Lesson 8: Reading Caesar — Applied Intermediate Latin
Apply all intermediate constructions to Caesar's De Bello Gallico, with a full analysis of BG 1.1.
Overview
This lesson puts the constructions from Lessons 1–7 to work on an authentic classical text: Caesar's De Bello Gallico (The Gallic War). Caesar's Latin is the standard benchmark for intermediate readers — his sentences are complex but consistent, his vocabulary is restricted, and his grammar is Classical Latin at its most methodical. By the end of this lesson you will have read and analyzed BG 1.1 in full.
1. Introduction to De Bello Gallico
Historical Context
Gaius Julius Caesar wrote De Bello Gallico (58–49 BCE) as a political document as much as a military memoir. He was writing dispatches from the field that were read aloud in Rome — effectively propaganda, justifying his campaigns in Gaul (modern France and Belgium) to a Senate that was growing suspicious of his power and wealth.
The work covers eight years of campaigning (58–51 BCE). Books 1–7 were written by Caesar himself; Book 8 was added by his officer Aulus Hirtius after Caesar's death.
Caesar's Rhetorical Aims
| Aim | How it appears in the Latin |
|---|---|
| Self-promotion | Caesar always referred to himself in the third person (Caesar), creating an air of objectivity |
| Justification of war | The Gauls and Germans are always described as the aggressors or as threats |
| Speed and decisiveness | Short, punchy sentences; ablative absolutes showing rapid sequences |
| Credibility | Ethnographic digressions (BG 6) showing Caesar as a scholar as well as a soldier |
Why Caesar for Intermediate Learners?
- Vocabulary is restricted: ~1,500 distinct words in all of BG
- Sentences are grammatically complex but follow consistent patterns
- The DCC (Dickinson College Commentaries) Caesar is freely available online with full grammatical notes
- Every intermediate construction appears repeatedly
2. Caesar's Five Most Common Constructions
Based on analysis of the Gallic War:
| Construction | Approximate frequency in BG | Lessons |
|---|---|---|
| 1. Ablative absolute | ~300 occurrences | Lesson 5 |
| 2. Indirect statement (ACI) | ~250 occurrences | Lesson 6 |
| 3. Temporal-circumstantial cum | ~200 occurrences | Lesson 4 |
| 4. Purpose clause (ut/nē + subj.) | ~180 occurrences | Lesson 1 |
| 5. Indirect command (ut + subj.) | ~100 occurrences | Lesson 3 |
Practical implication: If you can recognize and translate these five constructions fluently, you can read the majority of Caesar's subordinate clauses correctly.

4. Sentence-by-Sentence Analysis
Sentence 1
Gallia est omnis dīvīsa in partēs trēs
| Word | Form | Analysis |
|---|---|---|
| Gallia | nom. sg. f. | subject |
| est | 3sg. pres. ind. of esse | main verb (linking) |
| omnis | nom. sg. f. | predicate adjective agreeing with Gallia |
| dīvīsa | nom. sg. f. PPP of dīvidō | predicate adjective (periphrastic with est: "is divided") |
| in | preposition | governs accusative |
| partēs | acc. pl. f. | object of in |
| trēs | acc. pl. f. | adjective modifying partēs |
Translation: "All Gaul is divided into three parts."
Grammar note: dīvīsa est is a perfect passive (not an ablative absolute). omnis modifies Gallia as a predicate adjective, emphasizing the totality. This is Caesar's famous opening — a geographer's statement of fact presented as settled and authoritative.
Sentence 1 (continued): The Relative Clause
quārum ūnam incolunt Belgae, aliam Aquītānī, tertiam quī ipsōrum linguā Celtae, nostrā Gallī appellantur
| Word | Form | Analysis |
|---|---|---|
| quārum | gen. pl. f. | relative pronoun, referring to partēs; partitive genitive with ūnam, aliam, tertiam |
| ūnam | acc. sg. f. | direct object of incolunt |
| incolunt | 3pl. pres. ind. | main verb of relative clause |
| Belgae | nom. pl. m. | subject |
| aliam | acc. sg. f. | direct object (verb incolunt understood) |
| Aquītānī | nom. pl. m. | subject (verb understood) |
| tertiam | acc. sg. f. | direct object (verb understood) |
| quī | nom. pl. m. | relative pronoun, subject of appellantur |
| ipsōrum | gen. pl. m. | genitive of possession; "of themselves" |
| linguā | abl. sg. f. | ablative of means ("by their own language") |
| Celtae | nom. pl. m. | predicate nominative with appellantur |
| nostrā (linguā) | abl. sg. f. | ablative of means; linguā understood |
| Gallī | nom. pl. m. | predicate nominative |
| appellantur | 3pl. pres. pass. ind. | passive "are called" |
Translation: "...of which the Belgae inhabit one part, the Aquitani another, and the third [is inhabited by] those who in their own language are called Celts, in ours Gauls."
Grammar note: Caesar uses ellipsis (understood repetition of incolunt) for the second and third parts — a common rhetorical device. The relative clause quī...appellantur uses the passive appellantur with a nominative predicate noun (Celtae, Gallī). Two ablatives of means (linguā) frame the two names elegantly.
Sentence 2
Hī omnēs linguā, īnstitūtīs, lēgibus inter sē differunt.
| Word | Form | Analysis |
|---|---|---|
| Hī | nom. pl. m. | demonstrative pronoun, subject; refers back to all three peoples |
| omnēs | nom. pl. m. | adjective agreeing with Hī |
| linguā | abl. sg. f. | ablative of respect ("in language") |
| īnstitūtīs | abl. pl. n. | ablative of respect |
| lēgibus | abl. pl. f. | ablative of respect |
| inter sē | idiom | "among themselves, from each other" |
| differunt | 3pl. pres. ind. | main verb |
Translation: "All these differ from each other in language, customs, and laws."
Grammar note: The three ablatives (linguā, īnstitūtīs, lēgibus) are ablatives of respect — a common construction with verbs expressing difference, excellence, or similarity. Caesar uses the anaphoric tricolon (three parallel items) to emphasize that the three peoples are truly distinct.
Sentence 3
Gallōs ab Aquītānīs Garumna flūmen, ā Belgīs Mātrona et Sēquana dīvidit.
| Word | Form | Analysis |
|---|---|---|
| Gallōs | acc. pl. m. | direct object of dīvidit |
| ab Aquītānīs | abl. + preposition | "from the Aquitani" (separation) |
| Garumna flūmen | nom. sg. (appositive) | subject; Garumna is the name, flūmen is the appositive |
| ā Belgīs | abl. + preposition | "from the Belgae" (separation) |
| Mātrona et Sēquana | nom. pl. f. (compound subject) | subject of the understood dīvidit |
| dīvidit | 3sg. pres. ind. | main verb |
Translation: "The river Garonne separates the Gauls from the Aquitani; the Marne and Seine [separate them] from the Belgae."
Grammar note: Caesar uses chiastic word order here — the subject (Garumna) is sandwiched between the two objects. The verb dīvidit governs the accusative (Gallōs) and the ablative with ab (the thing they are separated from). Notice the second sentence is again elliptical: Mātrona et Sēquana is a compound subject with dīvidit understood.

6. How to Use the DCC Caesar Commentary
The Dickinson College Commentaries (dcc.dickinson.edu) provides a free, full-length commentary on Caesar's Gallic War with:
- Lemma entries: Every unusual word form is explained
- Grammar notes: Each construction is labeled and explained
- Core vocabulary: 1,500 most common Caesar words are flagged
- Running vocabulary lists: Organized by book and chapter
Workflow for Reading Caesar with DCC
- Read the Latin once without looking anything up. Note what you recognize.
- Identify the main verb of each sentence. Determine its tense and mood.
- Find the subject (nominative case, or understood from verb ending).
- Work outward from the main clause to subordinate clauses.
- Label constructions as you find them: AA, ACI, purpose clause, cum clause, etc.
- Consult DCC for vocabulary and any grammar points you cannot resolve.
- Translate the sentence, checking that your translation makes sense in context.
7. Practice: Reading BG 1.2 — Preparatory Notes
The next section of Caesar (BG 1.2) introduces Orgetorix and contains:
- An ablative absolute: Orgetorīgī... coniūrātiōne factā
- A cum clause (temporal-circumstantial)
- An indirect statement (ACI)
- A purpose clause
Latin text of BG 1.2 (opening):
Apud Helvētiōs longē nōbilissimus fuit et dītissimus Orgetorix. Is M. Messālā M. Pīsōne cōnsulibus, regnī cupiditāte inductus, coniūrātiōnem nōbilitātis fēcit et cīvitātī persuāsit ut dē fīnibus suīs cum omnibus cōpiīs exīrent.
Constructions to identify before translating:
- M. Messālā M. Pīsōne cōnsulibus — ablative absolute (Pattern 4: noun + noun, "consuls being M. Messala and M. Piso" = "in the consulship of...")
- regnī cupiditāte inductus — PPP (inductus) + ablative of means (cupiditāte)
- coniūrātiōnem... fēcit et cīvitātī persuāsit — paired main verbs
- ut... exīrent — indirect command after persuāsit
- dē fīnibus suīs — suīs is reflexive, referring to cīvitās (the subject of exīrent)
Your task: Using the DCC commentary, read and translate BG 1.2 fully. Identify every ablative absolute, indirect statement, purpose clause, and indirect command.

Summary: The Five Constructions in BG 1.1
| Construction | Example from BG 1.1 | Lesson |
|---|---|---|
| Ablative of respect | linguā, īnstitūtīs, lēgibus | (noun cases) |
| Relative clause | quārum ūnam incolunt Belgae | (relative pronouns) |
| Ablative of means | ipsōrum linguā | (noun cases) |
| Passive verb | dīvīsa est; appellantur | (verb system) |
| Ellipsis (understood verb) | aliam [incolunt] Aquītānī | (rhetorical style) |
BG 1.1 happens to be light on the intermediate constructions — it is a geographical statement. From BG 1.2 onward, ablative absolutes, cum clauses, purpose clauses, and ACI appear in nearly every sentence. You are now prepared to read them.
