Klangfiguren, 1787

One of Chladni’s best-known achievements was inventing a technique to show the various modes of vibration of a rigid surface. First published in 1787 in his book Entdeckungen über die Theorie des Klanges, the technique consists of drawing a bow over a (circular, square, or rectangular) plate or membrane whose surface is lightly covered with sand. When stroked, a given plate will resonate at one of its natural frequencies. The sand bounces about on the plate until settling at nodal points (areas of zero movement) thereby producing intricate patterns. These patterns are now called Chladni figures.

Die Akustic, 1802

Nodal lines of vibrating circular or polygonal  plates, acording to Chladni and Savart. The breakthrough work acquired a status of foundational work of a new scientific field and earned him a title of “father of acoustics”. It was the first systematic description of the vibrations of elastic bodies. see the full archive on geometrymatters.com

Early Medieval pattern-welded Sickle

Reconstruction by Thorkil

The sickle was based on an antler sickle case found in Stargard Szczecinski, West Pomerania (Poland). The original was richly decorated with geometrical motives, popular at that time. Thorkil’s version is a very faithful reconstruction of it, with all circles, dots, triangles and lines made on natural deer antler.

The decoration was hand engraved, then coloured with natural dark dye for a contrast and stronger effect. The sickle blade’s is pattern-welded (damascus) steel. It was hand forged (in charcoal fire) of 20 twisted layers. The cutting edge was forge-welded to pattern-welded part.

Hello! I have a plan to get my main character injured by the antagonist. But, since the mc lives, is it better to describe the danger or get the mc injured so he (and the audience) would have no questions about the seriousness of the antagonist?

When to Injure Your MC

If you ask many writers why they beat their characters up so much, the immediate playful answer might be “Because it’s fun!” but there is (or should be) some strategy involved in when and how you injure your main character. So before I answer the question directly, I’m going to discuss these strategies a little.

Reasons to Injure a Character:

1. To create additional challenges in a high-stakes situation

If a character’s journey has been fairly easy to far, an injury is one way to complicate things. But the only way it works is if the injury lasts long enough to really hinder them. 

For instance, if you have a character that has the magical ability to heal others, then a character being injured and then healed two minutes later doesn’t create much of a challenge, nor does it heighten suspense since the character’s life was never truly in danger. So an injury that’s introduced to complicate things should take some time to recover from, and it’s usually more realistic anyway, especially when you consider the tortuous stuff we do to our MCs sometimes.

However, if you do have a healer character, and they’re currently separated from the character you injure, then a challenge is immediately presented. The injured character has to continue their journey through the injury, to either reach their destination or be reunited with the healer that can help them. 

2. To foreshadow a future situation

The situation I described above, where a character is injured and then healed two minutes later, could work, if it’s being used to foreshadow the second situation I described, where the two characters are separated. Showing the healer in action early in the story can foreshadow a later complication when the healer is unable to assist their companion, whether it’s due to a separation or a sudden loss of powers. 

It can also work as exposition to show the way the healer’s power works. 

3. To show the antagonist’s maliciousness 

The anon above suggested they injure their character to show the antagonist means business, and that definitely qualifies as a good reason to injure a character.

See, when an antagonist hurts a character - and not just an MC, but anyone - they show that they don’t care who gets in their way. They want what they want, and in their opinion, the ends justifies the means. Even when a character isn’t necessarily in their way, and they do it for pleasure, it tells a reader a great deal about the antagonist’s psyche, and how far they’ll go to further their own agenda. 

My only caution here is to be wary of how often you’re using this reason. Often times it becomes easy to justify an antagonist’s plan by saying “They’re evil and they enjoy torturing people.” But villains who are evil just for the pure enjoyment of it grow uninteresting and predictable quickly. So despite the pleasure they get out of hurting people, they must have some greater scheme in front of them. Some ultimate gain that they’re hoping to achieve. A combination of these two things can breed a fascinating antagonist. 

4. To deepen a character bond or relationship

Injuries or illness are great opportunities to write a dynamic where one character is taking care of another, showing how close the two characters are, and how attentively they’ll care for the other. But this dynamic is most compelling when it’s a reversal, such as a little brother taking care of an older one, or when someone who the protagonist has built up to be invincible is suddenly sidelined and needs the protagonist’s help. 

Like the previous reason, i would just be careful how frequently this occurs. Situations like these are more effective when they’re big, and they last long term, rather than several smaller instances where a character keeps getting hurt and cared for. 

There may be other reasons out there to justify injuring a character that I haven’t thought of here, but I can surely tell you one reason not to:

Avoid injuring a character purely for the fun of it. 

Now listen, what you do in your own private writing universe is your own business, and if you want to put your characters through hell because it’s fun, I commend you for finding so much joy in the process of writing and I encourage you to keep at it. But when it comes to finding an audience, and telling a cohesive, well-paced, well-plotted story, you gotta start considering each move you make as a writer, and ask yourself if each plot point needs to be there. 

Back to the anon…

Now that I’ve gone into all this detail, let me get back to the specific question that the anon asked. Since the character ultimately lives, is it better to just show the possible danger, or to actually have the antagonist injure them to show they’re serious?

My answer to you would be that you could injure the character, since your reasoning falls within the reasons I listed here (reason #3), and it would be even better if it qualified for two reasons, such as delaying their progress to achieve their goal (reason #1) or repairing a strained relationship when a companion must take care of them (reason #4). 

Your argument that the character lives (so why bother?) ignores the need for conflict in a story. Readers appreciate conflict, as long as there are logical reasons for it, and if you consider these reasons I discussed, you should be in great shape. 

However, I think that you could show your antagonist’s malicious intentions without injuring the character, if you felt the injury would be too much for an already conflict-heavy plot. The antagonist might show anger/violence towards the people working for them (out of frustration), or even to innocent bystanders, or other minor characters whose fates we’re not as tied up in. So I think there are still options for you if you wanted to avoid an injury.

Why do artists refuse to use references why why why.

It’s not a contest to see who can get by without them. It’s not cheating to look at a thing in order to know what the thing looks like.

You don’t get stronger or better by pretending. Nobody is impressed by the awkward whatever-it-is you just drew. Use references.
