also come in many sizes, actions, hardness and configurations depending on whether they are to be used for small, medium or large fish or in different fresh- or saltwater situations. Various types of fishing rods are designed for specific subtypes of angling, for instance: spin fishing rods (both spinning and baitcasting rods) are optimized for frequent, repeated casting, and are usually lighter and have faster action; fly rods are designed to better sling heavy lines and ultralight artificial flies, and are usually much more flexible; surfcasting rods are designed to cast baits or lures out over far distances, and tends to be quite long; ice fishing rods are designed to fish through small drilled holes in ice covered lakes and usually very short; and trolling rods are designed to drag heavy bait or lures through water while boat fishing, and usually have greater ultimate tensile strength due to the large sizes of the target fish. History Judging by stone inscriptions dating back to 2000 BC, fishing rods go back to ancient Egypt, China, Greece, Trinidad and Tobago, Rome and medieval England. Fly fishing The art of fly fishing took a great leap forward after the English Civil War, where a newly found interest in the activity left its mark on the many books and treatises that were written on the subject at the time. The renowned officer in the Parliamentary army, Robert Venables, published in 1662 The Experienced Angler, or Angling improved, being a general discourse of angling, imparting many of the aptest ways and choicest experiments for the taking of most sorts of fish in pond or river. Compleat Angler was written by Izaak Walton in 1653 (although Walton continued to add to it for a quarter of a century) and described the fishing in the Derbyshire Wye. It was a celebration of the art and spirit of fishing in prose and verse; six verses were quoted from John Dennys's earlier work. A second part to the book was added by Walton's friend Charles Cotton. The 18th century was mainly an era of consolidation of the techniques developed in the previous century. Running rings began to appear along the fishing rods, which gave anglers greater control over the cast line. The rods themselves were also becoming increasingly sophisticated and specialized for different roles. Jointed rods became common from the middle of the century and bamboo came to be used
