Cursing the emperor

July 31st, 2007 by sam moorhead

Early this year, a metal detectorist called Tom Redmayne was searching in a muddy field in the parish of Fulstow in Lincolnshire. He had already found Roman pottery (Samian ware from Gaul), some late Roman coins and several lead weights. Then he found several pieces pieces of lead, two of which were folded over.When he carefully unfolded them, he saw that they had holes drilled in them. Furthermore, in the centre of each was an impression. He took them to Adam Daubney, the Portable Antiquities Scheme Finds Liaison Officer for Lincolnshire, who realised that they were coin impressions.The curse tablet

Adam brought the pieces down to the British Museum where he and I established that the impressions were caused by bronze coins of the Emperor Valens that had been hammered into the lead. The pieces were then folded over and the edges of the sheets pierced. This was probably so they could be hung up. So how do we interpret this?

In the reigns of the joint-emperors Valentinian I (364–75 AD) and Valens (364–78 AD), the Roman historian Ammianus Marcellinus tells us that a certain Valentinus:

who was a native of Valeria in Pannonia [Hungary], a proud man, had been exiled to Britain for a serious offence. Like some dangerous animal he could not stay quiet; he pushed ahead with his destructive, revolutionary plans nourishing an especial loathing for Theodosius [a general of Valentian and Valens sent to Britain].

The same scholar reports that this troublemaker Valentinus started a rebellion which was quashed. He then describes the catastrophic events in Britain, commonly called the ‘Great Barbarian Conspiracy’, when Saxons, Picts and Scots (from Ireland) all ravaged the Roman province. Britannia was saved only by the swift actions of General Theodosius.

Modern historians have tended to overlook the revolt of Valentinus. But it has been suggested that this was the catalyst for subsequent invasions, as the
barbarians sensed that Britain was in turmoil and therefore particularly vulnerable to attack. It might be that during the revolt of Valentinus, one of his
followers decided to curse the emperors. It was traditional to write curse messages on tablets which were rolled up or nailed to a temple wall (you can see Roman curse tablets from Uley in the Roman Britain Gallery; Room 49).

In the case of the find, it seems that instead of writing the emperors’ names, a coin with a picture of the emperor was used instead. Then the lead was folded over and the pieces possibly nailed to, or hung from, a wall.At a later date, the two pieces might have been ritually deposited, possibly in the ground. This is only my personal interpretation – we will never know for certain why they were made, but perhaps they were created by a follower of the rebellious Valentinus. Whatever the truth, we have not found other objects like these in Britain.

The curse tablet is recorded as database record: LIN-57B091

Mush! Sphere of influence using CCI data

July 30th, 2007 by daniel pett

Last week, Sean Gillies, the lead developer for the Pleiades project at University of North Caroline blogged about his experimentation with an application he is building called Mush. He’s taken 2 georss feeds and has combined them using a PULL method to determine the sphere of influence. He writes more about this at Import Cartography and specifically uses information drawn from the Celtic Coin Index to represent his example. Fantastic and just what I wanted people to start doing with the data that I’ve bent.

As Tom Elliot put it very eloquently in his email to the Pleiades project mailing list:

Sean’s demo application takes

(1) an XML webfeed (a query result, in fact) from http://www.planningalerts.com (a site that searches “as many local authority planning websites as it can find” in the UK and provides details of development applications in user-specified locales)

and (2) a separate XML webfeed from the Oxford Celtic Coin Index (via the Portable Antiquities Scheme; kudos to Dan for implementing that feed as part of the coin index’s API!)

It then parses each for georss tags (i.e., encoded spatial information), then puts 1km radius buffers around each encoded point and then looks for intersections between any of those circles. The resulting intersections are provided as another, new feed, which can also be pumped directly into an online mapping tool (in this example, Sean runs it through google maps).

Result: a visualization (or shareable information) about development applications affecting areas where Celtic coins are known to have been found.

The method, of course, is extensible to almost any combination of feeds that have geo information in them.

Imagine what could do automatically and on-the-fly with similar calculations on 1km bubbles around pleiades places and similar bubbles
around:

* epigraphic findspots GPS-gathered by the Inscriptions of Roman Cyrenaica Project

* footprint records for archaeology survey projects and datasets cataloged by CGMA/MAGIS or archived/served by ADS or OpenContext

I thought that Sean’s work needed more publication over here. Good work that man. There will be loads more to come from him without a doubt.

Roman coins ID pages updated

July 30th, 2007 by daniel pett

PertinaxOver the last few days, I have been adding to the Roman coins pages. Ian Leins has had a splendid volunteer (Natalia Bauer) who has scanned some rather nice images of the 3rd Century AD Roman Emperors and I’ve now incorporated these into our most popular resource, the Roman coins guide.

I’ve also adapted the content slightly and you can now see the following information on the Emperor’s details page:

  1. Mints coins issued from
  2. An example of their coin obverse
  3. Some have biographies – these will be completed shortly
  4. Last 10 coins recorded on the Scheme’s database
  5. Their Reece period
  6. Denominations issued
  7. A breakdown of coins recorded by county

I’ll add zooming images of the Emperors’ obverses when I get to a less locked down computer (BM IT has blocked that…) The relational tables that show how the rulers relate to mints,denominations,reece period are attached at the foot of this post. Feel free to use them.

The coin guide will be enhanced more as time goes by with a picture of the Emperor’s bust and some information about British sites. When I get the database sorted out to pump out KML on demand, you’ll also be able to plot the recorded coins (obfuscated accuracy) onto a google map embedded on the page. Anyone got other ideas of what they would like to see?

My last wish is that the Government will pledge….

July 27th, 2007 by daniel pett

House of Lords logoThe TWFY feed alerted us to a section of Lord Howarth’s speech in the House of Lords debate on “Government: Draft Legislative Programme” yesterday. Lord Howarth said:

My last wish is that the Government will pledge themselves to sustain the portable antiquities scheme. This is a voluntary scheme for recording archaeological finds that are made by non-archaeologists. The aim is to enable the information contained in these finds to be recorded and to illuminate our national history and local understanding. Noble Lords will have read recently of the extraordinary find by metal detectorists of a hoard of Viking treasure in north Yorkshire. Before we had the portable antiquities scheme, finds were largely not reported or recorded, and many simply disappeared. The scheme has been hugely successful. Sixty thousand reports of archaeological finds are made by members of the public every year, and a great many children and others attend educational events and workshops under the scheme. It is terrific value for money. The money needed in the next year is only £1.65 million. That is affordable, but it would be vulnerable if we were to have a less than generous spending outcome for the DCMS.

I’m quite pleased with the mining of the Parliamentary data, it shows how useful it is! And just to update this, David Dawson from MLA alerted me to the top searches on TWFY, see the image below!

National Archaeology Week statistics

July 27th, 2007 by daniel pett

Last week was National Archaeology Week, co-ordinated by the Council for British Archaeology. The Scheme ran a wide variety of events and talks which reached a grand total of 6919 people with nearly 45% being children. The spreadsheet found below records how many people attended each event, the number of objects offered up for recording and the number of records actually recorded.

We also have a set of photos on Flickr that shows what everyone got upto – enjoy!

Finds from the Frontier

July 26th, 2007 by daniel pett

This conference might interest some of our readers. Our very own Rob Collins seems to be heavily involved with this, back to your day job Dwarf King! Finds conference logoFinds from the Frontier is a conference that aims to bring together finds specialists of the Roman period with the specific aim of shedding light on the lives of the 4th century limitanei of Britain . This late period is generally seen as one of declining standards in the Roman military and materially poorer than the previous centuries. Do the artefacts that were left behind justify this stance?

While individual papers are focused on individual classes of artefacts, this conference will not simply provide papers offering typologies for 4th–5th century material culture. Rather, the primary emphasis of the conference is to provide interpretations of the life of the late military community (soldiers and ‘civilians’) through artefactual evidence. What do the finds tell us about frontier life in terms of eating, personal appearance, economy, and identity?

At present, the following have agreed to speak on these topics, with other papers and speakers to be confirmed in the near future:

The 4th Century Frontier Tony Wilmott

Coins Richard Brickstock

Personal Appearance Lindsay Allason-Jones

Epigraphy and Written Sources Mark Hassall

Environmental Evidence Jacquie Huntley

Brooches Rob Collins

‘Barbarians’ North of the Wall Fraser Hunter

Identity Hilary Cool

50,000 objects recorded for 2007

July 26th, 2007 by daniel pett

Since the 1st January, the Scheme has recorded 50,000 objects offered to our staff and volunteer recorders for the benefit of archaeological researchers, planning offices and other interested parties. In the previous year, we recorded 56,438 in the 12 month period beginning Jan 1st 2006 and ending on New Year’s Eve. So we’re on course for a record year of object information being made available. Some of the objects recorded this year have brought some interesting publicity to the fore – for example the Harrogate Hoard, Adam’s work on Tot rings and the slave figurine to name but a few. There’s no doubt some more interesting stories to tell as the year unfolds.

Objects

The graph above shows the increases, and the last year is only partial so shows a dip so far. By year end this will be a lot higher. Obviously these stats are quite emotive and will cause comments about archaeological record erosion, but these arguments will always linger.

For those that don’t know, the Scheme is also going to be 10 years old in September and there should be some special publicity to mark the occasion.

PAS flickr feed made public

July 25th, 2007 by daniel pett

We used to have a very active photo gallery based on the opensource gallery software; however this seemed to suffer from a variety of archiving robots that caused the site to seize up regularly. To combat this, I’ve decided to move our photo system across to flickr and see if we can get some user driven content onto the site relating to events and meetings run by the Scheme. Our id is “portable antiquities” and you can access these photos directly under an “attribution” Creative Commons Licence. If you want to get an RSS feed of these, you can also do this.

The Scheme’s homepage now features a feed of images directly from the flickr site and updates automatically and uses the class wrapper provided by phpflickr to compile the images on screen. The code is below and also makes use of caching to speed up the rendering of the images.

enableCache(
    "db",
    "mysql://userid:password@server/database"
);$i = 0;
 {
    // Find the NSID of the username inputted via the form
    $person = $f->people_findByUsername('flickr username');

    // Get the friendly URL of the user's photos
    $photos_url = $f->urls_getUserPhotos($person['id']);

    // Get the user's first 15 public photos
    $photos = $f->people_getPublicPhotos($person['id'], NULL, 15);

    // Loop through the photos and output the HTML
    foreach ((array)$photos['photo'] as $photo) {
        echo "<a href="$photos_url$photo[id]">";
        echo "<img alt='$photo[title]'>buildPhotoURL($photo, "Square") . "&gt;";
        echo "</a>";
        $i++;
        // If it reaches the third photo, insert a line break
        if ($i % 3 == 0) {
            echo "<br />\n";
        }
    }
}
?&gt;

You can adapt the script quite easily to your own needs, or go for different flavours of output such as JSON – I’ve used that on another site. If you want to add photos to flickr that relate to the Scheme, perhaps use the tag “portable antiquities” and I’ll set up a feed of user driven content on the site. I’m thinking about setting up a page that draws in content from technorati, del.icio.us, digg, They work for you and various other sources that aggregates comments relating to the Scheme.

PAS and oral questions

July 24th, 2007 by daniel pett

The Scheme was mentioned in “Oral Answers to Questions — Culture, Media and Sport” relating to the Renaissance in the Regions programme yesterday. Frances McIntosh, our FLO for Cheshire and Greater Manchester was mentioned by her local MP who had visited her National Archaeology Week event. The exchange bewteen Brian Iddon and James Purnell can be viewed on the They Work for You page that turned up via the RSS feed I built from their getHansard XML feed last week. Success!

Revamped section and new feature

July 24th, 2007 by daniel pett

Over the last couple of days, I have been revamping one of the resources I built with our old Roman Coins Finds Adviser Ian Leins. He has since moved on to become a Curator within Coins and Medals in the British Museum with responsibility for Iron Age coins and their study and interpretation. Since then, Sam Moorhead has come into his role and we’ve revamped the Scheme’s database numismatics substantially. I’ve used the basis of this work to complete some major additions to the facilities we have for the identification of Roman coins. So this week, I have added:

  1. Google map with KML layer for Roman Mints (shown below)
  2. Added a Reece periodisation guide
  3. Enhanced the mint information to demonstrate under which Emperor these issuing places were active
  4. Enhanced the emperor information pages so that you can now see what denominations they issued, which Reece period they fit into, mints active, most recently recorded coins by our staff, and a county breakdown
  5. Tidied up the high resolution pages that make use of the free zoomify viewer (I’d forgotten to add the Google code to these pages!!)
Center of map
Roman mints
Roman mints map

To come within this section:

  1. Enhanced biographical data
  2. Thumbnail images of most recently recorded coins
  3. Scrolling image carousel to aid identifications
  4. Later Roman emperors
  5. Check the code for validity

This section is far and away our most popular area of our site. Google Analytics, shows that the average weekly traffic to our website is 10-15% of our total and visitors look at over 30 pages and have an average visit length of 15 minutes. It’s now the top ranked tool for coin identification on Google.

In terms of new features, I’ve added Google’s Cooperative search to our site. It seems to work quite well and indexes the following sites (seems to be quite comprehensive):

  1. finds.org.uk
  2. pastexplorers.org.uk
  3. findsdatabase.org.uk
