Rumor has it that HP started the project for Lucent *before* the Z3801 came

Technically I agree that they have a lot in common. But I think the large
devices, which are often not cylindrical, are usually called light pipes.

We were talking about remotely viewing light from small things
like LED's. I hardly think that telling me about a 1m diameter
solar light pipe, or the marvels of ancient Egyptians is relevant.
I see two types of devices used for moving light remotely:
