内容简介
塞内加的《自然问题》，约作于公元六三年：他试图不借助诸神来解释天上与地上的种种现象。
背景与流传
书中论流星、闪电、河流、泉源、冰雹、洪水、地震与彗星。其价值不在结论——错的不少——而在意图与方法：塞内加主张，一种可怖的现象，一旦知其原因便不再可怖；研究自然，正是斯多亚学派医治恐惧的疗法之一。因此那些打断论述的道德旁白，其实才是目的所在。论彗星的一卷最为可观：他逆整个古代的公论而立言，说彗星是天体，各有自己的轨道，且终有一日人们会知道它们所循的规律。此英译本（克拉克与盖基译）的书名出自译者，不是塞内加的。
这是编辑性背景，不是可引用的来源：与作品本身的段落不同，这些说明无法在语料库中核对。
XIII. There may be two mock suns simultaneously. Some think the one is a reflection of the other, the clouds acting as mirrors set opposite to one another. Mock suns, especially in the South, are a sign of rain 36 XIV. Other celestial fires. “_Cave meteors_,” “_Barrel meteors_,” “_Chasms_,” with a brief description of each. The rapidity of their flight, just as of lightning, deceives the sight. Their origin and cause. They indicate wind 37 XV. _Gleams_ (_flashes_, σέλα). Their production and motions, varieties of them. Some do damage. Some are analogous to comets. “_Bearded_,” “_torches_,” “_cypress_” are different kinds. “_Beams_” and “_barrels_” may be of the same class. A curious case where such an appearance raised an alarm of fire. They are real fires. On the contrary, rainbows and halos are mere reflections. Mirrors have this wonderful power of false presentation 39 XVI. The “mirrored den” of Hostius Quadra 41 XVII. The philosophy of the looking-glass. The evolution of mirrors. Mirrors of full length are now used. They cost a fortune greater than the Senate gave Scipio’s daughters. A harmless necessary device has become an instrument of luxury, the adornment of women, the burden of men, nay, part of the kit of the soldier 44 BOOK II [THE NATURE OF AIR.
