      Whether playing at defending their own castle or simply chucking pumpkins over a fence, wannabe marauders and tinkerers will become fast acquainted with Ludgar, the War Wolf, Ill Neighbor, Cabulus, and the Wild Donkey—ancient artillery devices known commonly as catapults. Building these simple yet sophisticated machines introduces fundamentals of math and physics using levers, force, torsion, tension, and traction. Instructions and diagrams illustrate how to build seven authentic working model catapults, including an early Greek ballista, a Roman onager, and the apex of catapult technology, the English trebuchet. Additional projects include learning how to lash and make rope and how to construct and use a hand sling and a staff sling. The colorful history of siege warfare is explored through the stories of Alexander the Great and his battle of Tyre; Saladin, Richard the Lionheart, and the Third Crusade; pirate-turned-soldier John Crabbe and his ship-mounted catapults; and Edward I of England and his battle against the Scots at Stirling Castle.

      Practical Pyromaniac
    • Der Autor ist bisher durch einen etwas fragwürdigen Titel ("Messerwerfen & Absinth", ID-G 36/10) hervorgetreten. Hier legt er einen populären Band zu antiken und mittelalterlichen Wurfmaschinen und Katapulten vor, das sich auf den zweiten Blick als ein Bastelbuch für die Modelle der beschriebenen Vorbilder entpuppt. Gurstelle geht davon aus, dass die Bauanleitungen nur in Zusammenarbeit mit versierten Hobbybastlern zum Erfolg führen. Die Texte zur Geschichte der alten Artillerie sind sehr einfach gehalten und orientieren sich vorrangig an der Systematisierung und Beschreibung der unterschiedlichen Waffenarten. Dabei passieren einige Patzer: Z.B. geht das Kapitel über die "Antike" bis ins Mittelalter, der Mont Ségur und die Albigenseraufstände werden nach Italien verlegt (statt Frankreich). Die technischen Beschreibungen der Waffen sind sehr allgemein, es fehlen u.a. Maße, Wurfgewichte, Reichweiten. Die Fotos von erhaltenen und restaurierten Wurfmaschinen bleiben ohne Bildunterschrift. In Ermangelung von Alternativen bedingt empfohlen. (3) (Helmut Lange)
