And in the end, we found 65 accounts of it in ancient literature by 40 different authors. So we have literary descriptions. And then we looked at ancient art, and we were able to identify about 1,000 images in ancient art in vase paintings, pottery, bronze sculpture, tomb paintings, all these different things showing this armor.

And then using those two things, we tried to backward engineer a pattern to say, well, if this is what the end product looked like, what does it have to look like when you make it? And then we tried to reconstruct one of these things using only the glue and materials. So we had to use animal glues, rabbit glue. We had to end up sort of making our own linen, which comes from the flax plant.

So we had to grow flax, harvest it using only techniques in the ancient world. So modern flax goes through chemical processes. No, we had to do this the old fashioned way, spin it into thread. So the thread into fabric, glue it all together. And then the fun part was once we made these things, we subjected them to ballistics testing.

So we shot them with arrows, which again were wooden reconstruction arrows using bronze arrowheads that were based on arrowheads found on ancient battlefields to determine how good protection would this thing have been.

And of course, the kind of fun one that everyone always likes and that the documentaries always want is at one point they're like, well, can you put Scott in one of these and shoot him? And we're like, Okay. I mean, at that point, we'd done about a thousand test shots. I grew up shooting bows and arrows. I knew exactly how far that was going to go.
