hi pericles nice to see you here i surfed a bit through your edits no offense intended but do you think it is appropiate to include chinese material in the life of eratosthenes does that mean we also have to include greek material in an article on zheng hang also i feel legendary material like the supposed invention of a south pointing chariot vears before the actual invention had been done has little place in an encyclopedia or should we now also include icarus in an article on the history of aviation regards
