In Book 2, Chapter 26 of Nishmat Hayyim (Amsterdam, 1651), Menasseh ben Israel writes:
The practice of elephants is similar. If one of them kills a human being, he does not leave the body until he has cut branches and twigs from the trees of the forest and covered it up and buried it beneath them.
Does anyone know of possible source from which Menasseh may have derived this idea?
