But, though Alexander was thus willing to impress his ignorant soldiers with a mysterious veneration for his fictitious divinity, he was not deceived himself on the subject; he sometimes even made his pretensions to the divine character a subject of joke. For instance, they one day brought him in too little fire in the _focus_. The focus, or fire-place used in Alexander's day was a small metallic stand, on which the fire was built. It was placed wherever convenient in the tent, and the smoke escaped above. They had put upon the focus too little fuel one day when they brought it in. Alexander asked the officer to let him have either some wood or some frankincense; they might consider him, he said, as a god or as a man, whichever they pleased, but he wished to be treated either like one or the other.
