John Wallis and the Roof of the Sheldonian Theatre: soue.org.uk/souenews/issue4/wa, via an @aperiodical description of a 3d print of the same structure, aperiodical.com/2019/11/my-adv

It's an elegant way to build a wide roof out of short beams with no joinery. But the history is somewhat lacking: Similar structures were known much earlier to Leonardo Da Vinci, Villard de Honnecourt, and Sebastiano Serlio.
