NavList:

Bill Lionheart has proposed a device which with a little honing might produce an excellent analogue instrument for finding the symmedian point of a triangle.  This has navigational applications in the study of the ‘cocked hat’ produced by the intersection of three position lines.

I’m sorry to come to this post rather late, but I’ve had a busy Christmas, partly reading Seb Falk’s ‘The Light Ages’.  With a head full of medieval instruments such as the Sun dial, nocturnal, astrolabe, torquetum, and equatorium used by 14th-century monks and others, I believe the NavList Community needs to do full justice to Bill’s invention by deciding upon a name for it.  I have my own ideas, but I want to give others a chance to express their opinions.  So NavListers, what are your suggestions for a name for Bill’s invention and why?  DaveP
