This is consistent with climate interpretations based on contemporaneous paleo-floral assemblages and geological evidence. None of this is substantiated by contemporaneous documentation. With no dated evidence of rival or contemporaneous kings though, it remains conjecture. References to contemporaneous conditions and historical events also occur.
