First published in 2012, this catalogue presents fifty-six Etruscan, Greek, and Italic carved ambers from the Getty Museum's collection—the second largest body of this material in the United States and one of the most important in the world. The ambers date from about 650 to 300 BC. The catalogue offers full description of the pieces, including typology, style, chronology, condition, and iconography. Each piece is illustrated. The catalogue is preceded by a general introduction to ancient amber (which was also published in 2012 as a stand-alone print volume titled Amber and the Ancient World). Through exquisite visual examples and vivid classical texts, this book examines the myths and legends woven around amber—its employment in magic and medicine, its transport and carving, and its incorporation into jewelry, amulets, and other objects of prestige. This publication highlights a group of remarkable amber carvings at the J. Paul Getty Museum. This catalogue was first published in 2012 at museumcatalogues.getty.edu/amber/. The present online edition of this open-access publication was migrated in 2019 to www.getty.edu/publications/ambers/; it features zoomable, high-resolution photography; free PDF, EPUB, and Kindle/MOBI downloads of the book; and JPG downloads of the catalogue images.

The fossilized resin of ancient trees, amber preserves organic material--most commonly insects and other invertebrates--and with it the shape and surface detail that are usually obliterated or hopelessly distorted during the mineralization we associate with fossils. This fascinating substance offers a unique intersection of the fields of paleontology, botany, entomology, and mineralogy.

A comprehensive manual of the world's gemstones and includes more than 1,400 examples. Opposite each illustration, this text provides a description of the particular stone, including details of the properties and chemical composition which makes the stone unique. It also gives information on location of major deposits, and alternative names.

The Newbery Medal–winning author of Good Masters! Sweet Ladies! gives readers a virtuoso performance in verse in this profoundly original epic pitched just right for fans of poetry, history, mythology, and fantasy. Welcome to ancient Greece as only genius storyteller Laura Amy Schlitz can conjure it. In a warlike land of wind and sunlight, “ringed by a restless sea,” live Rhaskos and Melisto, spiritual twins with little in common beyond the violent and mysterious forces that dictate their lives. A Thracian slave in a Greek household, Rhaskos is as common as clay, a stable boy worth less than a donkey, much less a horse. Wrenched from his mother at a tender age, he nurtures in secret, aided by Socrates, his passions for art and philosophy. Melisto is a spoiled aristocrat, a girl as precious as amber but willful and wild. She’ll marry and be tamed—the curse of all highborn girls—but risk her life for a season first to serve Artemis, goddess of the hunt. Bound by destiny, Melisto and Rhaskos—Amber and Clay—never meet in the flesh. By the time they do, one of them is a ghost. But the thin line between life and death is just one boundary their unlikely friendship crosses. It takes an army of snarky gods and fearsome goddesses, slaves and masters, mothers and philosophers to help shape their story into a gorgeously distilled, symphonic tour de force. Blending verse, prose, and illustrated archeological “artifacts,” this is a tale that vividly transcends time, an indelible reminder of the power of language to illuminate the over- and underworlds of human history.

Amber is the collective name for a suite of programs that allow users to carry out molecular dynamics simulations, particularly on biomolecules. None of the individual programs carries this name, but the various parts work reasonably well together, and provide a powerful framework for many common calculations. The term Amber is also used to refer to the empirical force fields that are implemented here. It should be recognized, however, that the code and force field are separate: several other computer packages have implemented the Amber force fields, and other force fields can be implemented with the Amber programs. Further, the force fields are in the public domain, whereas the codes are distributed under a license agreement. The Amber software suite is divided into two parts: AmberTools21, a collection of freely available programs mostly under the GPL license, and Amber20, which is centered around the pmemd simulation program, and which continues to be licensed as before, under a more restrictive license. Amber20 represents a significant change from the most recent previous version, Amber18. (We have moved to numbering Amber releases by the last two digits of the calendar year, so there are no odd-numbered versions.) Please see https://ambermd.org for an overview of the most important changes. AmberTools is a set of programs for biomolecular simulation and analysis. They are designed to work well with each other, and with the “regular” Amber suite of programs. You can perform many simulation tasks with AmberTools, and you can do more extensive simulations with the combination of AmberTools and Amber itself. Most components of AmberTools are released under the GNU General Public License (GPL). A few components are in the public domain or have other open-source licenses. See the README file for more information.

Students and practitioners of Chinese herbal medicine must learn hundreds of commonly used herbs as the first step in studying Chinese herbal medicine. Additionally, junior practitioners lack the clinical experience required to ensure that they can skilfully select the appropriate herbs to use in the formulas. This presents them with a major challenge. Chinese Herbal Medicines: Comparisons and Characteristics presents a method of learning individual herbs through vivid and clear discussion of their characteristics and through a comparison with other herbs of their characteristics and strengths. This clear and logical approach makes it easy for the user to understand and memorize the functions of specific herbs. It also enables experienced practitioners to improve their therapeutic results through the use of better formulas. Key features of the new edition - Retains the same easy to follow format as the first edition - Presents detailed comparisons and discussions of commonly used Chinese herbs - Provides a series of thought-provoking questions with very detailed answers - Structured to help the reader to learn and memorize the content more easily - The easy-to-use question-andanswer format is convenient to apply in the consulting room - Includes discussion of clinical applications to help with the practical use of the information in clinical setting - Revised and updated with particular emphasis on the safe use of Chinese herbal medicines - New appendices provide information on safe dosages, commonly used herbal combinations and the meanings of Chinese words used in herbal names - Provides a sound foundation for the study and practice of Chinese herbal medicine. Chinese Herbal Medicinse: Comparisons and Characteristics is already wellknown to students and practitioners of Chinese herbal medicine. This new, improved edition will continue to be of value to students and practitioners alike. It is now supported by a new companion volume by the same author entitled Chinese Herbal Formulas: Treatment Principles and Composition Strategies. Together these two books provide a sound foundation for the study and practice of Chinese herbal medicine. - Detailed and vivid comparisons and discussions of Chinese herbs to help the reader memorize and understand their characteristics - Structured as a series of thought-provoking questions with very detailed answers, again to help memorize the content - Includes "clinical applications" subsection within each section, to help the reader understand how to apply information better and more accurately in the clinical setting.
