The idea for the exhibition was conceived after archaeologists found an ornamental oar. So far, it is the only such object, made more than 5 000 years ago, found in Sventoji, a former lake in the middle of the lake where fishing was intensive. Here, rubbish was poured in from settlements on the shores, including animal bones, shards of ceramic vessels and various disused utensils. Over time, this was covered with silt on the bottom of the lake, and the waterlogged environment has allowed it to survive to the present day. Other paddles from the same period have been found in Sventoji, but this one is surprisingly delicately decorated. The blade of the paddle, carved from maple, is decorated with an ornament consisting of herringbone incisions on one side and smaller herringbone and X-shaped incisions on the other. This unique paddle seems to have been important to Stone Age man, as it was repaired after the shaft broke off by attaching an ash pole to the blade's crown. The exquisite objects on display in the exhibition, made of flint, stone, bone and horn, wood, ceramics and amber, enchant with their perfect forms and harmony. Each object in the showcase is special because the person who created it seems to have sought - consciously or unconsciously - to authorise his work by leaving certain marks and decorative elements.
