Propositiones ad Acuendos Juvenes/Problems/15 - De Homine/Historical Note

Historical Note on Propositiones ad Acuendos Juvenes by Alcuin of York: Problem $15$: De Homine

Alcuin himself gives $6$ as the answer to this.

Bede correctly gives $7$, as do most translators and interpreters.

It is assumed that Alcuin has made a Fencepost Mistake.

Careful counting, as has been demonstrated here, indicates that the answer is indeed $7$.
