On a dusty football pitch known as Freedom Square, thousands of young Dinka men, coated with ash and clad in glamorous calfskin skirts, gather to elect a sub-chief.
Despite their differences, these maps enjoy some intriguing similarities, largely for the way they illustrate the priorities of their authors.The medieval Mappa Mundi in England's Hereford cathedral, for example, is little more than drawings on vellum, or stretched calfskin, and it lacks Ptolemy's geometric method.
Not content with flogging calfskin trench coats online, she has deployed every platform, device or bit of software she could think of to romance customers and spark collaboration among employees and suppliers.
The classical approach to bookbinding involves the use of dyed calfskin or goatskin laid over with contrasting colour; the tooling is either gold or blind (meaning no gold is used).
The use of paper spread slowly, however, and most of the oldest surviving manuscripts are of other materials, particularly vellum (fine-grained lambskin, kidskin, or calfskin).
The membrane, of calfskin or synthetic material, is secured by a metal hoop.
Character-type pieces were metallic and apparently cast from metallic molds; paper and vellum (calfskin parchment) were used to carry the impressions.
By the 16th century, screws were placed around the circumference of copper shells to control tensioning and tuning of the calfskin heads.
The heads, beaten with two tapered sticks ending in small knobs of wood or nylon, are of calfskin or plastic.
This is a rectangular piece of wood, about 9 by 6 inches (23 by 15 centimetres) in size, which is padded with flannel and covered with dressed calfskin; a parchment shield around one end protects the delicate leaf from disturbance by drafts of air.
The white walls and bleached-blonde wood floors evoke a feeling of serenity, light and space, which is suddenly punctuated - thanks to an impromptu trip to Paul Smith Home - by a fire-red Pierre Cardin sideboard and calfskin coffee table.
