Special note: an earlier version of this post appeared on a new blog I helped develop in partnership with Not Even Past of the University of Texas at Austin and Origins (Ohio State University). Check it out here: historymilestones.tumblr.comOn September 8, 1404, the Castilian diplomat Ruy Gonzales de Clavijo reached the Silk Road city of Samarkand. He had travelled over five thousand miles by foot, sail, horse and camel; passed through steppe, deserts, seas and mountains. Now he had reached his destination: the capital of a vast new empire created by a military genius, mass murderer and patron of the arts named Timur (meaning “iron” in Persian). De Clavijo’s lord, King Henry III of Castile, had dispatched him to learn more about the man who Europeans called Tamurlane. If possible, he was to forge a peace treaty with the world-conqueror, whose sack of Baghdad alone caused the deaths of hundreds of thousands.

Modeling History: Making a Stiff-Board Parchment Binding with a Slotted Spine This post comes from the 2012 Gladys Brooks conservation intern, Morgan Adams. Morgan is currently interning in the Thaw Conservation Center at the Morgan Library & Museum As the 2012 Gladys Brooks intern I had the pleasure of working with Senior Book Conservator Anne Hillam on a model of a stiff-boards parchment binding with a slotted spine, a style seen commonly in Italian bindings of the 16th-17th centuries. An example of a stiff-boards parchment binding with a slotted spine from the NYAM collection: Trincavello, De differentiis febrium, Venice, 1585. Left: Back cover and spine. Right: Front cover.

Discussion Forums - Tamgas or not? Extraneous motifs on weavings Posted by James Blanchard on 03-30-2006 12:44 PM: Yomut mafrash - eagle symbol? Hi all, The Medieval Dance of Death There's an expression "to look like Death warmed over". The similar expression in Danish is "to look like Death from Lübeck". I have always wondered what this charming Christmas-city, with its great beer and overly sweet marzipan, had done to deserve such a disparaging sobriquet. "Death from Lübeck" was a 30 meter painting, showing Death in a long chain-dance with 24 humans - painted life-size - from all classes of society, from pope to infant. Death dances around in the procession, calling people to the dance, but most of the dancers-to-be try to decline. Pictures and text are combined so we have what may be one of the world's first and greatest comic strips.

Margaret Wertheim – The limits of physics Theoretical physics is beset by a paradox that remains as mysterious today as it was a century ago: at the subatomic level things are simultaneously particles and waves. Like the duck-rabbit illusion first described in 1899 by the Polish-born American psychologist Joseph Jastrow, subatomic reality appears to us as two different categories of being. But there is another paradox in play. The World of Dante Note: Many of these maps are viewable with a pan and zoom feature. Click the associated image to view the details.

The Science of "Chunking," Working Memory, and How Pattern Recognition Fuels Creativity by Maria Popova “Generating interesting connections between disparate subjects is what makes art so fascinating to create and to view… We are forced to contemplate a new, higher pattern that binds lower ones together.” It seems to be the season for fascinating meditations on consciousness, exploring such questions as what happens while we sleep, how complex cognition evolved, and why the world exists. Joining them and prior explorations of what it means to be human is The Ravenous Brain: How the New Science of Consciousness Explains Our Insatiable Search for Meaning (public library) by Cambridge neuroscientist Daniel Bor in which, among other things, he sheds light on how our species’ penchant for pattern-recognition is essential to consciousness and our entire experience of life. To illustrate the power of chunking, Bor gives an astounding example of how one man was able to use this mental mechanism in greatly expanding the capacity of his working memory.
