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.<br></div> 216557 1 7 2004 The Art of the Catapult: Build Greek Ballistae, Roman Onagers, English Trebuchets, and More Ancient Artillery total:13|5:2|4:5|3:6|2:0|1:0| 13 48 35 1 4 0 false false Sun Jul 01 00:00:00 -0700 2007 Wed Sep 05 12:35:22 -0700 2007 Wed Sep 05 12:39:22 -0700 2007 more...]]> 0 0 false false Tue Dec 01 15:25:27 -0800 2009 Tue Dec 01 16:05:23 -0800 2009 0 0 false false Tue Nov 24 08:20:29 -0800 2009 Tue Nov 24 08:20:29 -0800 2009 0 0 false false Thu Oct 15 21:08:38 -0700 2009 Thu Oct 15 21:10:33 -0700 2009 5 0 false false Thu Oct 08 19:51:16 -0700 2009 Thu Oct 08 19:51:16 -0700 2009 0 0 false false Mon Jun 15 13:03:44 -0700 2009 Mon Jun 15 13:03:44 -0700 2009 3 0 false false Tue Jun 02 03:21:23 -0700 2009 Tue Jun 02 03:21:23 -0700 2009 3 0 false false Tue Jan 10 00:00:00 -0800 2006 Tue May 12 10:24:35 -0700 2009 Tue May 12 17:53:15 -0700 2009 0 0 false false Mon May 11 14:18:15 -0700 2009 Mon May 11 14:18:21 -0700 2009 0 0 false false Thu Apr 16 15:29:56 -0700 2009 Thu Apr 16 15:29:56 -0700 2009 4 0 false false Sun Mar 08 16:47:07 -0700 2009 Sun Mar 08 16:47:07 -0700 2009 0 0 false false Tue Jan 27 17:16:16 -0800 2009 Tue Jan 27 17:36:19 -0800 2009 0 0 false false Thu Jan 08 18:04:06 -0800 2009 Thu Jan 08 18:04:06 -0800 2009 0 0 false false Wed Jan 07 07:48:07 -0800 2009 Wed Jan 07 07:48:12 -0800 2009 0 0 false false Sat Dec 06 19:45:49 -0800 2008 Sat Dec 06 19:45:49 -0800 2008 0 0 false false Mon Oct 13 09:29:04 -0700 2008 Mon Oct 13 09:29:04 -0700 2008 0 0 false false Wed Oct 01 09:23:22 -0700 2008 Wed Oct 01 09:23:32 -0700 2008 0 0 false false Tue Sep 30 18:17:53 -0700 2008 Tue Sep 30 18:17:53 -0700 2008 4 0 false false Tue Sep 23 15:27:36 -0700 2008 Tue Sep 23 15:27:36 -0700 2008 3 0 false false Tue Jul 29 09:47:47 -0700 2008 Tue Jul 29 09:47:47 -0700 2008 http://www.goodreads.com/book_link/follow/8?book_id=223606
