Oh it wasn't much. Maybe he didn't know or was just exaggerating
  for affect. The "we're all made of stars" thing from ancient
  times was actually from a lecture by a fellow canadian
  astronomer in 1916. Traced it back - couldn't find anything any
  further than that. Inspiratonal - and I suppose in some sense it
  *could* be considered from ancient times if you put together
  various mythologies and read them that way - but from a
  literature pov, he kinda plagurised it, willingly or
  unknowingly. No biggie really but I was a little disappointed.
  Then again, he used it in 1973 with his book and it *kinda* made
  him famous, so he's wasn't about to let that gem go by. It has
  the mystique and the wonder and all that. I like it.
