Naturalis Historia

"My subject is a barren one – the world of nature, or in other words life; and that subject in its least elevated department, and employing either rustic terms or foreign, nay barbarian words that actually have to be introduced with an apology. Moreover, the path is not a beaten highway of authorship, nor one in which the mind is eager to range: there is not one of us who has made the same venture, nor yet one Roman who has tackled single-handed all departments of the subject."
Naturalis Historia was written by Pliny the Elder between 77 and 79 CE and was meant to serve as a kind of proto-encyclopedia discussing all of the ancient knowledge available to him, covered in enough depth and breadth to make it by a reasonable margin the largest work to survive to the modern day from the Roman era. The work includes discussions on astronomy, meteorology, geography, mineralogy, zoology and botany organized along Aristotelian divisions of nature but also includes essays on human inventions and institutions. It is dedicated to the Emperor Titus in its epistle to the Emperor Vespasian, a close friend of Pliny who relied on his extensive knowledge, and its unusually careful citations of sources as well as its index makes it a precursor to modern scholarly works. It was Pliny's last work, as well as sadly his sole surviving one, and was published not long before his death attempting to save a friend from the eruption of Mt. Vesuvius that destroyed Pompeii and Herculaneum, famously recounted by Pliny's eponymous nephew Pliny the Younger.
Here is a reasonable translation that is freely available to download from archive.org for your edification.

Get out the indestructable tin foil hat

Introducing: Metal Rubber. "Twist it, stretch it double, fry it to 200°C, douse it with jet fuel—the stuff survives. After the torment, it snaps like rubber back to its original shape, all the while conducting electricity like solid metal." Sounds familiar, no? Here's the son of the Roswell air field's intel officer, describing the debris he says he saw in 1947: "It was possible to flex this stuff back and forth, even to wrinkle it, but you could not put a crease in it that would stay, nor could you dent it at all. I would almost have to describe it as a metal with plastic properties." The UFO freaks are already all over the "back engineering" of Roswell crash debris. Meanwhile, there's something unusual in the sky over Minnesota right now.
