PLAIN PICTURES PB by Joni Kinsey,University of Iowa. Museum of Art Pdf
Illustrated with 120 color and black-and-white reproductions showcasing works by George Catlin, Worthington Whittredge, Albert Bierstadt, Georgia O'Keefe and others, Plain Pictures is the first book to address representations of the midwestern prairie as a genre distinct from American western art. In a wide-ranging narrative, Kinsey argues that images of the grassland, far from being plain, offer a paradox of their own: the significance of the subject is equalled only by the struggle to express it.
The Lion’s Den (PB) By: Frank B. Atkinson The Lion’s Den is essential reading for anyone whose confidence in American democracy has been shaken by recent events. There is plenty to discourage and alarm us these days; the supply of negative political role models, real and fictional, seems endless. Frank Atkinson leaves no doubt that we can do better and be better. Just in time, it seems, he arrives with some exemplary political characters, a powerfully uplifting story, and a summons to get to work restoring the ethic of principled citizenship and service that reflects the ‘better angels of our nature’ and offers hope for bringing Americans together again.” - LARRY J. SABATO, Director, UVA Center for Politics The Lion’s Den offers a prescription for American renewal at a time of eroding confidence in our political institutions and growing confusion about our national purpose. In Frank Atkinson’s formulation, there are no quick fixes for our broken politics … no easy cure for what ails our democracy. A republic’s community spirit and capacity for constructive self-governance depend on a consensus about essential values and the active choice to practice, promote, and perpetuate those values. The ethic of principled citizenship and service that Atkinson considers indispensable for American renewal is not an inherited trait – like every ethic, it is a character requiring cultivation. And it is strongest when grounded in personal faith and integrity … illuminated by hard-learned lessons from history and experience … inspired by worthy human exemplars … propelled by the optimistic pursuit of a “more perfect union” … and kindled in a culture of mutual respect and forbearance guided by the “Golden Rule.” No starry-eyed idealist, Frank Atkinson’s major nonfiction works – The Dynamic Dominion and Virginia in the Vanguard – turned a candid lens on the hard-fought modern politics of his native state. In The Lion’s Den, he offers a compelling fictional account of life in the political arena – at once a venue for selfless contribution and palace of selfish ambition. Inspired by timeless lessons from the Book of Daniel, Madison’s vision of competition and compromise, and the colorful politics of his contemporary Commonwealth, Atkinson places his characters in a modern-day lion’s den where they grapple with vexing moral and practical choices. But Atkinson’s players find the grace to come together ... and, he suggests, so can we.
'Bursts with gloriously geeky detail.' The Telegraph Have you ever made someone you love a mix-tape? Forty years ago, a group of scientists, artists and writers gathered in a house in Ithaca, New York to work on the most important compilation ever conceived. It wasn't from one person to another, it was from Earth to the Cosmos. In 1977 NASA sent Voyager 1 and 2 on a Grand Tour of the outer planets. During the design phase of the Voyager mission, it was realised that this pair of plucky probes would eventually leave our solar system to drift forever in the unimaginable void of interstellar space. With this gloomy-sounding outcome in mind, NASA decided to do something optimistic. They commissioned astronomer Carl Sagan to create a message to be fixed to the side of Voyager 1 and 2 – a plaque, a calling card, a handshake to any passing alien that might one day chance upon them. The result was the Voyager Golden Record, a genre-hopping multi-media metal LP. A 90-minute playlist of music from across the globe, a sound essay of life on Earth, spoken greetings in multiple languages and more than 100 photographs and diagrams, all painstakingly chosen by Sagan and his team to create an aliens' guide to Earthlings. The record included music by J.S. Bach and Chuck Berry, a message of peace from US president Jimmy Carter, facts, figures and dimensions, all encased in a golden box. The Vinyl Frontier tells the story of NASA's interstellar mix-tape, from first phone call to final launch, when Voyager 1 and 2 left our planet bearing their hopeful message from the Summer of '77 to a distant future.
