Extractions: Photo courtesy of Innovative Stone For thousands of years, porphyry has been renowned as a beautiful and durable paving and facing stone. A type of volcanic rock consisting of large-grained crystals such as feldspar or quartz, which is formed by a slow cooling process of igneous materials, the stone is valued for its aesthetically pleasing appearance. The term "porphyry" itself refers to the purplish red hues of the stone; in Latin, porphyry means purple. More Info Quarry Locations: North America: Mexico South America: Peru, Argentina Europe: Italy, Sweden Africa: Egypt Asia: Iran Australia Applications: Appropriate Finishes: Porphyry's chemical and mineral composition determine its high compression breaking point, resistance to chemical agents, and low "wearability." The stone is the most popular paver in Europe, and is favored for its flexibility in design, beauty, durability and low maintenance requirements. The stone is by far one of the most durable pavers in the world. In fact, porphyry has been used internationally to create popular projects, such as the Olympic stadium in Munich, Rodeo Drive in Los Angeles, the underground and market square in Paris, John F. Kennedy International Airport in New York and the military cemetery in Hawaii. While porphyry has become a popular paver today, it was originally used for sarcophaguses, busts, vases and columns. The stone that was extracted in the Egyptian desert in the mountain Jebel Dhokan is known as Imperial Red porphyry or Ancient Red porphyry.

Extractions: Installation Porphyry is a type of volcanic, igneous rock which, along with granite and other rock formations, make up approximately 95% of the world's crust. One of many large formations occurs in Guanajuato, Mexico and is recognized for its beautiful rusty red and gold-buff colors. These rocks, which differ greatly in their chemical composition and formation, are the result of intense volcanic activity. This began 260 million years ago and carried over for several million more years, alternating between phases of eruption and inactivity. Porphyry is different than granite, which cooled from its molten state into mainly solid formations, in that as it cooled, it fractured in both vertical and horizontal fissures.

Extractions: Reviewed by John Dillon, Trinity College, Dublin. This is the second in a sequence of translations of surviving Neoplatonic commentaries on the Categories in the Ancient Commentators on Aristotle series edited by Richard Sorabji (the first, though later chronologically, being that of Dexippus, by the present reviewer). Indeed Strange, who is an acknowledged expert on the subject of later interpretations of the Categories , was of considerable help to me, who am really not, in the preparation of my edition, so it is a pleasure for me to welcome his excellent edition now. Like that of Dexippus, Porphyry's short question-and-answer, or 'catechism' commentary is incomplete, breaking off in the middle of a discussion of the contents of ch. 9, though we have indications that Porphyry went on to discuss the Postpraedicamenta too. Basically, however, Porphyry covers the whole of Aristotle's account of the categories proper, whereas the surviving part of Dexippus' commentary only goes as far as the middle of discussion of Quantity (4b23). Porphyry's is somewhat more summary than that of Dexippus, but we must remember that Porphyry already had under his belt that monument of erudition, his big commentary To Gedalius , which is lost, but which we can see from Simplicius formed the basis for all later Neoplatonist commentary on the Categories.

Extractions: Born: 233 in Tyre (now Sur, Lebanon) Died: 309 in Rome Translated by Edwin Hamilton Gifford This collection of fragments is drawn from the lost work of the Neoplatonic philosopher Porphyry On Images. Essentially, the work is a theological and philosophical interpretation of the symbolism of the Greek gods and goddesses. Porphyry explains why the gods and goddesses were represented in certain ways, and how their names and symbolism are allegorical references to the powers of nature or cosmic principles. Porphyry's work is a representative sample of the allegorical approach that was followed by many philosophers and writers in antiquity, including the Stoics, Plutarch, Philo of Alexandria, and the Neoplatonists. First a biography by J J O'Connor and E F Robertson: As a young man Porphyry tried to gain as broad a knowledge as he possibly could by studying many languages and religions. At that time Athens was the main centre for learning, so it was natural that someone with a thirst for knowledge as Porphyry had should travel there to continue his studies. In Athens Porphyry became a student of Longinus who [8]:-

Porphyry is a natural volcanic rock that is quarried internationally and has a long tradition of use throughout Europe, going back to the Roman Empire. A favored choice of material for their famous roads, Porphyry can still be seen on roads & plazas in the Alps, Rome, Milan, Paris and many of the worlds oldest cities. Now it is available to you from Italian owned Mexican quarries, worked according to Italian "Old World" tradition. Both functional and decorative, porphyry suits a variety of different environments. It is specified by architects and town-planners for cottages and country houses, modern and refined homes, or for public and hospitality projects. Porphyry's technical advantages remain unequalled, and it has become one of the world's most sought-after materials. Click on the following:

Thus, just as a species is defined in terms of its genus and a differentia that marks it off from other species of that genus, each genus is defined in terms of its super-genus and a differentia that marks it off from other coordinate genera falling under that super-genus. In a fully explicit definition, each definable term ( definiendum ) is replaced by its definiens . Thus, the fully explicit definition of human will be: This is obtained from the compressed definition above by successively replacing each definable term ( definiendum ) in the definition with its definiens df definiens df definiendum df definiens Metaph.

http://www.wisegeek.com/what-is-porphyry.htm

Extractions: ad_unit_target='mainAdUnit'; X Close this window Porphyry is a Greek term that translates as purple. In the scientific sense it refers to a number of igneous rocks with embedded crystals that give rocks of different types a shiny and glittering appearance. The Romans prized certain types of this rock, especially a brownish feldspar rock with large crystals, made up of plagioclase minerals. Since this color, and anything purple was associated with royalty, you see numerous examples of art and architecture in statue carvings, columns, and various fountains made of brownish feldspar, especially with plagioclase crystals. Not only the Roman Empire, but also the Byzantine Empire made significant use of forms of porphyry in sculpture. Youâll find examples of its use in some very well known places, like the Hagia Sophia Cathedral in Turkey, built during the Byzantine Empireâs Golden Age . Smaller pieces of porphyry might be used in jewelry. Tradition of using these beautiful igneous rocks in sculpture continues today, with many of the large and impressive buildings especially before the 19th century in Europe making use of porphyry in a variety of ways. The rich color and sparkle of the various types of this rock are a treat to the eye when they are used in large amounts in carvings, statues or columns.

http://www.tertullian.org/rpearse/porphyry/hoffmann.htm

Extractions: The 16-book work by the Neoplatonist Porphyry Against the Christians is lost. Constantine ordered that all copies should be destroyed ; a century later Theodosius tacitly acknowledged that this had not occurred by issuing a similar edict in 448 . Although Christians were generally interested in Neoplatonism, and many of Porphyry's major philosophical works still survive , it is hard to see who would have copied a work calculated to offend everyone reading or writing books between 550 and 1450, even without such a edict. Books that insult their readers and copyists have few chances of survival. In 1867, a 15th century manuscript containing an unknown work with the title the Apocriticus of Macarius Magnes was discovered in Epirus and taken to Athens by C. Blondel. The work had been written in 5 books; the Athens MS contained only the portion from the middle of book 2 to the middle of book 4. Blondel made an edition of the text from the MS, which was very corrupt, but died before he was able to publish. The book was published by his friend Foucart in 1876, but without an introduction, and this edition is itself now very rare . This remains the only edition of this work. In 1877 Duchesne examined the manuscript again, and provided a description

Extractions: Animal Rights History Porphyry Why should we not, at the same time, liberate ourselves from many inconveniences by abandoning a fleshly diet ? For we should not be liberated from one only, but from myriads of evils, by accustoming ourselves to be satisfied with things of the smallest nature ; viz. we should be freed from a superabundance of riches, from numerous servants, a multitude of utensils, a somnolent condition, from many and vehement diseases, from medical assistance, incentives to venery, more gross exhalations, an abundance of excrements, the crassitude of the corporeal bond, from the strength which excites to [base] actions, and, in short, from an Iliad of evils. But from all these, inanimate and slender food, and which is easily obtained, will liberate us, and will procure for us peace, by imparting salvation to our reasoning power. For, as Diogenes says, thieves and enemies are not found among those that feed on maize, but sycophants and tyrants are produced from those who feed on flesh. Through these arguments, therefore, and others which we shall afterwards mention, in narrating the opinions of the ancients, it is demonstrated that brutes are rational animals, reason in most of them being indeed imperfect, of which, nevertheless, they are not entirely deprived. Since, however, justice pertains to rational beings, as our opponents say, how is it possible not to admit, that we should also act justly towards brutes ?

Next Porphyry: On the Life of Plotinus and the Arrangement of his Work from Plotinus: The Enneads translated by Stephen MacKenna Typed by Owlsmirror/crows January 2004 1. Plotinus, the philosopher our contemporary, seemed ashamed of being in the body. So deeply rooted was this feeling that he could never be induced to tell of his ancestry, his parentage, or his birthplace. He showed, too, an unconquerable reluctance to sit to a painter of a sculptor, and when Amelius persisted in urging him to allow of a portrait being made he asked him, 'Is it not enough to carry about this image in which nature has enclosed us? Do you really think I must also consent to leave, as a desired spectacle to posterity, an image of the image?' In view of this determined refusal Amelius brought his friend Carterius, the best artist of the day, to the Conferences, which were open to every comer, and saw to it that by long observation of the philosopher he caught his most striking personal traits. From the impressions thus stored in mind the artist drew a first sketch; Amelius made various suggestions towards bringing our the resemblance, and in this way, without the knowledge of Plotinus, the genius of Carterius gave us a lifelike portrait. 2. Plotinus was often distressed by an intestinal complaint, but declined clysters, pronouncing the use of such remedies unbecoming in an elderly man: in the same way he refused such medicaments as contain any substance taken from wild beasts or reptiles: all the more, he remarked, since he could not approve of eating the flesh of animals reared for the table.
