If a parr scale is the same as a transversal scale, Tycho Brahe did although I rather suspect it should be spelled with one ‘r’, short for ‘part’.  He was able to do it because his instruments were massive.  2m is quoted for the radius of his quadrant.  I visited the island of Ven in Ore Sound where Brahe had his observatory in TIKI https://sabre27.org.uk/index.php/yacht/tiki/  around 2004.  It’s a lovely island.  It must get very busy if the number of hire bikes set out is anything to go by, 55.90342 12.71849.  I was there out of season, so the place was almost deserted.  You can just walk into the Brahe Museum, 55.90817 12.69544; it’s left unattended as are the remains of the observatory.  His original mounts are very ‘Flintstones’.  I bought a copy of the book showing all his gear, but I gave it away a few years ago to a chap who was a lot more interested in Brahe’s sextants than me.  DaveP
