The four surviving stones at Waun Mawn are of unspotted dolerite, and possibly derive from outcrops 3km to the south-east at Cerrigmarchogion on the Preseli ridge (Bevinset al.2014). 1

Synopsis with dating of Waun Mawn stone circle.
Source
As some of these samples could also have been either residual or intrusive, we propose that the stone circle was erected inc. 3600–3000 cal BC. This date would place Waun Mawn amongst the earliest stone circles in Britain, alongside Long Meg and her Daughters in Cumbria (109m diameter) and the stone circle beneath the passage tomb of Bryn Celli Ddu on Anglesey (18m diameter). 1

Look up this process and evaluate the mechanism for how it works.
It essentially allows dating of samples based on when they were last exposed to sunlight.

To resolve this, radiocarbon dating of these samples from Waun Mawn was conducted in conjunction with optically stimulated luminescence (OSL)dating of sediment from within the packing deposits that were contemporaneous with the monoliths’ erection, and from filled-in sockets (from after the monoliths’ removal). OSL dating determines the burial age of sediments, with the dating signals being reset by light exposure immediately prior to deposition (Smedley2018). 1

“I’m not a musician. I don’t mean that in a derogatory way. But I mean, I wasted a lot of my life playing instruments, which was foolish,” O’Rourke told the newsletter Tone Glow in an interview published in May 2020. “I have no interest in anything being a vessel for expressing something . . . I always like to say, ‘I do stuff.’ ” 1

Almost every anthropology source I’ve read in the last six months has highlighted some version of this:
If our short history of experience with archaeology is any indicator, it can be very dangerous (and painfully wrong) for us to transfer our customs and beliefs onto other cultures and civilizations which don’t have our culture or knowledge base.
However we can more easily transfer broad generalizations from and across various cultures when we discuss how humans used memory and orality (within their cultures) particularly when they would never have interacted with each other.

We cannot transfer beliefs or customs from one culture to another, but we can transfer generalisations from multiple cultures about how humans maintain critical knowledge when they are dependent on memory. 1

Being welcoming and inviting can be an important thing. If you’re not, then your material is not even considered.

Terry is concerned by those commonly cited statistics revealing how little time museumgoers spend looking at art, but more upsetting is that most people don’t feel welcome in museums at all. “They’re looking for zero seconds,” he says. 1
