Oxfordshire museum purchases iron age hoard after fundraiser Friends of the Oxfordshire Museum has brought the hoard which includes a 2,000-year-old horse brooch.

"...as the threat of a public sale loomed."

AKA the finder/landowner ransomed our shared heritage until we coughed up. ๐Ÿ˜ก

Again, and again, and again, and again... it's relentless.

Why would you name "rock dwellings" (actually 3D-printed concrete blocks) Navajoo and Hoodoo?

One a Native American Nation that do not build rock dwellings; the other a set of African American spiritual practices.

Why build "rock dwellings" in the flattest country on earth in the first place?

Er gaat een oproep rond om veel en massaal naar Vrijheid, Gelijkheid, Zusterschap van Sophie Straat op Spotify te luisteren. Als protest dat een anti-AZC nummer (gegenereerd door AI) op 1 gaat komen en dat willen we niet.

Wij zijn met meer. Doen jullie mee?

The actual number doesn't matter anyway, as most Americans would never even get close a single dime of these investments.

Vakbonden: 9 december demonstratie tegen โ€˜sloopโ€™ hoger onderwijs Er komt opnieuw een actie tegen de bezuinigingen op het hoger onderwijs op 9 december.

Terwijl het deze campagne nauwelijks gaat over onderwijs, stemde vandaag een rechtse meerderheid in de Eerste Kamer in met nieuwe bezuinigingen.

Weer met hulp van het CDA.

Hopelijk neemt iedereen met hart voor onderwijs of opgroeiende kinderen, dit mee in het stemhokje.

Doe. Het. Niet.

Bezuinig niet op het onderwijs! ๐ŸŸฅ

Vandaag maakt het CDA in de Eerste Kamer wรฉรฉr dezelfde fout als eerder dit jaar door de bezuinigingen van de VVD aan een meerderheid te helpen..

Stem morgen op een partij die het onderwijs niet laat vallen! ๐Ÿ”ด๐ŸŸข

I do wonder which is more effective:

Our policy of appeasement? (which does not (or not fully) combat illegal detecting anyway (attached photo of recent example I came across)

Vs. a policy that would require perhaps more enforcement, but also makes the enforcint easier, like the Swiss one.

28.10.2025 08:50 โ€” ๐Ÿ‘ 3    ๐Ÿ” 0    ๐Ÿ’ฌ 1    ๐Ÿ“Œ 0

Still, I represent a minority view and most colleagues are mostly afraid of driving detecting underground and really (and rightly) value the fact that at least there is communication between (parts of) the detecting community and the archaeological field.

So, it could actually increase value of registered finds on the market, which makes being a FLO in the Dutch version to my mind ethically problematic (it clashes with EAA code of conduct).

What is worse (I think) is that the portable antiquities scheme can be regarded as a sort of certificate of authenticity.

A few years ago, I spotted some celtic staters from Holland on eBay where the description included the determination of kind and age by a professor from the scheme.

In Belgium apparently, there is a kind of licensing scheme, so you can only own a detector and use it when registered. This might at least help in keeping track of who is detecting and might help with law enforcement in the case of heritage crime.

I feel detecting is a tragedy of the commons. Communal heritage is exploited for leisure and sometimes for cash.

And what would be communal property if discovered through building work or excavation becomes individually owned at the ping of a detector.

I have the same worries in Holland. We have a Portable Antiquities Scheme modelled on the UK one, but no treasure act.

Finders are required to register (not all do), and keep finds available for research for 6 months. After that, they can sell (and museums must acquire) on the open market.

Acht jaar geleden postte Wilders al ophitsende nepfoto's op social media. Het enige verschil met nu is dat de PVV nu zo groot is dat hij anderen in de fractie kan vragen dit te doen. Wilders' excuses zijn waardeloos.

3). Unsure. Podcasts are too slow and boring to pay undivided attention to, but in order to follow them, you do have to pay attention, so they do not combine well with many other activities, except perhaps doing the dishes, but then wearing headphones in the house just seems silly.

1). Hardly. I prefer to read, as it is much quicker.
2). The rest is history (sometimes, could count as partially archaeology). This is literally the only podcast I occasionally listen to. I do not find the format very appealing.

45k people calling on our politicians to pay attention to the biggest issue of our times: Climate change, which gets zero attention in the current Dutch elections.

Bijzonder onderwijs werkt discriminatie in de hand (zie B-bal over LGBTQ en vrijheid van onderwijs).

Daarnaast is bij mij in de stad een sterke correlatie tussen privilege en kinderen op bijzonder onderwijs. Het werkt dus ook kansenongelijkheid in de hand.

Beide zaken zou ik graag anders zien :)

Ik kan me idd niet vinden in het racisme. Maar ik vind art 23 ook problematisch (zie daarvoor de uitspraken van B-bal onlangs over hoe religieus onderwijs best mag botsen met art. 1).

De grondwet veranderen is niet per se problematisch. Om bijv. een correctief referendum in te voeren, of om de monarchie af te schaffen moet dat ook.

Dat zijn imo hele redelijke voorstellen.

No beforore Homo, concurrent with Homo.

To my knowledge, the oldest Homo sp. fossil (Ledi Geraru) is the same age or slightly older than P. aethiopicus (the oldest Paranthropine).
