Take home messages

Tree-ring analysis essential in archaeological research on ship remains. Not only a ‘nice’ dating technique.

Timber conversion

Repairs have high information content.

Symmetrical layout (of bottom) on other cog finds?

Deviating date of keelplank from other cog finds?

Conclusion

‘Belgium is a microcosm of Western Europe (…). The Scheldt and Meuse basins have not only served as the cockpits of Europe: they were also the place where ideas were traded between the Latin and German world (…), it was their ports which for centuries were the entrepôt for merchandise from both North and South’.

Henri Pirenne, Histoire de Belgique, 1900s
