Natural History (Pliny) in the context of "Bylliones"

Gaius Plinius Secundus (23 or 24 CE - 25 August 79 CE), known in English as Pliny the Elder (/ˈplɪni/ PLIN-ee), was a Roman author, naturalist, scientist, naval and army commander of the early Roman Empire, and friend of the emperor Vespasian. Pliny wrote the encyclopedic Naturalis Historia (Natural History), a comprehensive thirty-seven-volume work covering a vast array of topics on human knowledge and the natural world, which became an editorial model for encyclopedias. He spent most of his spare time studying, writing, and investigating natural and geographic phenomena in the field.

Among Pliny's greatest works was the twenty-volume Bella Germaniae ("Wars of Germania"), which is no longer extant. Bella Germaniae, which began where Aufidius Bassus' writings on Germani wars left off, was used as a source by other prominent Roman historians, including Plutarch, Tacitus, and Suetonius. Tacitus may have used Bella Germaniae as the primary source for his work, De origine et situ Germanorum ("On the Origin and Situation of the Germani").

De agri cultura ([deː ˈaɡriː kʊlˈtuːraː]), also known as On Farming or On Agriculture, is a treatise on Roman agriculture by Cato the Elder. It is the oldest surviving work of Latin prose. Cato was revered by many later authors for his practical attitudes, his natural stoicism and his tight, lucid prose. He is much quoted by Pliny the Elder, for example, in his Naturalis Historia.

Regio VI Umbria (also named Regio VI Umbria et Ager Gallicus) is the name for one of the 11 administrative regions into which the emperor Augustus divided Italy. The main source for the regions is the Historia Naturalis of Pliny the Elder, who informs his readers he is basing the geography of Italy on the descriptio Italiae, "division of Italy", made by Augustus. The Regio Sexta ("6th Region") is called Umbria complexa agrumque Gallicam citra Ariminium ("Umbria including the Gallic country this side of Rimini").

Umbria is named after an Italic people, the Umbri, who were gradually subjugated by the Romans in the 4th through the 2nd centuries BC. Although it passed the name on to the modern region of Umbria, the two coincide only partially. Roman Umbria extended from Narni in the South, northeastward to the neighborhood of Ravenna on the Adriatic coast, thus including a large part of central Italy that now belongs to the Marche; at the same time, it excluded the Sabine country (generally speaking, the area around modern Norcia) and the right bank of the Tiber, which – being inhabited by Etruscans – formed part of Regio VII Etruria: for example Perusia (the modern Perugia) and Orvieto (its ancient name is unknown), two Etruscan cities – were not part of Roman Umbria; on the contrary Sarsina, Plautus birthplace, was considered to be "in Umbria", while today it is in the modern province of Forlì-Cesena, in Emilia-Romagna.

Etymologiae (Latin for 'Etymologies'), also known as the Origines ('Origins'), usually abbreviated Orig., is an etymological encyclopedia compiled by the influential Christian bishop Isidore of Seville (c. 560–636) towards the end of his life. Isidore was encouraged to write the book by his friend Braulio, Bishop of Saragossa. Etymologiae summarized and organized a wealth of knowledge from hundreds of classical sources; three of its books are derived largely from Pliny the Elder's Natural History. Isidore acknowledges Pliny, but not his other principal sources, namely Cassiodorus, Servius, and Gaius Julius Solinus.

Etymologiae covers an encyclopedic range of topics. Etymology, the origins of words, is prominent, but the work also covers, among other things, grammar, rhetoric, mathematics, geometry, music, astronomy, medicine, law, the church and heretical sects, pagan philosophers, languages, cities, humans, animals, the physical world, geography, public buildings, roads, metals, rocks, agriculture, war, ships, clothes, food, and tools.

Silanion (Ancient Greek: Σιλανίων, gen. Σιλανίωνος) was the best-known of the Greek portrait-sculptors working during the fourth century BC. Pliny gives his floruit as the 113th Olympiad, that is, around 328–325 BCE (Natural History, 34.51), and records he had no famous teacher. His idealized portrait head of Plato was commissioned by Mithridates of Persia for the Academy of Athens, c. 370 BC. Later copies of it and of an idealized portrait head of Sappho survive. Both are of simple ideal type, the Sappho not strictly a portrait, since Sappho (sixth century BC) lived before the age of portraiture. The best copy of Plato is in the Glyptothek of Munich (illustration).

Silanion also produced a "portrait" of the poet Corinna. Other "portrait" heads by Silanion evoked mythic and legendary heroes. An Achilles mentioned by Pliny was later adapted to represent Ares, and an equally idealized Theseus is mentioned by Plutarch.

Chares of Lindos (/ˈkɛəriːz/; Ancient Greek: Χάρης ὁ Λίνδιος, gen.: Χάρητος; before 305 BC – c.280 BC) was a Greek sculptor born on the island of Rhodes. He was a pupil of Lysippos. Chares constructed the Colossus of Rhodes in 282 BC, an enormous bronze statue of the sun god Helios and the patron god of Rhodes. The statue was built to commemorate Rhodes' victory over the invading Macedonians in 305 BC, led by Demetrius I, son of Antigonus, a general under Alexander the Great.Also attributed to Chares was a colossal head that was brought to Rome and dedicated by P. Lentulus Spinther on the Capitoline Hill in 57 BC (Pliny, Natural History XXXIV.18).

The Colossus of Rhodes is one of the Seven Wonders of the Ancient World, and was considered Chares's greatest accomplishment, until its destruction in an earthquake in 226 BC.

In European bestiaries and legends, a basilisk (/ˈbæsɪlɪsk/ or /ˈbæzɪlɪsk/) is a legendary reptile reputed to be a serpent king, who causes death to those who look into its eyes. According to the Naturalis Historia of Pliny the Elder, the basilisk of Cyrene is a small snake, "being not more than twelve inches in length", that is so venomous, it leaves a wide trail of deadly venom in its path, and its gaze is likewise lethal.

According to Pliny, the basilisk's weakness is the odor of a weasel. The weasel was thrown into the basilisk's hole, recognizable because some of the surrounding shrubs and grass had been scorched by its presence. It is possible that the legend of the basilisk and its association with the weasel in Europe was inspired by accounts of certain species of Asiatic and African snakes (such as cobras) and their natural predator, the mongoose.
