The Voyage of Hanno"Sailing rapidly, we passed by a fiery region filled with vapors, from which great torrents of fire flowed down to the sea. The land could not be approached because of the heat.
Livio Catulo Stecchini
"We sailed away from there quickly, being struck with fear. Then, having sailed for four days, we sighted at night a land full of flames. And in the midst of it there was a fire higher than the rest which seemed to touch the stars. By day we discerned it to be a mountain of great height named Theon Ochema."
In describing a volcanic eruption from a high mountain towering over the sea Hanno mentions such details as sulphuric fumes and streams of lava. The only volcanic area in West Africa is represented by Mount Cameroon, which is still active today. It is located at the deepest point of the Gulf of Guinea, where it rises suddenly from the seashore, reaching a height of over 4000 meters. The peak of Mount Cameroon is at 4°13'N, 9°10'E. almost exactly 6° (equal to four days' sailing) east of the Great Island of Lagos. Those who have seen it from the sea consider it one of the most impressive sights in the world. The natives call it Mongana-Loba, "Mountain of the Gods," which well agrees with the Greek Theon Ochema, "Chariot of the Gods," of our text.
Typical shot. But shield volcanoes don't make great photographic subjects (from a distance) anyway. There are a few low-cloud images on the Web - it looks like a big hill.
