Included are numerous mileage logs never before published, and many sketch maps made especially for this book. A unique system arranges the localities along segments of the main highways.

Latest information is given on local travel and collecting conditions and land ownership, so much desired by collectors who want to make the best use of their time. Gem and mineral societies that welcome visitors — museums that display outstanding collections — are all described. Official maps and references to the literature are listed.

"A fine treatment of this critical time in geology's history. Although it goes against our standard histories of the field, Laudan defends her views convincingly. Her style is direct, with carefully reasoned personal opinions and interpretations clearly defined."—Jere H. Lipps, The Scientist

Gleaming and perfect, gold has beguiled humankind for many millennia, attracting treasure hunters, adorning the living and the dead, and symbolizing wealth, power, divinity, and eternity. This book offers a lively, critical look at the cultural history of this most regal metal, examining its importance across many cultures and time periods and the many places where it has been central, from religious ceremonies to colonial expeditions to modern science.
           
Rebecca Zorach and Michael W. Phillips Jr. cast gold as a substance of paradoxes. Its softness at once makes it useless for most building projects yet highly suited for the exploration of form and the transmission—importantly—of images, such as the faces of rulers on currency. It has been the icon of value—the surest bet in times of uncertain markets—yet also of valuelessness, something King Midas learned the hard way. And, as Zorach and Phillips detail, it has been at the center of many clashes between cultures all throughout history, the unfortunate catalyst of countless blood lusts. Ultimately, they show that the questions posed by our relentless desire for gold are really questions about value itself. Lavishly illustrated, this book offers a shimmering exploration of the mythology, economy, aesthetics, and perils at the center of this simple—yet irresistible—substance.
