26. est. We say 'would be.'

aetate, ablative of specification. Translate 'when he was now advanced in
age' (_i.e_. 'late in life'), and see the note on _fessus_, 23, 15.

30. 1. accidit. This is one of several impersonal verbs which take for
their subject a clause of result (ut ... occiderit).

3. ut ... iret, a clause of result; used as the subject of esset, mos
being predicate.

quis. After _si, nisi, ne_, and _num_, this is not the interrogative, but
an indefinite pronoun ('any one'),

occidisset, indirect for _occiderit_, which would be the form used in the
laws; or it may be explained as subjunctive by attraction to iret.

7. transeant, not 'they are crossing,' but 'they are to cross.' The
direct form would be _transeamus ('How in the world are we to get
across?'), subjunctive because the question expresses doubt. This is
called the deliberative subjunctive.

10. progressus, 'after advancing.'

11. revertebatur. This verb is deponent in the present, imperfect, and
future.

16. humi, locative, 'on the ground.'

ne. See the note on 23, 24.
