The Black Nag
This is an English country dance tune
Here’s a slightly different version in Bmin that I picked up online several years ago:
T: Black Nag, The

Actually, I just noticed- I usually play that a little closer to Q: 260.
Black Nag was first published in Playford’s Dancing Master (1686) edition.
Black Nag - the Dance
The tune "Black Nag" is used for an English 17th century 72-bar dance of the same name.
Since the tune is only 24 bars in length, three reiteratiions of the tune are needed for "once through" the dance.
