As exciting as it is to discover ancient artefacts during an excavation, our post-excavation team reveals all sorts of hidden secrets during their analyses. This stone disc (right) was found to have an incised spiral doodle decoration that was not visible until we cleaned it up back in the lab. If you click on the image below, you can open a Reflectance Transformation Imaging (RTI) viewer which allows you to play around with the lighting to enhance the incised decoration, giving you the best possible view. Have a look and see what you think of the incised decoration – is it just a doodle, or does it depict a recognisable form?
Once the viewer has opened, you can use the tools along the left hand side to enhance the image: open the image in full screen, zoom in and out, and with the light bulb button selected, click on the image to alter the direction of the light source. Clicking around the edges of the image, for example, will produce a raking light effect that makes the decoration much easier to make out. Have fun!
