Waarom we onder water moeten kijken om ons verleden te begrijpen
Overblijfselen uit het verleden liggen voor een groot deel verborgen in rivieren, meren en zeeën. Helaas kijken we zelden onder water, en onbekend maakt onbemind. Martijn Manders vertelt in zijn oratie waarom onderwaterarcheologie zo belangrijk is voor het begrijpen van onze geschiedenis.

Prehistorische bijl uit het water gehaald door Texelse visser
Zes jaar geleden is een stenen bijl uit de prehistorie opgevist door een Texelse visser. De bijl, gevonden in zijn vissersnet, komt vermoedelijk uit de middensteentijd en is waarschijnlijk zo'n 8000 jaar oud. Afgelopen week kwam Astrid van de Wetering, die de steen zag liggen bij de visser, met deze…
