Cimolian Earth
Cimolian Earth (Greek: κιμωλια, Latin: ''terra simolia''), also known as "cimolite", refers to a variety of clays used widely in the ancient world. These clays were used in medicine, in bleaching, and in the washing of clothes. They appear to be similar to Fuller's earth, and to Kaolin. A variety of colours of Cimolian Earth was known. Etymology The name ''Cimolian earth'' was derived from Kimolos, an Aegean island north-east of Melos, also known as Argentiera. History Of the earlier mentionings of cimolian earth, the mishna mentions kimonia -קימוניא- as part of a seven detergent formula used by the Jewish nation for the treatment of clothing tzoraath and niddah stains (tractate niddah, ch. 9). The Stockholm papyrus manuscript, found in 1828 in a tomb in Thebes and dated to 300 BC, describes a washing powder especially for wool. This powder was composed of aqueous soda solution, Cimolian Earth, dispersed in vinegar, slaked lime, fine clay, and caustic potash solutio ...

Ancient World
Ancient history is a time period from the beginning of writing and recorded human history to as far as late antiquity. The span of recorded history is roughly 5,000 years, beginning with the Sumerian cuneiform script. Ancient history covers all continents inhabited by humans in the period 3000 BCAD 500. The three-age system periodizes ancient history into the Stone Age, the Bronze Age, and the Iron Age, with recorded history generally considered to begin with the Bronze Age. The start and end of the three ages varies between world regions. In many regions the Bronze Age is generally considered to begin a few centuries prior to 3000 BC, while the end of the Iron Age varies from the early first millennium BC in some regions to the late first millennium AD in others. During the time period of ancient history, the world population was already exponentially increasing due to the Neolithic Revolution, which was in full progress. While in 10,000 BC, the world population stood ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calcium Hydroxide
Calcium hydroxide (traditionally called slaked lime) is an inorganic compound with the chemical formula Ca( OH)2. It is a colorless crystal or white powder and is produced when quicklime ( calcium oxide) is mixed or slaked with water. It has many names including hydrated lime, caustic lime, builders' lime, slaked lime, cal, and pickling lime. Calcium hydroxide is used in many applications, including food preparation, where it has been identified as E number E526. Limewater, also called milk of lime, is the common name for a saturated solution of calcium hydroxide. Properties Calcium hydroxide is poorly soluble in water, with a retrograde solubility increasing from 0.66 g/L at 100 °C to 1.89 g/L at 0 °C. With a solubility product ''K''sp of 5.02 at 25 °C, its dissociation in water is large enough that its solutions are basic according to the following dissolution reaction: : Ca(OH)2 → Ca2+ + 2 OH− At ambient temperature, calcium hydroxide ( portlandite) ...

Medicinal Clay
The use of medicinal clay in folk medicine goes back to prehistoric times. Indigenous peoples around the world still use clay widely, which is related to geophagy. The first recorded use of medicinal clay goes back to ancient Mesopotamia. A wide variety of clays are used for medicinal purposes—primarily for external applications, such as the clay baths in health spas (mud therapy). Among the clays most commonly used are kaolin and the smectite clays such as bentonite, montmorillonite, and Fuller's earth. History Ancient Egypt and Mesopotamia The first recorded use of medicinal clay is on Mesopotamian clay tablets around 2500 B.C. Also, ancient Egyptians used clay. The Pharaohs’ physicians used the material as anti-inflammatory agents and antiseptics. It was used as a preservative for making mummies and is also reported that Cleopatra used clays to preserve her complexion. The Ebers Papyrus of about 1550 BC (but containing the tradition going back many centuries earlier) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laundry Substances
Laundry refers to the washing of clothing and other textiles, and, more broadly, their drying and ironing as well. Laundry has been part of history since humans began to wear clothes, so the methods by which different cultures have dealt with this universal human need are of interest to several branches of scholarship. Laundry work has traditionally been highly gendered, with the responsibility in most cultures falling to women (formerly known as laundresses or washerwomen). The Industrial Revolution gradually led to mechanized solutions to laundry work, notably the washing machine and later the tumble dryer. Laundry, like cooking and child care, is still done both at home and by commercial establishments outside the home. The word "laundry" may refer to the clothing itself, or to the place where the cleaning happens. An individual home may have a laundry room; a utility room includes but is not restricted to the function of washing clothes. An apartment building or student ha ...

Maimonides
Musa ibn Maimon (1138–1204), commonly known as Maimonides (); la, Moses Maimonides and also referred to by the acronym Rambam ( he, רמב״ם), was a Sephardic Jewish philosopher who became one of the most prolific and influential Torah scholars of the Middle Ages. In his time, he was also a preeminent astronomer and physician, serving as the personal physician of Saladin. Born in Córdoba, Almoravid Empire (present-day Spain), on Passover eve, 1138 (or 1135), he worked as a rabbi, physician and philosopher in Morocco and Egypt. He died in Egypt on 12 December 1204, when his body was taken to the lower Galilee and buried in Tiberias. During his lifetime, most Jews greeted Maimonides' writings on Jewish law and ethics with acclaim and gratitude, even as far away as Iraq and Yemen. Yet, while Maimonides rose to become the revered head of the Jewish community in Egypt, his writings also had vociferous critics, particularly in Spain. Nonetheless, he was posthumously ...

Mishnah
The Mishnah or the Mishna (; he, מִשְׁנָה, "study by repetition", from the verb ''shanah'' , or "to study and review", also "secondary") is the first major written collection of the Jewish oral traditions which is known as the Oral Torah. It is also the first major work of rabbinic literature. The Mishnah was redacted by Judah ha-Nasi probably in Beit Shearim or Sepphoris at the beginning of the 3rd century CE in a time when, according to the Talmud, the persecution of the Jews and the passage of time raised the possibility that the details of the oral traditions of the Pharisees from the Second Temple period (516 BCE – 70 CE) would be forgotten. Most of the Mishnah is written in Mishnaic Hebrew, but some parts are in Aramaic. The Mishnah consists of six orders (', singular ' ), each containing 7–12 tractates (', singular ' ; lit. "web"), 63 in total, and further subdivided into chapters and paragraphs. The word ''Mishnah'' can also indicate a single paragraph ...

Babylonian Talmud
The Talmud (; he, , Talmūḏ) is the central text of Rabbinic Judaism and the primary source of Jewish religious law ('' halakha'') and Jewish theology. Until the advent of modernity, in nearly all Jewish communities, the Talmud was the centerpiece of Jewish cultural life and was foundational to "all Jewish thought and aspirations", serving also as "the guide for the daily life" of Jews. The term ''Talmud'' normally refers to the collection of writings named specifically the Babylonian Talmud (), although there is also an earlier collection known as the Jerusalem Talmud (). It may also traditionally be called (), a Hebrew abbreviation of , or the "six orders" of the Mishnah. The Talmud has two components: the Mishnah (, 200 CE), a written compendium of the Oral Torah; and the Gemara (, 500 CE), an elucidation of the Mishnah and related Tannaitic writings that often ventures onto other subjects and expounds broadly on the Hebrew Bible. The term "Talmud" may refer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sodium Carbonate
Sodium carbonate, , (also known as washing soda, soda ash and soda crystals) is the inorganic compound with the formula Na2CO3 and its various hydrates. All forms are white, odourless, water-soluble salts that yield moderately alkaline solutions in water. Historically, it was extracted from the ashes of plants growing in sodium-rich soils. Because the ashes of these sodium-rich plants were noticeably different from ashes of wood (once used to produce potash), sodium carbonate became known as "soda ash". It is produced in large quantities from sodium chloride and limestone by the Solvay process. Hydrates Sodium carbonate is obtained as three hydrates and as the anhydrous salt: * sodium carbonate decahydrate (natron), Na2CO3·10H2O, which readily effloresces to form the monohydrate. * sodium carbonate heptahydrate (not known in mineral form), Na2CO3·7H2O. * sodium carbonate monohydrate (thermonatrite), Na2CO3·H2O. Also known as crystal carbonate. * anhydrous sodium carbonate ( n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural History (Pliny)
The ''Natural History'' ( la, Naturalis historia) is a work by Pliny the Elder. The largest single work to have survived from the Roman Empire to the modern day, the ''Natural History'' compiles information gleaned from other ancient authors. Despite the work's title, its subject area is not limited to what is today understood by natural history; Pliny himself defines his scope as "the natural world, or life". It is encyclopedic in scope, but its structure is not like that of a modern encyclopedia. It is the only work by Pliny to have survived, and the last that he published. He published the first 10 books in AD 77, but had not made a final revision of the remainder at the time of Pliny the Elder#Death, his death during the Eruption of Mount Vesuvius in 79 AD, AD 79 eruption of Vesuvius. The rest was published posthumously by Pliny's nephew, Pliny the Younger. The work is divided into 37 books, organised into 10 volumes. These cover topics including astronomy, mathematic ...

Pliny The Elder
Gaius Plinius Secundus (AD 23/2479), called Pliny the Elder (), was a Roman author, naturalist and natural philosopher, and naval and army commander of the early Roman Empire, and a friend of the emperor Vespasian. He wrote the encyclopedic '' Naturalis Historia'' (''Natural History''), 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. His nephew, Pliny the Younger, wrote of him in a letter to the historian Tacitus: Among Pliny's greatest works was the twenty-volume work ''Bella Germaniae'' ("The History of the German Wars"), which is no longer extant. ''Bella Germaniae'', which began where Aufidius Bassus' ''Libri Belli Germanici'' ("The War with the Germans") left off, was used as a source by other prominent Roman historians, including Plutarch, Tacitus and Suetonius. Tacitus—who many scholars agree had never travelled in Germania—used ''Bella Germa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Frogs
''The Frogs'' ( grc-gre, Βάτραχοι, Bátrakhoi, Frogs; la, Ranae, often abbreviated ''Ran.'' or ''Ra.'') is a comedy written by the Ancient Greek playwright Aristophanes. It was performed at the Lenaia, one of the Festivals of Dionysus in Athens, in 405 BC and received first place. Plot ''The Frogs'' tells the story of the god Dionysus, who, despairing of the state of Athens' tragedians, travels to Hades (the underworld) to bring the playwright Euripides back from the dead. (Euripides had died the year before, in 406 BC.) He brings along his slave Xanthias, who is smarter and braver than Dionysus. As the play opens, Xanthias and Dionysus argue over what kind of jokes Xanthias can use to open the play. For the first half of the play, Dionysus routinely makes critical errors, forcing Xanthias to improvise in order to protect his master and prevent Dionysus from looking incompetent—but this only allows Dionysus to continue to make mistakes with no consequence.

Aristophanes
Aristophanes (; grc, Ἀριστοφάνης, ; c. 446 – c. 386 BC), son of Philippus, of the deme Kydathenaion ( la, Cydathenaeum), was a comic playwright or comedy-writer of ancient Athens and a poet of Old Attic Comedy. Eleven of his forty plays survive virtually complete. These provide the most valuable examples of a genre of comic drama known as Old Comedy and are used to define it, along with fragments from dozens of lost plays by Aristophanes and his contemporaries. Also known as "The Father of Comedy" and "the Prince of Ancient Comedy", Aristophanes has been said to recreate the life of ancient Athens more convincingly than any other author. His powers of ridicule were feared and acknowledged by influential contemporaries; Plato singled out Aristophanes' play '' The Clouds'' as slander that contributed to the trial and subsequent condemning to death of Socrates, although other satirical playwrights had also caricatured the philosopher. Aristophanes' second pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
