The Writer’s Guide: Introduction to Sailing Ships

There is something romantic, magical even, about sailing ships. Vessels with motors lack a certain enchantment. It should come as no surprise that writers love to include sailing craft in literature and many an adventure yarn starts with boarding a ship. The vessel can be a vital part of the story, such as the Hispaniola in Robert Louis Stevenson’s Treasure Island, or just an enchanting element like the silver ship that carries Frodo and Bilbo into the West at the end of The Return of the King.

Yet since most people do not have hands-on experience with sailing, the average writer knows little about them. In this series, I will cover a wide sweep of topics, including the technology of the sailing ship, navigation, and the history of sailing. For today, I will go through the basics.

As always, magic is the exception to the rule. Because magic.

Basic Terminology

Ships and sailing have their own terminology, which can sound like their own language.

Hull – The outer body of the ship. Hulls come in a variety of shapes and can be made of wood, metal, or fiberglass.

Keel – The bottom structural ridge of the hull. It strengthens the hull and can serve a hydrodynamic or counterbalancing function.

Deck – The top floor and one that forms a ceiling over the compartments and cabins on the decks below. It helps hold the hull together, protects the lower decks from the weather, and is the main working surface for the crew. Not all ships have decks, with those that don’t use the inside of the hull as a deck.

Mast – A vertical spar secured to the deck that supports the sails. They were originally made of wood, commonly entire tree trunks, but have also been made of metal and fiberglass.

Yard – A horizontal spar attached to a mast from which sails are suspended. They are mostly used on square-rigged sails.

Sail – A large sheet of fabric suspended from a mast or yard used to catch the wind.

Rigging – The series of ropes, cables, and chains that secure the sails, yards, and masts. There are two types: standing and running. Standing rigging is fixed in position while running rigging is tightened or loosening to change the shape and position of the sails.

Rudder – A flat fixture on the back of a boat below the waterline that is adjusted to change the direction of the vessel.

Wheel – The device that controls the rudder. It is on the deck at the back of the ship.

Forecastle or Fo’c’s’le – A raised deck at the front of a ship. Forecastles can be only slightly higher than the main deck or significantly taller. Medieval ships had fortified raised front decks that looked like castles. In the following centuries, the name forecastle was shortened to fo’c’s’le.

Quarter Deck – A raised deck behind the mainmast. Traditionally, it was the location from which the captain commanded the vessel.

Poop Deck – A tall deck at the rear of a ship. It was usually taller than the quarterdeck and originally fortified like the forecastle. The name comes from the French word la poupe, which means stern, since it is at the back.

Anchor – A heavy device used to secure a vessel to the bottom of the ocean or other body of water. This prevents the craft from drifting with the wind or current.

Port – The left side of a ship.

Starboard – The right side of a ship.

Bow – The front of a ship.

Stern – The back of a ship.

Writer’s Deep Dive: Toledo Steel

Damascus, Syria was not the only city that became famous for its steel. Toledo, Spain was also producing high quality and highly valued blades from ancient times.

Now, let’s dive in!

What is Toledo Steel?

Toledo steel was famous for being flexible and strong and its production was a closely guarded secret until the 20th century. It started with the metals. An envelope of steel was folded around a wrought iron strip, which gave the metal the strength of the steel and the flexibility of the iron. The combination of metals was heated, and forge welded together. This technique is called san mai by modern bladesmiths and is often used when forging swords and knives. It’s also known as the “taco” method. Because of this technique, Toledo steel was said to have a “soul of iron.” [1]

The second secret was the production with a strict schedule of heating, cooling, and temperature. If the process was not followed exactly, the blade would not be of the highest quality. Originally, prayers and psalms were carefully recited with the same rhythm to keep the timing. This process was long and difficult and the average bladesmith produced two to three weapons per year.

History

Historians are unsure when the peoples of Iberia began making Toledo steel, but the tribes of ancient Hispania were famous for a type of sword known as a falcata. It was thought to be more fatal than other weapons. [1] The steel and style of sword became prized by the 3rd century when Hannibal choose to arm his soldiers with them during the Second Punic War. The Romans were impressed by their quality and later made Toledo the standard source of steel for their legions. [2]

The production of Toledo steel continued under the Muslin occupation of the Iberian Peninsula but reached its peak in the 15th and 16th centuries after the Christians regained control of southern Spain. [3]

However, as armies replaced their swords with guns, blacksmithing and bladesmithing began to die out. In 1761, King Carlos III of Spain ordered the creation of the Royal Sword Factory in Toledo to preserve the techniques and methods of steel production. [4] Unfortunately, the art has continued to decline and as of 2021, only one master swordsmith remained in Toledo. [5]

Besides Hannibal and his army, other famous warriors to carry Toledo swords include El Cid with his swords, Tizona and Colada, Emperor Charles V, and Charlemagne. Also, the ceremonial sword of the Catholic monarchs used to knight Christopher Columbus was Toledo steel. [1]

The sword claimed to be Tizona on exhibit at the Army Museum in Madrid. Image source.

The Write Angle

Sword-making cities can be a fantastic inspiration for fantasy writers. Is there a unique type of metal or weapon in your novel? Is there a famous forge or city of bladesmiths? Does your hero or heroine carry a legendary sword with a name?

The Writer’s Guide to Casting Metal

While blacksmithing may be the most well-known method of shaping metal, casting is a craft just as ancient. Casting can also produce intricate shapes that a blacksmith cannot match. Casting is commonly represented in fiction, especially in the “gearing up” scenes, although many of those scenes are inaccurate.

As always, magic is the exception to the rule. Because magic.

History

As I mentioned in my Writer’s Deep Dive: Metalworkers, the oldest cast piece is a copper frog from 3200 BC, that was found in Mesopotamia. [1] However, it is believed that the origins of metal casting are rooted in Southern Asia, specifically China, India, and Pakistan. [2] Most of these early pieces were tools, weapons, and religious statues.

Ancient people commonly added lead when casting copper because it made the molten copper more fluid, allowing them to cast more intricate designs. An example is the dancing girl statue from Mohenjo-daro. [3]

India was the first to use casting to mass produce coins, starting with silver but switching to copper alloy. They stacked multiple coin template molds in a clay cylinder and poured molten metal down the center. This method produced one hundred coins at once. [3]

Types of Casting

Lost Wax Casting – This method is used to create a replica. A mold is made from the original and from the mold, a wax or paraffin cast is made. The wax is covered in a fireproof material such as clay, then heated upside down so that the wax runs out or is “lost.” Then the remaining clay mold is filled with molten metal. The original object can either be a carved wax model or a finished piece, such as a metal statue.

This method of casting is one of the most ancient. The oldest examples of lost wax casting are gold artifacts that were found in Bulgaria. [4] A record was found on a clay tablet in Sparta, Babylon that specified how much wax was needed to cast a key. [5] This technique was adopted early in the Middle East and West Africa. China and Western Europe adopted the method much later. [3]

Mold Casting – Also known as molding, this process involves pouring molten metal into a rigid mold. Early molds were made of stone or ceramic. Articulated molds had multiple pieces that assembled to form a complete mold. [6] One method, known as piece-molding, used different molds to create separate pieces that were joined. Larger pieces such as statues were cast in pieces rather than the whole being cast at once.

Writer’s Tip: It has become common to see mold casting used to create swords in many fantasy movies and TV shows. However, mold casting is not a suitable method for creating a sword. Forging and tempering produce much better blades. Casting can produce good quality spearheads.

Sand Casting – A form of mold casting, this method uses an impression made in sand as the mold rather than a carved stone or molded ceramic mold. The sand is commonly mixed with clay to help it hold its shape. Molds made of sand are cheap, but they wear out faster than a stone or ceramic mold and also cannot produce the fine detail that other methods can.

Plaster Casting – This method is like sand casting but uses plaster instead of sand for the molding material. It can only be used with non-ferrous materials. The metal cools more slowly with this method than with sand casting, allowing time for the metal to fill thin cross-sections, creating more complex and detailed parts. [7]

Other Methods – There are more modern methods of casting that I have not covered. I choose to highlight those used during the ancient and medieval periods. Other methods include die casting, centrifugal casting, investment casting, rapid casting, and squeeze casting.

Finishing

Once the raw castings are released from the mold, they must be finished. The primary work is removing the unwanted extra metal, which includes the access port through which the metal was poured. This process is known as fettling and is often time-consuming. [8] After that, the piece is smoothed with filing or grinding and assembled, if it has multiple parts.

Writer’s Deep Dive: Damascus Steel

Damascus steel blades have been prized for their sharpness, durability, and balance of hardness and flexibility. Throughout history, steel has been valued, upheld as a gift from the gods. Yet Damascus steel has a legendary status and to this day is ascribed near-mythological properties.

Now, let’s dive in!

What is Damascus Steel?

Damascus is a high carbon steel alloy that exhibits a unique pattern when forged. [2]

The metal was developed in southern India and Sri Lanka during the mid-1st millennium BCE and was known as Wootz steel or Seric steel. A mixture of cast iron (also known as pig iron), iron, and sometimes steel was heated to extreme temperatures in a crucible that was commonly made of clay. [1] Often sand, glass, ashes, and other fluxes or cleaning agents were added to the mixture. The charcoal or coal fires in use at the time could not produce temperatures high enough to melt steel. They could, however, melt cast iron. As the iron or steel sat in the melted cast iron, they absorbed its carbon, creating a composite. The hot metal was then poured into molds to form ingots or billets. [3]

However, the mix of metals in these ingots was irregular and the carbon unevenly dispersed. To spread the mixtures of metals more evenly, during the forging process, the billet was drawn out, then folded back on itself hundreds or even thousands of times. Rather than quenching, the blades were commonly hardened by repeated heating and air cooling in a process called thermal cycling. Filing and polishing a forged Damascus blade revealed an intricate pattern. Often the banding is reminiscent of flowing water, but other patterns, such as “ladder” and “rose” were possible. This distinct patterning is the hallmark of Damascus steel. Unlike etched metal, the swirling pattern runs through the entire blade and not just the surface. If a Damascus blade is cut or broken, the pattern is visible in the cross section. Throughout history, multiple cultures have referred to Damascus as “watered steel.” They were also called “damascene” or “damascened” swords. [6]

The City that Named a Steel

There are several theories about the origin of the name “Damascus.” The most common is that it was named as the capital city of Syria that became famous for its swordsmiths. [4] The city of Damascus became the primary customer for ingots of Wootz steel from India and Sri Lanka and a leader in blade making from the 3rd to the 17th century. [5]

Other theories claim the name is derived from “damas,” the Arabic root word for “watered” and the origin of the word “damask.” There are also records of a swordsmith named Damasqui who used crucible steel. [7]

Over time, the production of Damascus swords declined. The last account is from Sri Lanka in 1903 by Coomaraswamy. [8]

Crucible Steel Versus Pattern Welding

Beginning in the 18th century, some gunsmiths began using the term Damascus steel for their pattern-welded gun barrels.

Pattern welding involves stacking and welding hard and soft metals together to form a billet, which is then drawn out and folded. Sometimes decorative patterns are cut into the metals to create complex designs. Pattern welding dates to the first millennium BC and was used by the Celts and Vikings. [9]

Although similar in appearance, pattern welded steel is not the same as Damascus. Crucible steel is harder and more time-consuming to produce. Unfortunately, a lot of pattern wielded steel is marketed as Damascus nowadays as well as surface etched blades.

The Writer’s Guide to Types of Metals

The metal used in the forging process is just as important as the item being made. Poor quality will cause bent blades or dull tools. Today, I will explore the most common metals found on our planet and some of their history. This is not an exhaustive list and does not mean you cannot make up your own metals for your world.

As always, magic is the exception to the rule. Because magic.

Naturally Occurring Metals

Gold – A “free” metal that can be found in caves and rivers, gold was the first worked by humans according to the earliest records. [1] This metal occurs naturally around the world and was used by many ancient civilizations for jewelry and other decorations, including those in Egypt, India, the Middle East, and North and South America. [2] Once it is extracted, gold is refined to remove impurities. Refining involves heating the metal to a molten state and skimming off the slag that rises to the surface. Gold can also be mixed with other metals to form an alloy and can only be tempered through work hardening.

Silver – Like gold, silver is a naturally occurring metal that can be found in the earth’s crust. It can also form an alloy with other metals. Silver is a byproduct of refining gold, copper, lead, and zinc. Throughout history, it was mainly used as ornamentation or currency and was in use in Europe, Asia, and the Middle East. [3] It also became a critical component of early photography because of its photosensitivity.

Copper – This was the first metal that was smelted, around 5,000 B.C., and cast into shape, around 4,000 B.C. [4] It was also the first to be successfully used to create weapons, although it was also used decoratively. It could only be tempered by work hardening and could be combined with other metals to form alloys. Most commonly, it was mixed with tin to form bronze. The earliest evidence of worked copper is a pendant that dates from 8,700 BCE and was found in northern Iraq. [5]

Iron – Iron in a metallic state is rare on earth but can be found in abundance within iron ores. The primary source of metallic iron is meteorites, which were prized by ancient civilizations. A dagger made of meteoric iron was found in the tomb of the pharaoh Tutankhamun. [6] Removing iron from ore is known as smelting and requires kilns or furnaces that can reach a temperature of 2,730 ° F (1,500° C). After that, iron can be worked hot in a forge. The earliest evidence of iron working has been found in Mesopotamia and Syria and dated between 3,000 and 2,700 B.C. [7]

Tin – This metal is soft and malleable and can be bent with little effort. There are few artifacts that have been found made solely of tin since most tin was mixed with copper to form bronze. Tin is unevenly dispersed around the globe with the richest source being Europe, most notably the border region between Germany and the Czech Republic, the Iberian Peninsula, Brittany in France, and southwestern Briton. There is evidence of trade in tin from Cornwall by the Late Bronze Age. [8]

Lead – Lead is a soft and easily worked metal, but as a heavy metal, it is denser than others. This metal is easily extracted from ores and is a byproduct of silver smelting. [9] It was used by the ancient peoples of the Middle East and throughout history lead has been used in plumbing, bullets and shot, batteries, making pewter, and cosmetics.

Alloys

Bronze – Bronze is a mixture of copper and most commonly tin, although arsenic, aluminum, manganese, nickel, or zinc could also be used. It is harder than copper, more resistant to corrosion, and has a lower melting point, making it easier to melt and cast. [10] Bronze cannot be tempered with heat but must be work hardened. This metal was a game changer for ancient civilization because it could be crafted into harder and more durable tools, weapons, and armor. The earliest bronze artifact comes from Serbia and dates to 4,650 B.C. [11]

Steel – This metal is an alloy of iron and carbon. There is evidence of limited production from Anatolia from as far back at 1,800 B.C. [12] Steel has high tensile strength and is low cost to produce. The use of the bloomery smelter and crucibles were developed as the best method to process steel and the early masters were in Sri Lanka. They were using these advanced methods by the 6th century BC. [13] This steel was known as Seric Iron or Wootz steel and it was exported to the Romans, Egyptians, Arabs, and Chinese. [14] Later it was called Damascus and is still prized today for its durable sharp edge. Eventually, the knowledge of how to create steel spread throughout the Old World, across Asia, the Middle East, Africa, and Europe.
