That Viking sunstone story had me rolling my eyes for years
Read a paper last month from some university in Iceland showing how calcite crystals actually do find the sun through clouds within a few degrees. Still not 100% sold they used them on boats, but it's way more believable than I thought.

But if these crystals actually work, why did the Vikings leave so few of them behind in archaeological sites? You would think at least a few would show up buried with navigation tools or in shipwrecks. Either they were way more valuable than we realize, or maybe they just weren't that common.

Heard a theory that maybe they just reused those crystals for other stuff or they broke down over time.
