Today began with a presentation by Erni Pelham relating to her research project. This was an interesting interlude, outlining key facts and findings, providing me with tips for my final presentation.
A PHARYNGEAL BONE FROM A BALLAN WRASSE FISH
My research journey began during a visit to the museum stores, where I noticed a photocopied image on the wall behind Gary Edwards desk which captured my attention. My object was staring me in the face, I found the object visually appealing, and at first glance I thought it was a piece of jewellery, a pendant encrusted with pearls, how wrong I was!
I had no idea of the scale of the object, the image was secondary, making it difficult for me to guage it's actual size. Object measurements: 4 cm long x 2 cm deep x 1 cm thick.
Within the stores on a shelf was a box of small transparent bags containing artefacts, my object was amongst this collection. I was offered the opportunity to handle it for the first time, becoming my primary source. Surprised at how small it was compared to the image, I wanted to find out more about this fascinating object.
My curiosity soon took over, formulating questions to begin my research process; What is it? - How old is it? - Where was it found? - Who found it? The secondary source information that I received, led me to it's place of discovery, the Foundry in Poole, and my primary source, David (Dai) Watkins, site archeologist, and author of a book "The Foundry - Excavations on Poole Waterfront 1986/87", this was an excellent starting point for my research.
Initially, I referenced maps of Poole to locate the Foundry site which was supported by Katie Heaton, a secondary source for my research. It became apparent that the information I was looking for was in David's book; back to my primary source.
The bone is context pit feature 269 of 443 fish bone fragments discovered. Dating the object was determined from the dig stratum data (C - G) showing periodic layers from the site, then analyzing the fragments and artefacts to determine dates.
The recorded data indicates 1405 - 1780.
I proceeded to use my secondary sources to gather further information about the object, and in particular the Ballan Wrasse (Labrus bergylta) - 'Bollan' (Manx Gaelic), to identify the bone and it's function. A Pharyngeal bone containing teeth located at the back of the throat and part of the upper palete, to grind Crustations and Molluscs, after using it's sucker like mouth with large frontal teeth to consume it's staple diet from rocky coastal locations, it's natural habitat.
The size of the fish is approximate evidenced by secondary sources (records from known landed Ballan Wrasse in the Uk) : Weight 10 - 11 lbs (4.5 - 5 kgs) - Length 50 - 60 cm.
The 'Bollan Cross' with it's triangular shape was seen as representing the cross, so the Pharyngeal bone became known as a 'Crosh Bollan' in Manx, "A charm or good luck token (talisman) traditionally carried by sailors", although there is no evidence to support this.
The BC can also be found on stamps from the Isle of Man circa. 1981.
