WHY MUSHROOMS ARE THOUGHT TO BE PRODUCED BY THUNDER, AND WHY IT IS BELIEVED THAT MEN ASLEEP ARE NEVER THUNDERSTRUCK.
AGEMACHUS, PLUTARCH, DOROTHEUS.
At a supper in Elis, Agemachus set before us very large mushrooms.

And when all admired at them, one with a smile said, These are worthy the late thunder, as it were deriding those who imagine mushrooms are produced by thunder.

Some said that thunder did split the earth, using the air as a wedge for that purpose, and that by those chinks those that sought after mushrooms were directed where to find them; and thence it grew a common opinion, that thunder engenders mushrooms, and not only makes them a passage to appear; as if one should imagine that a shower of rain breeds snails, and not rather makes them creep forth and be seen abroad.

Agemachus stood up stiffly for the received opinion, and told us, we should not disbelieve it only because it was strange, for there are a thousand other effects of thunder and lightning and a thousand omens deduced from them, whose causes it is very hard, if not impossible, to discover; for this laughed-at, this proverbial mushroom doth not escape the thunder because it is so little, but because it hath some antipathetical qualities that preserve it from blasting; as likewise a fig-tree, the skin of a sea-calf (as they say), and that of the hyena, with which sailors cover the ends of their sails.

And husbandmen call thunder-showers nourishing, and think them to be so.
Indeed, it is absurd to wonder at these things, when we see the most incredible things imaginable in thunder, as flame rising out of moist vapors, and from soft clouds such astonishing noises.
