It is not known what species it was, but a scholar has suggested that it was a yew tree. Near that temple is a very large tree with widespread branches which are always green both in winter and summer. What kind of tree it is nobody knows. There is also a spring there where the pagan are accustomed to perform sacrifices and to immerse a human being alive. As long as his body is not found, the request of the people will be fulfilled.
