A 13th Century guide to the heavens

Jennifer Evans, 5 June 2013

Ioannis de Sacro Bosco [c. 1195 –c. 1256] was a scholar, monk and astronomer [probably English] who taught at the University in Paris. In around 1230 he wrote this authoritative medieval astronomy text Tractatus de Sphaera [On the Sphere of the World]. It gives a readable account of the Ptolemaic universe[the universe according to the Hellenistic astronomer Claudius Ptolemaeus in the 2ndcentury AD] that went on to become required reading by students in all Western European universities for the next four centuries. Though principally about the heavens it contains a clear description of the earth as a sphere and its popularity shows the nineteenth-century opinion that medieval scholars after this date thought the Earth was flat as a fabrication [Wikipedia].

This copy [photographed here] is dated 1577 and forms part of our Vaynor Collection; this consists of a number of 16th and 17th century astronomical works, including several of the writings of Galileo. The collection was formed and donated by John Herbert James of Vaynor [which is just north of Merthyr Tydfil].

The condition of this book is excellent; the paper is bright and unmarked, robust to the touch and all the little volvelles [rotating paper wheel charts] still work perfectly.

It is bound in pure white vellum [calf skin] as are the majority of the Vaynor astronomical books which I always think gives them a very "celestial" look.

Peregrines on the Clock Tower 2013

Peter Howlett, 29 May 2013

May 29 update

Well the chicks are now about a month old and the change in the last 10 days or so has been dramatic. The pictures show them at about 20 days and then a mere 8 days later, changing from fluffy white balls to something resembling a Peregrine.

If all 3 chicks fledge - possibly a big if given the knack they have of falling off the tower before they can fly properly - this will be a very good year. Well, I suppose it is anyway as the adults wil have raised 3 chicks to fledging age, just that the nest site isn't particularly safe for youngsters!

Judging by the size of the young it looks like there may be one female and 2 males. At one month the difference in size between the sexes is apparent even from a distance.

The next 2-3 weeks will be very challenging for the youngsters, I hope they manage to stay on the tower!

May 3 update

Plenty of feeding taking place today and I think there may now be 3 chicks. Their heads are becoming more visible by the day so it should soon be very obvious how many chicks there are. Female seems to be doing most of the feeding at the moment with the male bringing in the food.

I hope the chicks are more sensible this year when they are bigger and don't get too adventurous too soon - the ledge by the nest isn't very wide! 

Watch their progress here

Falkland Islands 2013: February 4th update

Peter Howlett, 5 February 2013

04.02.13
I ended up sampling two different shores at Hill Cove, one below the main settlement and the other at the far east end of Byron Sound by the West Lagoons area (Photo 1). Each was slightly different although fairly low in diversity with clean fine sand. In between those I also went to Shallow Bay (Photo 2) which was further east and north and very rocky. Here I found some interesting worms that I don’t think I had seen elsewhere under the rocks and in crevices. As the tides have been getting later the morning tides have been gradually creeping towards more viable times themselves. The second shore in Hill Cove was actually visited very early in the morning although I must admit my dedication to getting up before breakfast nearly waned when I heard rain lashing against the window. Luckily that passed and I did make it out.

Saturday morning dawned bright and still and the tide was slightly more sociable at 9am and, being a 5 minute walk down the hill, did not require too early a start. This was Port Howard where we were due to get the ferry back to the east in the afternoon, so a last easy site was a good way to finish. By mid-morning the wind had picked up and by lunchtime I had a feeling the ferry ride might be a little ‘lumpy’ but so long as we got back across the sound I didn’t care. Commerson’s Dolphins saw us off, playing in the waves alongside the ferry, a nice farewell (Photo 3). The trip was indeed lumpy but less than 2 hours later we were back in New Haven and after another 2 hours were in a very wet and blowy Stanley. Photo 4 shows the locations of the sampling sites.

The tour around West Falkland has been very successful with a range of different sites visited from all a around the coastline and I have collected some very good samples. Highlights that stand out were the large lugworms at Port Stephens (Photo 5) and the densely packed onuphidae colonies that occur in patches on many of the sandy shores (Photo 6). I have also seen many animals that I am sure I did not collect on the previous trip so that bodes well for the final species list.

Back at the office I set to finishing packing the precious samples. I had been regularly keeping up with changing the fluids in the pots while I was travelling and even sealing them up and putting them into small bags ready so as to make the packing process quicker. In no time at all I had 6 boxes packed and taped up. This was more than I had been expecting to have considering I have already sent 3 boxes back and I didn’t think the lady in the post office would be very happy to see me! Certainly I don’t think I gave her a good start to a Monday morning.

With my flight early tomorrow morning I only have today left here to wrap everything up. I’ve visited 23 different sites around both East and West Falkland over the last four weeks and after this second trip my map of sites looks much more comprehensive with points all around the coastline. Hopefully the eventual species list, together with a voucher collection that will be returned to the islands, that will come out of the project will enable future researchers out here to make better and more accurate identifications of this important group.

I have a radio interview this afternoon with the local station to talk about the research I am doing so that will be a good opportunity to explain to more people the purpose behind the visit.

So it just remains for me thank all of the islanders out here for their help, support and cups of tea during the trip (particularly those that helped and supported my car and supplied brake fluid).

The project also could not have continued without the support and assistance of the Shackleton Scholarship Fund and the Amgueddfa Cymru - National Museum Wales

Thank you all!

How more sales can mean less revenue

Mari Gordon, 1 February 2013

And they're here: for the first time, we have figures for a year of e-book sales, supplied directly by publishers. It's still far from the whole picture, as not all e-book figures are available. But we now have a much better idea of what the book-buying landscape looks like in the UK.

The figure that stands out is that e-book sales are now up to 13%-14% of all book sales. However, as their prices are cheaper, that's only 6%-7% of revenue. Print book sales are down again, by 3.4% on 2011, as are average prices.

The e-book market is still dominated by fiction, and those e-book figures track the print figures. That is, if a book sells well in print, it also does well in e-book. The stand-out example is a particularly, shall we say, shady trilogy, whose e-book sales are about 36% of the print sales. Could the success of the e-book version of these titles lie, I wonder, in the fact that no-one can see what you're reading on your Kindle...?

So, it's mixed news: more books were bought in 2012, but because more of them were e-books, publishers made less money. Good news for reading, less so for publishing.

Meanwhile, here at Amgueddfa Cymru our journey into 'e' continues...

 

With thanks to The Bookseller for the sales figures.
