Ancient galley rams discovered - photos

[Louie da fly]

 I found this on the Roman Army Talk forum on Facebook:

 

"Latest news from the maritime archaeologists working at the site of the Egadi Islands (Aegates Insulae) naval battle fought in 241 BC between the fleets of Carthage and Rome during the First Punic War.

Two new naval rams were recovered from the seabed at the Egadi Islands by the Soprintendenza del Mare, RPM Nautical Foundation, and The Society for Documentation of Submerged Sites divers. The total number of rams at the site is now 25. The raising of these rams highlights a successful, collaborative field season. Egadi rams 21 and 22 will be conserved and housed at the Ex Stabilimento Florio delle Tonnare di Favignana e Formica."

 

A post from another contributor - 

"Polybius (1.20.1-16) states that the Roman navy in the First Punic Wars consisted of quinqueremes abd triremes. The Carthaginian navy, which was far more experienced consisted of quadriremes and quinqueremes (though possibly with some triremes)."

 

 

 

 

These rams were hollow, as can be seen from the following two photos:

 

 

 

This would make sense - apart from the amount of bronze you'd need and the effect of all that weight up at the bow, otherwise how could you fix the ram to the ship so it wouldn't come off?

Fascinating!  That's going to leave a nasty mark when it hits the side of your ship!

You sir, are a master of understatement.

[druxey]

The size of the casting would have been a great technical achievement in its time.

From the site "The next step will be to cast a 1/4 scale bronze replica and, using digital load cells and stress indicators, ram it into various hull reconstructions and other bronze pieces at a crash test facility".

 

It'll be interesting to how much of a mark it leaves. Hopefully more than just a scratch in the paintwork!

[mtaylor]

Those tests will be interesting to see.  I'm curious how well things will scale down for these tests and do assume (bad idea, I know) they won't use glue on the test targets.

Ancient vessels were built "shell-first" - either without frames or with frames added after the planking was completed, and the planks were held together with tenons in mortises within adjoining planks, pinned in place with dowels.

 

(from https://en.wikipedia.org/wiki/Phoenician_joints )

 

According to Prof John Pryor's book Age of the Dromon the waterline ram was designed to break the tenons so the planks separated, letting the water in. Later (mediaeval) ships were built frame-first, and it is believed this structure was too strong for the waterline ram to have the same effect, and the "ram" moved upward to become a "spur", which it is proposed was intended either to capsize the enemy vessel or break its oars (or perhaps both).

 

I suppose the test model(s) will be constructed the first way.

Here's a link to a thesis by Asaf Oron of the Texas A&M Nautical Archaeology Program:

 

https://nautarch.tamu.edu/Theses/pdf-files/Oron-MA2001.pdf

 

The title is "The Athlit Ram: Classical and Hellenistic Bronze Casting Technology".

 

The thesis has pictures (page 84) showing how the Athlit ram might have been fitted to the bow of a trireme.

 

The rest of the thesis discussed how such a large hunk of bronze might have been cast in ancient times.

Really interesting idea. I hadn't thought of that connection. Thanks.

At the Battle of Hampton Roads, the CSS Virginia rammed and sunk the USS Congress, which certainly was built frame-first. Maybe the Virginia had so much momentum that neither frames nor tenons could withstand it.

Thanks for taking care of that.

Prof John Pryor's book Age of the Dromon

 

That's one big expensive book (aka a Tome). 

 

If anyone's is interested in the subject, Amazon have 2 paperback copies at $47 https://www.amazon.com/Age-Brills-Paperback-Collection-dp-900420590X/dp/900420590X. This is really cheap.

Well worth getting if you're into that kind of thing. Very well and comprehensively researched, and as far as I'm concerned though it was published back in 2006 is still the definitive work on the subject. The discoveries at Yenikapi in Istanbul have made some of it out of date, but it's still the best book out there on dromons.

Yes, much heavier and more powerful vessel than a galley, which was built as lightly as possible because it was moved by muscle-power.

I highly recommend the book, Gunpowder & Galleys by John F. Guilmartin.  This book covers galley warfare in the age of Lepanto. 

 

In this book, Guilmartin uses a value of 1/8th horsepower per rower.  This is based on hydrodynamic data developed by Admiral W.L. Rodgers USN in the 1930’s.  This would allow a Renascence Galley to be propelled at a speed of 7kts for a distance of about 3 miles.  After that, speed would decline rapidly.  The kinetic energy transferred to the target ramming, (I realize that by this time galleys did not ram) would be velocity squared x displacement x a constant to convert weight to mass and to account for the fact that the target would slide sideways when hit.

 

Although it might seem that damage from ramming could be increased by adding more rowers to increase velocity, this required a larger galley with more hydrodynamic drag to the point where a practical limit was reached.

Guilmartin, therefore makes the point that by the Sixteenth Century, a galley was primarily an infantry assault craft.

 

Jumping ahead to the Mid Nineteenth Century, steam propulsion completely changed the game.  USS Merrimack’s machinery was noticeably poor, propelling her at a speed  of between 5 and 7 knots on a good day.  Author Paul Silverstone claims a speed for CSS Virginia of 9kts which I find hard to believe.  Even at a slower speed her mass must have been an order of magnitude or more than that of a galley from any age.  Since basic wooden frame built ship structures had changed very little from the 1500’s she was during her short life a formidable weapon.

I've also seen a suggestion that ancient galleys didn't ram other vessels side-on, but on an angle from the stern. This makes sense if the opposing galley was travelling at speed - less likelihood of the ram being torn off by the collision. Unfortunately I've lost the reference.

 

[Edit] I read a book a while ago called (I think) The Crescent and the Cross - The Battle of Lepanto. It basically described the battle as one of a single round of gunfire, followed by soldiers boarding opposing galleys and wiping out the crews in hand-to-hand combat. The galleasses, being much slower (though much more heavily armed),  only figured in the battle at the very beginning after which they were left behind by the ebb and flow of the fighting.

 

And the battle had very little effect on the overall situation - the Ottoman fleet had been completely replaced within a year. It was more of a propaganda victory than a strategic one. [/Edit]

That’s a good book too and agrees with Guilmartin’s contention that the heavy guns carried in the galleys’ bow were capable of only one shot before battle was joined at close range.

[Louie da fly]

I'm sure I've read somewhere that the "ram" on renaissance galleys (which by this time was right up at upper deck level)

 

 

was used as a boarding bridge.

Some more photos of rams from the Egadi finds.

 

 

Apparently 26 of these have been found so far, along with helmet cheekpieces, coins and a sword . . .

Where is Egdi?

[Louie da fly]

That's the modern name. The Ancient name was the Aegates. See https://en.wikipedia.org/wiki/Battle_of_the_Aegates

I believe it was off the west coast of Sicily
