Francesca’s Bookshelf: The Common Muse: An Anthology of Popular British Ballad Poetry XVth – XXth Centuries

You may remember from my earlier blog posts that Francesca loves to collect old books of ballads and songs. In fact, with all the necessities of life taken care of, and book collecting as her only real hobby, it’s all she has to spend her allowance on. It’s unsurprising that her collection contains numerous old and very interesting books.

Today, Francesca is browsing The Common Muse: An Anthology of Popular British Ballad Poetry XVth – XXth Centuries. Edited by V. de Sola Pinto & A.E. Rodway. This first edition was published by Chatto & Windus, London in 1957. The objective of the editors was given on the front flyleaf of the dustjacket. The dustjacket is missing from many copies of this book, so I have reproduced the editors’ objectives below for you (click to enlarge it). From this, you would expect the book to contain a wealth of old popular poetry, songs and ballads, and you would not be disappointed.

There is a 29-page introduction, which begins with the words: ‘Though many of our greatest poets knew, used and imitated street songs and ballads, in modern times it is mainly the political and social historians and antiquaries who have so far paid serious attention to them. Literary critics and historians dismiss them as “doggerel” or “journalism in verse”. What was good enough for Shakespeare, apparently, is no longer good enough for us.’


The introduction goes on to give a critical analysis of the genre of songs and ballads in poetry from mediaeval times to the 20th century. The authors discuss varying perceptions of the literary and moral value of these works, at the same time highlighting the wide range of subject and style, from bawdy to romantic, from historical to social commentary. They acknowledge that while the preservation of mediaeval verse can be attributed to broadsheet1 publications, they also owe a debt to ‘folk memory’, since the earliest songs and ballads were composed and sung by minstrels, many of them itinerant, and passed on by word of mouth rather than printing. The critical analysis is an engaging read for anyone with an interest in this kind of poetry.

Following the introduction, the book is structured in two parts. Part I: General has subsections Historical; Social Criticism; Manners and Fashions; Soldiers, Sailors, Highwaymen and Poachers; Portents and Prodigies; Crime and Punishment; Religion. Part II: Amatory has subsections Rural; Urban; Vocational; Clerical; Marital; Wise and Foolish Virgins. As is apparent, this collection contains a rich variety of interesting songs and ballads. Each subsection is prefaced by a delightful woodblock print, and contains a number of songs or ballads.



After browsing for a while, Francesca finds herself reading a song called Don’t Be Foolish Pray.

Young Hodge met Mog the miller’s maid
Who long his suite denied,
And half inclined and half afraid,
Scratched his rough head and cried:-
‘Now Molly while I love you so,
Why still our joys delay,
Come dang it, to the parson go,
And don’t be foolish pray.’

Sweet Moggy with an artful blush
That sham’d the rose’s hue,
Looked round, and cried to Hodge ‘hush hush
Speak softly, softly do:
We shall be overheard I know,
The mill don’t work to day
Be quiet, Hodge my hand let go,
Now don’t be foolish pray.’

Poor Hodge, thus chid, at a stand,
And cried,-‘Well then, good bye,
I’se go to give to Sue my hand,
Since thee do cast off I.’
‘Me cast you off’, cries Moggy ‘no,
The mill don’t work to day;
And so dear Hodge, to church let’s go,
And don’t be foolish pray.’


Francesca rather likes the idea of a blush that shames the rose’s hue, but she’s not quite sure of the wisdom behind Molly’s initial refusal of Hodge’s hand. Perhaps Molly is toying with him. Would Francesca do such a thing herself? She doesn’t really want to have to answer that question.

The song was recorded by the brilliant folk-singer/guitarist Nic Jones on his album Ballads and Songs in 1970. If you’re not familiar with his work I highly recommend you get the album for this, and the other wonderful songs and ballads on it. As a tune for this song he used a part of the tune The Merry Merry Milkmaids from The Dancing Master by John Playford (published in a number of editions from 1651 to about 1728). He also altered the words a little to scan with the tune.

In the sleeve notes for Ballads and Songs, Nic Jones wrote, ‘The printed broadsides are often accused of stunting the growth of folksongs and of solidifying the words by submitting them to print. True as this is in many cases, they also created and diffused a great many songs which possess a deal of charm in themselves. Don’t you be foolish pray is a good example of this, probably created by a townsman with his idealised view of rural life. In many instances, songs such as this appealed very strongly to the country singers and were allotted high positions in their repertories.’

1: According to the Oxford English Dictionary, the words broadsheet and broadside both refer to a large sheet of paper printed on one side only. These were used to publish ballads and songs, as well as news items and advertisements, and sold by street vendors, particularly in the Elizabethan age, but continuing until the nineteenth century.

Now Available - Brass and Glass: Optical Instruments and Their Makers

Brass and Glass
Optical Instruments and their Makers
*** Now available in paperback ***

Brass and Glass: Optical Instruments and their Makers
is an encyclopaedia of optical instruments, and the individuals and companies, both historical and contemporary, who have made them. It contains over 2000 alphabetical entries, including:

Optical instrument makers and brands
Telescopes
Binoculars
Microscopes
Cameras
Navigation instruments
Surveying instruments
Military optical ordnance
Laboratory & educational instruments
Optical terminology

There are appendices containing information on selected related subjects such as optical glass and eyepiece designs.

The inspiration for the book came from my interests in stargazing, photography, microscopy and bird-watching. These involve using telescopes, microscopes, binoculars and cameras, and soon I began to take an interest in classic and vintage optical instruments. I found the lack of reference material frustrating - I would see an interesting looking vintage telescope at auction, but to find out more about the maker I would have to buy extraordinarily expensive reference books, many of which are out of print. Further, the information I sought was frequently scattered around multiple sources, and time-consuming to collate. I wanted an affordable, simple, encyclopaedic reference in which I could find the name of the maker or optical instrument and a concise, but informative article about them. This book is my attempt to remedy that gap in the literature.

Since the invention of the telescope and the microscope in the early seventeenth cetury there have been countless makers of optical instruments. It would be impossible to include an entry for every one of them. However, most makers the general reader will encounter are currently included, and new entries will be added in future editions.

A draft table of contents for the first edition may be found here (opens in a new tab).
Much of the content of Brass and Glass: Optical Instruments and their Makers relates to instrument makers or organisations of the past. However, many are still in business, or have been absorbed into other businesses which are still trading. A list of current websites of, or relating to some of the companies and organisations which appear in the book may be found here (opens in a new tab).

Optical Instruments and Their Makers


It’s been a while since I’ve updated you on my work in progress, so here goes: It’s non-fiction, and the title is Brass & Glass: Optical Instruments and Their Makers.

The inspiration for the book came from my interests in stargazing, photography, microscopy and bird-watching. These involve using telescopes, microscopes, binoculars and cameras, and soon I began to take an interest in classic and vintage optical instruments. I found the lack of reference material frustrating - I would see an interesting looking vintage telescope at auction, but to find out more about the maker I would have to buy extraordinarily expensive reference books, many of which are out of print. Further, the information I sought was frequently scattered around multiple sources, and time-consuming to collate. I wanted an affordable, simple, encyclopaedic reference in which I could find the name of the maker or optical instrument and a concise, but informative article about them. This book is my attempt to remedy that gap in the literature.

It’s up to over 1700 entries now, and I’m working with several subject-matter experts to get critique feedback on the content. That will lead to a new raft of updates and additions then, when that’s complete, hopefully it’ll be close to being ready for publication.

Using Crossed Polarising Filters on a Conventional Microscope

A short while ago I posted an article about sugar crystals imaged in a microscope with crossed polarising filters. I promised to show the setup I used to achieve this, so here we are.


What you see here is a Charles Baker microscope with a Cooke microscope lamp providing Köhler Illumination. (The link is to my previous article explaining Köhler Illumination). I've implemented the crossed polarisation very simply.

I have a small polarising sheet that I have cut into two two-inch squares.
I use one of the squares in a filter slot in the microscope light.
And I place the other over the microscope slide, but under the objective lens. This sheet of polarising filter I rotate, while viewing through the microscope, until I see the best contrast.
And the result... I get to see these wonderfully colourful renditions of the crystalline structure of the sugar (see my earlier post).


A microscope used with crossed polarising filters is sometimes referred to as a polariscope.

Polariscope

In general, a polariscope is an optical inspection device used to detect internal stresses in glass and other transparent materials such as plastics, synthetic resins, crystalline materials, etc. A polariscope is composed chiefly of a light source and two crossed polarised lenses. Material to be examined is placed between the two polariscope lenses and viewed through the lens opposite the light source lens. It is commonly used in detecting the optical properties of gemstones.

Köhler Illumination


Köhler Illumination is a form of microscope sample illumination, invented by August Köhler, (see below), that provides even light across the field of view, and a light cone that matches the numerical aperture of the objective lens. It is suitable for either viewing or photography. It normally consists of a collector lens near the light source, together with a field iris, and a sub-stage condenser with a condenser iris. The focus of both the collector and condenser lenses is adjustable, as is the aperture of each of the irises.

The Cooke microscope light you see here has both an adjustable collector lens (the big lever pointing straight up), and an adjustable field iris (the small lever you see further to the right). You can click on the image to see it enlarged.

It also has a knob to adjust how bright the light is, and slots where filters can be inserted. This particular model of light is designed by Cooke to be used with a Cooke microscope, but it can easily be used with any conventional microscope.

The microscope I've shown in the picture above is by Charles Baker. It has a sub-stage condenser and iris, and a sub-stage mirror. The mirror has a plane face and a curved face. The plane face of the mirror is used in conjunction with Köhler Illumination, since the focusing of the illuminating light is achieved by the collector lens and the sub-stage condenser.



Using Köhler Illumination

The collector lens is focused to form an image of the light source in the plane of the sub-stage condenser iris. The condenser lens is focused to form an image of the field iris in the sample plane. The two irises are adjusted to provide the required light cone. Thus, when the sample is in focus the image of the light source is completely de-focused, resulting in even illumination.

Some microscopes have built-in Köhler illumination. In this case, the principle is the same, but the practicalities of the adjustments may be different.

August Köhler

August Köhler, (1866-1948), was a German scientist who made several innovations in microscopy. He is best known for his invention of Köhler Illumination in 1893. In 1900 he began to work for Carl Zeiss, where he continued to work until 1945, three years before his death.

Sugar Crystals Viewed in Polarised Light

Nature produces some amazing and beautiful sights. We only have to watch the well-produced nature programmes to see this. Sometimes, however, we need optical instruments to help us see these wonders. 


In this case I've used a microscope to look at simple sugar crystals. The field of view is about 1.05mm by 1.59mm, and the sugar is viewed through crossed polarising filters.


I prepared the microscope slide for this rather simply. It is certainly not elegant, nor is it in any way a professional looking slide - but it works. I dissolved sugar in water until no more would dissolve. I then dripped a small amount onto the slide and waited for it to dry. I built up a rectangular trough around it using some of my wife's nail varnish, and the last coat I used to build up the trough also cemented the cover-slip into place. Simple.




I will do a another post to show the equipment setup I used for this but, in brief, it was a vintage Charles Baker microscope, with Köhler Illumination using a Cooke microscope light and two polarising filters.



For now I just wanted to share the pictures with you in the hope you will enjoy viewing them.
