A training gallop
A small piece of work connected with the London Borough of Brent led me to think about some other Brents: specifically, the river, the geese, the oil field, and the price of crude. Any connections or none? I decided to take myself out for a little research training gallop.
I’ve found two quite separate groups of Brents. One involves the goddess Brigantia, the river and the borough. The other group brings together the geese, the oil field and a benchmark price for crude oil. It’s been strange to find a connection between the two groups, between the goddess Brigantia and the geese. It’s just a coincidence, probably.
The borough, the river and the goddess Brigantia
Brent is a borough in the north-west of London. It’s been in existence since 1964 and is in outer London. Kilburn, Wembley, Harlesden are three well-known areas. 
The borough is named after the River Brent, a tributary of the River Thames. The river is almost 18 miles long and joins the Thames at Brentford. 
The earliest record of Brentford (and of the river) is in a letter of 705 AD when the Bishop of London suggested meeting at Breġuntford. The date suggests that this placename may be related to the Celtic *brigant– meaning ‘high’ or ‘elevated’, perhaps linked to the goddess Brigantia. 
The geese and the oilfield
The Brent Goose, Branta bernicla (Linnaeus 1758), is a small, dark goose, about the same size as a mallard. The head is black and the neck and back are grey-brown. The belly is either a pale or dark belly, depending on the sub-species. Adults have a small white neck patch. 
Here, the word ‘brent’ is derived from the Norse word ‘brendr’, meaning burnt. The geese have this name because of their charcoal colour. 
Brent geese nest on boggy Arctic tundra where they have a few months of good weather to raise a brood before the weather turns bad. They migrate south from mid-September and those which over-winter in Britain and Ireland arrive in large flocks in early October. They spend the winter feeding on eelgrass in estuaries and on crops in nearby fields. In April they fly north to the Arctic once again.
Listen to Brent geese here (scroll down a bit).
The Brent oil and gas field lies in the North Sea between Shetland and Norway and is named after the Brent goose. The field is operated by Shell UK Ltd which initially named all of its UK oil fields after seabirds, alphabetically by discovery – Auk, Brent, Cormorant, Dunlin, Eider, Fulmar and so on. The initials of the Brent field were then used in naming the parts of the Middle Jurassic geological period which make up the oilfield. These are the Broom, Rannoch, Etive, Ness and Tarbert formations, each named after a Scottish loch. Sensible from an oil-and-gas perspective perhaps but a little surprising for someone on a morning outing. 
The Brent oil field ended production at the end of February 2011, and is being decommissioned over the next 25 years. 
And the price of Brent Crude
We hear the term ‘Brent Crude’ in the financial part of the news. ‘And the price of Brent Crude is …’ So what is it and why is it important?
Brent Crude is a trading classification of sweet, light crude oil.  This type of oil was originally produced from the Brent oilfield in the North Sea and now comprises Brent Blend, Forties Blend, Oseberg and Ekofisk crudes. The classification is also known as the BFOE Quotation. It’s a benchmark crude which provides a reference price for buying and selling. Around two-thirds of the world’s oil is priced relative to it.

This is a first century AD bronze statuette of a female goddess, possibly Brigantia. The statuette is in the Museum of Brittany at Rennes (F) where she is known as Brigitte. Remarkably, from my point of view for this post, she is wearing a helmet surmounted by a goose or swan with outstretched head and wings. The helmet also has an extremely long crest.
In etymology as in the rest of life, I do know that all may not be what it seems at first glance. There is no link between Brigantia and the Brent goose. All that glisters is not gold.
I rather like, though, how the headgear of a goddess who might possibly be Brigantia but perhaps is not, can unexpectedly draw together the findings of this small research exercise. Unexpected romance.
