03.01.27: Level 3+ (review); Dooge LXXV [6] review; (1) the predicative dative / the dative of purpose and result; (2) the double dative; the dative of reference

Item Caesar, animō ad dīmicandum parātus, exercitum suum ēdūxit et septem cohortibus (1) praesidiō [dative] (2) castrīs [dative] relictīs cōpiās triplicī aciē īnstrūxit.

  • Caesar likewise, his mind prepared for battle, led out his army and, seven cohorts having been left behind (1) as a guard (2) for the camp [ = to guard the camp], drew up his forces in a triple line.

You can see that there are two nouns in the dative case. We will look at these separately.

(1) praesidiō: the dative of purpose

We have a noun in the dative case very often (but not exclusively) occurring after the verb esse, the dative indicating the purpose of that noun or the result which is achieved by that noun; this is also known as the predicative dative or the dative of purpose and result.

septem cohortibus (1) praesidiō … relīctīs

  • seven cohorts having been left behind (1) as a guard …

English can convey a similar idea using expressions such as: ‘as a’, ‘a cause of’, ‘a source of’ or ‘a means of’, for example:

  • How can I be ¦ of assistance?
  • I did it ¦ as a favour.
  • I use these glasses ¦ as a means of / for protection.
  • That is ¦ (a cause) of great concern.
  • That’s ¦ (a source) of benefit

Below are examples of nouns which commonly use this construction:

argūmentō esse: to be proof

auxiliō esse: to be a help; to be of help

bonō esse: to benefit; to be (a source) of benefit

cūrae esse: to be a concern; to be (a cause) of concern

dolōrī esse: to be a cause of grief

dōnō esse: to be (as a) gift (Compare English: he gave him a gift │ He gave a book to him as a gift.)

  • Hōs librōs dōnō mīsit │ He sent these books as a gift

exemplō esse: to be (as) an example (Compare English: I’ll show this picture to you ¦ as an example.)

exitiō esse: to bring destruction; to be a source of destruction

honōrī esse: to be an honour

laudī esse: to be a credit

malō esse: to be a cause / source of harm

mūnerī esse: to be (as a favour); to be of service

odiō esse: to be an object of hatred

onerī esse: to be a burden

perīculō esse: to be a (source of) danger

praesidiō esse: to be a means of protection

pudōrī esse: to be a cause / source of shame

salūtī esse: to be a salvation

subsidiō esse: to be (a source of) help / support

ūsuī esse: to be of use (to benefit)

(2) castrīs: the dative of reference

septem cohortibus (1) praesidiō (2) castrīs … relīctīs

  • seven cohorts having been left behind (1) as a guard (2) for the camp

This indicates the person / thing  for whom / which the purpose is intended or who is affected by it: 

Since this construction most often occurs with the two parts, it is known as the double dative:

(1) Māgnō ūsuī [dative of purpose] (2) nostrīs [dative of reference] fuit (Caesar)

  • It was (1) of great service (2) to our men.

Translations may not convey the double dative so literally:

bellum est (1) exitiō ¦ (2) incolīs 

[Literally: war is (1) a source / cause of destruction ¦ (2) to the inhabitants]

  • War brings destruction to the inhabitants.

Illa fēmina, quae līberōs interfēcit (1) odiō [ii] omnibus est.

[Literally:  That woman who killed her own children is (1) a source of hatred (2) for everybody

  • That woman who killed her own children is hated by everyone.

The order may be reversed:

Puella (2) mihi [dative of reference] est (1) cūrae [dative of purpose]

  • The girl is (1) of concern (2) to me

(2) nōbīs  (1) exemplō fuit ad imitandum │ He was (1) an example (2) for us to imitate

Caesar omnem ex castrīs equitātum (2) suīs (1) auxiliō mīsit. (Caesar)

  • Caesar sent all the cavalry in the camp (1) as a relief (for the purpose of relief) (2) to his men

A neat way of remembering this construction is a two word quotation from Cicero:

Cui [dative of reference] bonō [dative of purpose]?

[Literally: to whom (is it) of advantage?]

  • Who benefits?
