Did Alexander come to a Styx-y end?

A new speculation about the death of Alexander the Great suggests that the notoriously toxic waters of the River Styx (the modern river Mavroneri) may have taken his life.

Research which will be presented next week at the XII International Congress of Toxicology annual meetings in Barcelona, Spain, "reviews ancient literary evidence on the Styx poison in light of modern geology and toxicology."

According to the study, the waters may have been poisoned by calicheamicin, a byproduct of the bacterium Micromonospora echinospora. Poisoning by calicheamicim could produce the symptoms of Alexander's final illness, including fever, inability to speak, and coma.
