Ablative Absolute.
 
419.
 A noun or pronoun, with a participle in
agreement, inay be put in the Ablative to define the time or circumstances
of an action.  This construction is called the Ablative Absolute: - 
[1][The Ablative Absolute is perhaps of instrumental origin.  It is,
however, sovu* times explained as an outgrowth of the locative, and in any
event certain locative constructions (of place and time) must have
contributed to its development.] 
-  Caesar, acceptis litteris, nintium
mittit  (B.  G.  v.46), having received the letter, Cav'ar sends
a messenger (the letter having been received).  
- quibus rebus c5gnitis Cacsar spud militts
co-utiOnittur  (B.  C.  i.  7), having learned this, Casar makes
a speech to the soldiers. 
- fuga*to- omni equitati  (B.  G.  vii.  68), all the cavalry being put to flight. 
- interfecto InditioniSr5  (id.  vi.  2), upon the death of Indutiomarus. 
- uSudum hienie c5nfecta in finis NerviOrum
contendit  (id.  vi.  3), though the winter was not yet over,
he
hastened into the territory of the Nervii. 
- compress! [sunt] conattis nillS tumulti
piblice concitatS  (Cat.  i.  11), the attempts were put down
without erciting any general alarm. 
- ni vo-bis quidem omnibus re etiam turn
probati  (id.  ii.  4), since at that time the facts were not
yet proved even to all of you. 
NOTE:  The ablative absolute is an adverbial modifier of the
predicate.  It is, however, not grammaticaHy dependent on any word in the
Sentence:  hence its name absolute (absolitus, i.e.  free or unconnected).
 A substantive in the ablative absolute very seldom denotes a person or
thing elsewhere mentioned in the same clause. 
a. An adjective, or a second noun, may
take the place of the parti2iple in the Ablative Absolute construction:
-
[2][The present participle of esse, wanting in Latin (§170.  b), is
used in Sanskrit and Greek as in English.] 
-  exigna parte aesttttis rellqua 
(B.  G.  iv.  20), when but a small part of the summer was left (a small part of the summer remaining).  
- I'.  DomitiS Ap.  Clandie- c5nsulibus
 (id.  v.1), in the consulship of Lucius Domitius and Appius
Claudius (Lucius Domitius and Appius Claudius being consuls).  [The
regular way of expressing a date, see §424.  g.] 
- nil d*p*andum Tencr5 duA et auspice TenorS
 (Hor.  Od.  i.  7.27), there should be no despair under
Teucer's leadership and auspices  (Teucer being leader, etc.).  
 b. A phrase or *ause, used substantively,
sometimes occurs as ablative absolute with a participle or an adjective
:  
-  incert5 quid peterent  (Liv.  xxviii.  36), as it was uncertain what they sho*:  aim at (it being uncertain, etc.).  
- compertS v5num esse formidinem 
(Tac.  Ann.  i.  66), when it was found that the alarm was
groundless. 
- cer praeterestur dsmbnstrAt5  (mv.  ii.  84), when the reason for omitting it has been erplained (why it is passed by being explained).  
NOTE:  This construction is very rare except in later Latin. 
c. A participle or an adjective is
sometimes used adverbially in the ablative absolute without a substantive:
 
-  consultS  (Off.  i.  27), on
purpose (the matter having been deliberated on).  
- mihi optato veneris  (Att.  xiii.  28.  8), *ou will come in accordance with my' wish. 
- aersn5  (Liv.  xxxi.  12), under
a clear sky (it [being] clear). 
- nec auspicatS nec htatS  (id.  v.38), with no auspices or favorable sacrylce. 
- tranqullib, ut *unt, quilibet guberrator
est  (Sen.  Ep.  85.  34), in goo* weather, as they say, any man
