There it is-small, unimpressive, laying on the heating in front of my desk. A piece of subfossile wood that was buried under sediments for around 7000 years. Sometimes my eyes rest on this piece of wood. I imagine how prehistoric men might have relaxed in the shadow of this tree and behind my small window a forest grows. Reading the tales tree-rings can tell is what makes my job so fascinating. And don´t look the tree-rings and cracks in the scans like lakes and dunes in a mystic landscape?
