well, before Pythagoras came along with the study of the triangle, no one prior to him really unraveled the triangle - or they would have taken Pythagoras' place in the library of history... like some Eureka moment - obviously the triangle was probably used in architecture and what not, but... i doubt the shape of utility in architectural works could have predated the delta letter... Δ... considering the fact that delta is not a right-angle triangle... /\ but an equilateral... yet philosophers like Thales, Anaximander# or Anaximanes would have had to used the letter D to convey their ideas... ah ****... but was the Greek language crafted in isolation from the Egyptians - but weren't the Egyptians not thinking of triangles, but more about stacking a square base? ****... it is... but my library is evidently too poor to say how the letter was derived - whether in isolation or from influence borrowed from the Egyptians... which... bums me out... given D... two Mediterranean cultures would have interacted... whatever... after watching paul joseph watson's video: transgender man identifies as a dog... so they misdiagnosed me as psychotic, paranoid schizophrenic, depressed.... almost 10 year ago.... and now... this? ****... it figures... i guess you can be deemed mad one year, and a year later, after seeing this sort of **** - be deemed completely sane... p.s. in england only the uncomfortable people are given such a diagnosis... or an array of them... uncomfortable people... just like in the Count Monte Cristo... everyone is innocent in Château d'If - as said by Armand Dorleac... 'they don't sent the guilty to Château d'If - they send the ones they're ashamed of.' yep... mad one year, sane another.
