Episode 089 - Unusual Geological Phenomena - Springs That Change From Hot to Cold And Back Again

Lucretius Today - Epicurus and Epicurean Philosophy - A podcast by Cassius Amicus

Categories:

Welcome to Episode Eighty-Nine of Lucretius Today. I am your host Cassius, and together with my panelists from the EpicureanFriends.com forum, we'll walk you through the six books of Lucretius' poem, and discuss how Epicurean philosophy can apply to you today. We encourage you to study Epicurus for yourself, and we suggest the best place to start is the book, "Epicurus and His Philosophy" by Canadian professor Norman DeWitt. For anyone who is not familiar with our podcast, please visit EpicureanFriends.com where you will find our goals and our ground rules. If you have any questions about those, please be sure to contact us at the forum for more information.In this Episode 89 we will read approximately Latin lines 830-917 as we discuss the hot and cold springs and similar phenomena.Now let's join Martin reading today's text.Browne 1743[830] Or else, sometimes, the force and rising blasts of these Averni dispel the air that lies between the birds and the earth, and the intermediate space becomes a void. Here, when birds are carried by their flight, they immediately flutter in the air, they clap their wings in vain, their pinions flag, and when they can no longer bear them up, nature must drive them down upon the earth with all their weight; and as they, helpless, in the vacuum lie, they breathe their soul abroad through every pore.[840] The water in some wells, we find, is cold in summer, because the earth is rarefied by the sun's heat, and by that means the seeds of fire it contains within break freely out into the Air: And therefore the more the earth is affected by the heat, the colder the water will be that is enclosed within. But when the earth is contracted with the cold, when its surface grows close, and its pores are stopped, this restraint hinders the heat from flying out; it is then squeezed together into the wells, and the water becomes hot.[848] There is a fountain, near the temple of Jupiter Ammon, that is cold in the day, and hot by night. Men strangely wonder at the quality of this spring, and imagine that when the night has spread her dreadful darkness over the world the water is warmed by the violent heat of the sun through the body of earth. But this reason is far from being true; for if the sun, striking upon the open body of water, is not able to warm even the surface of it, when it receives the force of his descending rays with all their heat, how can he warm the water, and infuse his heat through so thick a body as the Earth; especially since he is scarce able, with his scorching beams, to pierce through the walls of our houses?[861] What then is the reason? Doubtless this: because the Earth, near this fountain, is more rare and spongy then it is in other places, and contains within it many seeds of fire near the body of the water itself. Here, when the night has spread the world with dewy shades, the earth below grows initially cold, and is contracted; by this means it is compressed, as with your hand, and squeezes out those seeds of fire into the spring, which make the water warm to feel and taste. But when the sun has driven away the night with his bright rays, and with his heat has rarefied the Earth, and made it loose, these seeds of fire return into their former place, and all the heat that warmed the spring retires within the earth again, and so the fountain in the day is cold.[874] Besides, the water in the day is strongly moved by the sun's rays, and by his trembling streams of heat grows rare, and so lets out the seeds of fire it held by night; just as by the heat it shakes off seeds of cold, and melts the ice, and loosens all its bonds.[879] There is likewise a cold spring over which if you place tow or flax it immediately takes fire and is all in a blaze. A torch, newly extinguished, in the same manner, gently drawn over the surface, is lighted by this water, and flames out at every...
