Why do we call a tribrach a tribrach?

My mind was wandering and I wondered why we call a tribrach a tribrach? Yes, I understand that "tri" is related to the three feet. So I tried looking it up and I'm more confused than ever when I read this definition:

"a metrical foot of three short syllables of which two belong to the thesis and one to the arsis".

So, why? Can you help?

But in the course of my searching I found this video about checking and adjusting. It's well done by Seco:

Plus there are some other videos there as well.

brachium is Latin for "arm"

Probably in left field but I always equated "brach" with brac" as in bracket. Then you add the tri for the three "feet" thingy.

I always assumed it's because the spring plate and the base plate have three arms.

I always thought the same. The more you know!

I didn't know what an Arsis is

So I googled it.

Apparently it's this

Frequently Arsis comes teamed with Cath, as in Amorphous Catharsis.

Now you know.

A bracket is a right angle support

Doesn't it "bracket" the instrument at a right angle to the tripod head?

Good answer.

How long have tribrachs been around?

While Wild had had a couple of styles, their "standard", removable tribrach has been around since the 1920's. The European style 3 screw base has been around longer than that, but I can't put a finger on a beginning. But these weren't removable.

Those examples are weird. How far should we trust an analysis by someone who is silently accepting “He and me . . . walk”? Anyway, here is Edmund Gosse, at the end of his article on “Verse” for the eleventh edition of the Encyclopaedia Britannica (1910-1911). :

It is extremely doubtful whether any youthful poet was even helped by prosodical instruction; his earliest measures are imitative; he does not compose consciously in “tribrachs” and “iambs”; he would gape in astonishment if asked to define the “pyrrhichian hypothesis”; his bursts of enthusiasm are not modified by a theory of “trisyllabic equivalence.” The old formula of verse, “variety in unity,” holds good in all languages, countries, and times; the delicate rapture involved in a brilliant combination of rhyme and metre is a matter which is regulated, indeed, on a consideration of the laws of prosody, but depends on other and wider qualities of a moral and an aesthetic order.

Consider the German name, dreifüß. I believe it means three legs or three feet.

Here's an on line translation:

With only 2 years of high school Latin behind me, the first time I saw a tribrach and was told its name, that name immediately made sense, because it has 3 arms. There's no question in my mind as to the origin of the term.

OK - I can accept that. But I certainly hadn't thought of it terms of "arms", but rather I would have thought in terms of feet or legs.

And your 2 years of high school Latin certainly stuck with you better than my 2 years stuck with me. I do remember that the main thing I learned from Latin is that I learned English.
