I originally put this question on Mythology SE, but was suggested I move it here.
I was doing some mindless research and came across a Wikipedia page on lost works and went down to the classical period. Nothing grabbed my attention until I saw On Sphere-Making by Archimedes. The title was in red, so I clicked on it and got a blank page.
This tells me that we know nothing that was in the sphere making manuscript. Do we really know nothing? Has nothing survived? If something did survive, what do we know about what Archimedes wrote?
