Richard Wagner's vast Der Ring des Nibelungen cycle comprises four full-length operas (Das Rheingold, Die Walkure, Siegfried and Gotterdammerung) and is arguably the most extraordinary achievement in the history of opera. His own libretto to the operas, translated by Andrew Porter, is an intricate system of metric patterns, imaginative metaphors and alliteration, combining to produce the music in text.

“This book shows how a flight to Mars has progressed from fantasy to … a reality that can be achieved by us. Zubrin is showing us the way.”
-- Buzz Aldrin
Just in time for the Mars Science Lab mission
Since the beginning of human history, Mars has been an alluring dream – the stuff of legends, gods, and mystery. The planet most like ours, it has still been thought impossible to reach, let alone explore and inhabit. But all that changed when leading space exploration authority Robert Zubrin crafted a daring new blueprint, Mars Direct. When it was first published in 1996, The Case for Mars became an instant classic, lauded widely for its game-changing perspective by those who would see the American space program rise to the challenge of Mars; Carl Sagan called Zubrin the man who, “nearly alone, changed our thinking on this issue.” Now, fifteen years later, Zubrin brings readers up to date in this revised and updated anniversary edition filled with spectacular illustrations, extraordinary photographs, and one-of-a-kind anecdotes.
Unlike the dead world of the Moon, the Martian landscape is filled with possibility, but humans must be able to survive there. In the grand tradition of successful explorers, Zubrin calls for a travel-light and live-off-the-land approach to Martian settlement. He explains how scientists can use present-day technology to send humans to Mars; produce fuel and oxygen on the planet’s surface with its own natural resources; build bases and settlements; and one day terraform – or alter the atmosphere of the planet in order to pave the way for sustainable life. As the landmark mission of the Mars Science Laboratory begins, Zubrin lays out a comprehensive plan to build life on a new world.

"Lettre sur la musique" de Richard Wagner. Compositeur, directeur de th��tre, pol�miste et chef d'orchestre allemand de la p�riode romantique (1813-1883).

A série ganhadora do Prêmio Eisner O Anel do Nibelungo , compilada pela Editora Pipoca & Nanquim em um único volume, apresenta uma das maiores narrativas da civilização ocidental e, agora, um dos épicos mais explosivos da história dos quadrinhos! Gigantes tramam contra deuses que, por sua vez, destroem romances humanos, enquanto a vida de grandes guerreiros é arruinada, e assassinatos após assassinatos são cometidos em nome do amor e do ouro. Cobiça, traições e disputas colidem num mundo onde deuses e homens caminham lado a lado. Este ponto alto da longeva e distintiva carreira de P. Craig Russell inclui artes de bastidores, notas da adaptação feitas pelo artista e esboços nunca vistos. É o épico definitivo exatamente como deve ser lido. “A bela versão de P. Craig Russell para o ciclo do Anel consegue ser o mais fiel e inspirador retrabalho de uma ópera em formato de quadrinhos, e a saga de alta fantasia definitiva.”- Neil Gaiman
