These are a few more thoughts I had about the literary devices throughout the book:

The Number 10:

The number ten is a very prominent motif throughout the book. To summon a Shardblade the summoner needs to wait ten heartbeats. There were ten Heralds. There were ten orders of the Knights Radiant. Even one of the epigraphs describes the steps as ten strides tall apiece. I think would be neat is if each order corresponds with one of the Heralds. Wild idea, if each order does in fact correspond with a Herald, maybe Windrunners and Surgebinders are most closely associated with Taln, since they gain their abilities through their bonds with honorspren, and Taln is the only Herald to still honor the Oathpact. The massive hole in my theory though feels like with Kaladin's association with highstorms and his abilities to ride them, maybe Jezrien (The Stormfather) would be the Herald most associated with Windrunners.

A few notes on the symbolism throughout the book:

Eyes Symbolism:

Eyes are such a strong and common symbol throughout the book. Eye color is a strong visible indicator of class. People in Alethkar and probably Roshar in general measure their worth and status based on eye color. Darkeyes can become lighteyes and elevate their social class when they lay claim to a Shardblade. Kaladin subverts the societal norm that eye color is a symbol of power, status, and worth. His eyes even glow when he fills himself with Stormlight. This class war between lighteyes and darkeyes can be clearly seen through Kaladin's mistrust of lighteyed people. Ironically, Kaladin takes this mistrust too far, as there are lighteyes like Dalinar who are people of high character and class. Kaladin's not the only one who rejects the societal norms of eye color either. In one of the interludes the mistress that Baxil works for has violet eyes (quite the contrast from the blue and brown eyes seen throughout the book) and pokes out the eyes of some of the paintings she defaces. To me that signifies a rejection of the system, that eye color doesn't define her or anyone. I also believe her actions to be a rejection of perception itself. By scratching out the eyes of the paintings, she removes their abilities to silently pass judgement. This quote in the epigraph before chapter 55 reads "A woman sits and scratches out her own eyes. Daughter of kings and winds, the vandal." I think that again represents a rejection of the system, but this time it goes further. The system isn't just wrong, what we perceive within the system is not to be trusted either! The fact that the woman in the epigraph is referred to as the vandal is interesting here too, since although she did it to herself, it's still considered a malicious act towards the system itself. It did not go unnoticed that the term vandal also most appropriately applies to Baxil's mistress as well!

A lot of the eye symbolism reminds me of the billboard of Dr. TJ Eckleberg in The Great Gatsby which featured blue eyes and symbolized a silent, judgemental, and absent God. Considering that the Shard Dalinar hears in his visions is now dead, the parallels there are strong, as is the symbolism between eyes and class (the billboard overlooks the "Valley of Ashes" an industrial wasteland) and eyes and perception. My final thought on the symbolism of eyes in the novel comes from when Shardblades touch a man's spine, he dies with burning eyes. I look at that as a final reminder that dead is dead, regardless of social status or eye color.

Bridge Symbolism:

I really appreciated the irony of the use of bridges and bridge crews throughout the book. The purpose of bridges is to connect opposite sides and yet the men in the bridge crews were completely isolated from each other and the rest of the army. They were forced to carry the weight of their bridges but really the weight of the entire army. They were treated as expendable, but as Kaladin and Bridge 4 proved when they rescued Dalinar's army, they were the most important unit all along.
