bronze working places more emphasis on technological aspects as a means of detecting changes in the pattern of metal production in the archaeological record. Bronze working appears in North Western Iberia at the end of the 3rd and the beginning of the 2nd millennium BC for short-scale production, distribution and consumption, mainly as prestige goods. Metals are a major component of the prestige economy described in the Homeric Epics and his accounts of Phoenician traders carrying metals hither and thither constitute the earliest literature reference. They suggest a prestige economy based in interchange of presents (most of them metals) that contribute to the perpetuation of the aristocracy, excluding ownership by the rest of the population.Recent preliminary analyses carried out at the synchrotron and the neutron sources at the Daresbury and Rutherford Laboratories have contributed to the understanding of technological details of this very early bronze metallurgy. Archaeological evidence sustains the hypothesis of an increase of the production during the late Bronze Age. Most of these objects are produced locally, imitating foreign styles, especially in the Atlantic area, with singular features related to the alloy composition and other features. Indeed, as early as the beginning of the 8th century BC, the Phoenicians had established a trading post at Gadir. From here Phoenician ships regularly sailed north up the Atlantic coast of Iberia. We can observe differences between the Late Bronze Age-Iron Age north-western metal production and the so-called tartesic bronzes. στορικου χαλκου δινει µεγαλυτερη εµφα ση σε τεχνολογικες λεπτοµερειες των αρχαιολογικων ευρηµατων για την ανιχνευση αλ λαγων στη µεταλλουργικη τεχνη.

We present the concept and early design of a crowd computing system that aims at involving people in the annotation of unread cuneiform tablets, in an attempt to (i) increase public awareness about the history of Ancient Mesopotamia and (ii) to supplement the shrinking force of experts in the subject with the contributions of interested individuals, who are instructed in reading from the simplest inscriptions towards more complex ones in a gamified strategy.
