], contacts Linnaeus to get further informed on a botanical fact published in a dissertation published under Linnaeus’s professorship. Since Bailly had found that ancient astronomy was far more advanced than that of later ages, he was eager to find traces of a very ancient tribe with a very advanced culture. He had found that a probable region for that population was Siberia.
