Friend of mine sent me this pic he found on the Internet. No idea where it is or what the overall structure is, but check out the joinery.

I'm trying to understand how one would put those together. You can't slide one end into the other, can you?

Absolutely not. They obviously won't slide at all. You have to place alternate beams.

So is the second "hook" tenon (do those qualify as tenons?) purely aesthetic or does it actually serve from a structural perspective? I would assume any added strength or stability would be negligible but it sure looks awesome. I bet that thing could survive another 500 years.

Totally amazing but I bet with a little practice and the proper tools it's not that hard to master. Looks like equal size timbers so templates would work. I'm sure they are nicely fitted but only the part that shows has to be perfect.

I believe they all serve to enhance the structural integrity but the 2nd one is slightly redundant, yes.
