Thanks Dave! Hopefully I was convincing. I wanted to leave it open to add further information or a different interpretation as well.

If they exist, I’ll find them! Three-bladed waterline rams and ancient warship-inspired monuments at Union Station in DC. Though these are some pretty odd ones…

Thanks for reading it! I might be wrong, I might be right, but I think it’s something worth looking at and exploring further, especially now that we have so much more information about naval rams.

Finally got to visit my sister’s workplace at the NIH! The work they’re doing there is incredibly important, and it was really cool to see some of it firsthand. A great reminder of why effective and continued government funding for research matters so much.

Revisiting the Isis Sgraffito: Evidence for a Cimmerian Bosporus Naval Ram Design

The article reexamines the Isis sgraffito, arguing that we may be looking at a local Cimmerian Bosporan warship rather than a Ptolemaic vessel, with a distinctive regional naval ram design. Another small piece of the ancient naval warfare puzzle!

Rainy day….working in the office on the Syracusan trireme modifications of 413 BCE. I’ll finish this paper (eventually), but today I’m really missing Actium. All this bad weather has me thinking about those rainy/cloudy days spent scanning the monument.

Excited to see my chapter, “Odysseus’ Naval Ram?”, published in Iconography of War in the Ancient Mediterranean World! Many thanks to the editors, Julio C. Ruiz and Marta Nicolás-Muelas. It’s great to see a conference group come together and turn our papers into a published volume!

It looks like William Murray and I are moving forward with a monograph on the 27 ancient naval rams discovered at the Battle of the Egadi Islands (241 BCE), to be published by Texas A&M University Press. We’re excited to be working with our colleagues in Europe and the USA on this project!

Already spotting ancient warships in Yale’s architecture! This one is at the entrance to Sterling Memorial Library. Phoenician ship inspired? Straight from the Kouyunjik relief?

It’s a fancy drinking vessel in the shape of a warship and with what may be a boar’s head naval ram. Very odd looking overall though!

There’s a similar dinos at the Getty Villa (92.AE.88) with a battle on top of the rim, and four warships on the inside of the rim. The ships would have appeared to float on the mixed water and wine when the vessel was full. Greek, Athens, 520-510 BCE, Circle of Antimenes Painter.

Stephen DeCasien, Ph.D. @sdecasien.bsky.social · 07/08/2026
I love all of these depictions of ships on the rim. It’s surprising how many examples exist. I suppose people really liked the image of ships splashing through the wine-dark sea 😅!

A fragmentary stele depicting an ancient warship with a three-bladed waterline ram at the Boston Museum of Fine Arts, # 1987.297. Nice to finally see this one in person!

Actually the 12th Egadi ram (Roman example) recovered had almost this exact composition!

This one is just part of a fancy funerary monument! Actual naval rams used on ancient warships were all bronze.

Stephen DeCasien, Ph.D. @sdecasien.bsky.social · 17/07/2026
There was probably a matching ram, but it’s been lost to time. The surviving piece preserves incredible detail and is one of the few with a carved animal head on the cowl. Early publications identify it as a lion, but the pointed ears look much more like the wolf heads depicted on ancient warships.

Four years ago today! Nearly 100°F, not a cloud in the sky, and I spent the day searching all over Ostia for this stone ram. Of course, it turned out to be tucked away in a back corner. This was during the AAR Classical Summer School, and it was definitely worth the hunt.

Proof day! 🏺⚔️🌊 Just received the proofs for my upcoming chapter on Odysseus and the Sirens. It explores how ancient artists adapted the myth to reflect the naval warfare of their time, helping us understand the development of bronze warship rams. Almost perfect timing for Nolan’s The Odyssey!

Stephen DeCasien, Ph.D. @sdecasien.bsky.social · 09/07/2026
Yay! Just accepted in IJNA! ⚔️ 🌊 I argue that Murray (2001/2002) was right that the ram is small and likely belongs to a trireme, but that its design is better understood through the Cimmerian Bosporus rather than the Ptolemaic or wider Mediterranean world.

Stephen DeCasien, Ph.D. @sdecasien.bsky.social · 09/07/2026
If the rams do indeed come from quinquereme warships then maybe around 300 to 400 per ship (numbers vary by ancient authors and modern reconstructions). A horrific scene no doubt for all involved, especially the Carthaginians.

When the ROV hit the bottom and the cameras came on, there it was… a new ram. E27. That moment where instinct, a lot of luck, and a whole team’s effort all collide is hard to beat. I’ll never forget that moment!

What’s your favorite day in the field doing archaeology? Mine goes back to the Egadi Islands survey work for RPM Nautical. It was my first time out there and planning/picking the underwater targets for the day. I went with this small shadow on the sonar, well away from the main cluster of rams.

Stephen DeCasien, Ph.D. @sdecasien.bsky.social · 06/07/2026
Second: House of the Dragon shows an odd three-pronged ram style prow, more like later Byzantine inspired ship design. Ramming does happen, but too much damage for that type of ram. 3/10.

This week in naval rams in popular culture! First: Rick and Morty goes with a kind of three-bladed waterline ram on a single level galley, reads Egyptian/Levant inspired in overall shape and iconography, but pushed hard into sci-fi exaggeration. No ramming though! 6/10.

The largest bronze fragment recovered near the rostral wall of the Actian Victory Monument. Among the few surviving relics of the Battle of Actium (31 BCE), it may have originated from one of the massive warships that served in the fleets of Antony and Cleopatra.

Hmmm I thought in the permanent? I might be mistaken though. 🤔. You’d know better than me! That motif is notorious for having very odd naval rams (especially for Etruscan depictions).

Love it! I wonder if you ran into any sarcophagi with the Odyssey and Sirens motif?! I think there was one floating around there.

The funny thing is the professor never changed anything. Years later I still get emails from grad students asking for my study guides, and I never send them to just one person. If I’m sharing them, I send them to the whole new grad class. That’s my way of helping students beat that shitty system.
120
Stephen DeCasien, Ph.D. @sdecasien.bsky.social · 07/06/2026
Funded students often had more time to study while others had to work, so the system favored those with the most free time. The sad part is that if we'd studied together, we all could have done better, but some students saw grad school as a competition rather than a collaborative learning experience
