This is a website about Vikings, especially the Norse from Greenland and their exploring of Vinland.
The vikings had a high-developed knowledge about issues as astronomy and navigation, and some sort of knowledge of cartography (portolans), demonstrated through the instruments they used.
From Vebaeks finds in Eastern Settlement in Greenland 1948 - and with help from the computer - we can investigate some of their tools and make experiments and analyses ourselves. Click the images for more information of the bearing dial, the sunstone and the sunstick.
These finds (items) will be extended in both numbers and analyses. Index for special questions (FAQ) on this website: Look for updates here.
From the Sagas we know that the Norse knew how to measure latitudes. We also know that the Norse knew the seasons of the year and some sort of declination so they were able to build a calendar and manage daymarks. Calendar stones were used for organizing the society and planning periodes of sailing.
The Norse used a bearing dial for measuring sunpositions (azimuth) and heights (altitude) around sunrise and sunset, noon and other daymarks (e.g. eykts) for exploring purposes. (Ref.: Leifs expression from Vinland where he talked about "eyktarstadr" (sunset) at "skamdagr" (winter solstice): Find a computersimulation here.
We know from Trelleborg (980 AD) compared with the Bearing-dial that the geometry used are based on the same methods.
