I posted this in a more obscure page on this website, but I am really curious if anyone on this forum page knows about this rigging from 16th century Portugese ships visiting Japan? I attach a screenshot from an excellent documentary about Portugese sailors visiting Japan for the first time.

It may be simply a misinterpretation on the part of the artist.
