Latin t‑model circle analysis (Michael Clay Thompson style) — Quoniam de civitatis utriusque… — four‑level breakdown (parts of speech, parts of sentence, phrases, clauses)

1. Sense and literal gloss

Latin: Quoniam de civitatis utriusque, terrenae scilicet et caelestis, debitis finibus, deinceps mihi uideo disputandum.

Literal gloss / smooth translation: Since concerning the proper bounds (debítis finibus) of both cities (civitatis utriusque), namely the earthly and the heavenly, henceforth it seems to me that a discussion is necessary. / "Since, about the rightful limits of duty of both the earthly and the heavenly city, I see that from now on it must be debated."

2. Quick syntactic diagnosis (overall)

Structure: a subordinate causal frame introduced by Quoniam (since) followed by a prepositional/noun phrase that supplies the topic/content, then the main finite verb uideo with a verbal-nominal complement (disputandum). The subject ego is implied. Mihi is a dative of interest/agentive sense with the impersonal/verbal construction. Deinceps is an adverb of time.

3. Level 1 — Parts of speech (word-by-word)

• Quoniam — subordinating conjunction (causal: "since / because")
• de — preposition (takes ablative)
• civitatis — noun, genitive singular of civitas, civitatis ("of the city/state")
• utriusque — indefinite/ordinal adjective/pronoun in genitive singular ("of both") modifying civitatis
• terrenae — adjective (fem. gen. sing.) "earthly" (in agreement with civitatis, explanatory/appositive)
• scilicet — adverb/parenthetical "namely / that is to say"
• et — coordinating conjunction "and"
• caelestis — adjective (fem. gen. sing.) "heavenly" (paired with terrenae)
• debitis — adjective/participle in ablative plural modifying finibus; here: "due / rightful / proper" ("debítis finibus" = "the rightful bounds")
• finibus — noun, ablative plural of finis, finis ("bounds / limits") — object of the preposition de
• deinceps — adverb "from now on / henceforth" (modifies the main predicate/action)
• mihi — dative singular ("to/for me") — dative of reference/interest
• uideo — verb, 1st person singular present active indicative ("I see / it seems to me") — finite main verb
• disputandum — gerundive/gerund form functioning as a verbal-nominal complement ("to be discussed / that one must discuss"); often read as a gerundive of necessity with impersonal sense

4. Level 2 — Parts of the sentence (MCT style: subject side / predicate side)

In T‑model terms, sentences are binary: a subject side and a predicate side. Here the subject is implied (ego), the predicate contains the seeing + infinitival/nominalized action and adverbials.

Notes on parts of sentence:

• Subject side: implied personal pronoun ego (not written).
• Predicate side: finite verb uideo is the predicate head; its complement is the verbal noun/gerundive disputandum. Mihi marks the person for whom the action/necessity obtains; deinceps gives temporal force.
• The whole fronted phrase introduced by Quoniam functions as an adverbial/circumstantial element (cause/topic) modifying the predicate; in the t‑model it sits outside the core subject/predicate binary as the supplying circumstance that motivates the seeing.

5. Level 3 — Phrases: grouping into circles (MCT circle grouping)

We group words that behave together into circles (phrases). Each circle is a unit in the sentence.

1. Circle A (causal/topic phrase begun by the conjunction):
   Quoniam + [de + finibus (abl. pl.)]
   Inside that: finibus (head) + debit is (abl. pl.) (modifier) + genitive phrase civitatis utriusque ("of both states") modified in apposition by terrenae scilicet et caelestis ("namely the earthly and the heavenly").
   Rendered as a single topical circle: (Quoniam • de [finibus • (debítis) • (civitatis utriusque • terrenae scil. et caelestis)])
2. Circle B (adverbial/time): (deinceps) — single adverbial circle (henceforth)
3. Circle C (dative of interest): (mihi) — dative circle
4. Circle D (predicate nucleus): (uideo + disputandum) — verb + verbal complement grouped as the predicate circle

6. Level 4 — Clauses

Clause inventory:

• Main clause (matrix): [(ego) deinceps mihi uideo disputandum]. Finite verb uideo — this is the independent clause that carries the judgment.
• Subordinate/circumstantial frame: Quoniam de civitatis utriusque, terrenae scilicet et caelestis, debitis finibus, — introduced by quoniam, a causal subordinating conjunction; supplies the reason/topic (an adverbial clause of cause or topic). It is not a full clause with its own finite verb; rather it is a subordinating phrase built on the preposition de + ablative finibus and its modifiers.
• Within the subordinate phrase: a genitive noun phrase civitatis utriusque with an appositive/adjectival clarification terrenae scilicet et caelestis (two adjectives in apposition: "the earthly and the heavenly [city]").

7. T‑model (circle diagram) — compact visual arrangement

Below is a compact T‑model representation using circle labels. The left big circle = Subject side; right big circle = Predicate side. Additional circles are arrayed around the predicate and the fronted causal circle (Quoniam ...).

Reading the T‑model in prose: The fronted causal/topic circle (Quoniam + the prepositional noun phrase about the bounds of both cities) provides the reason. The implied subject ("I") on the left is the thing the predicate comments about. The predicate circle contains the seeing/assessment uideo together with the verbal complement disputandum; the dative mihi marks the person for whom the necessity/seeing holds, and deinceps gives temporal force.

8. Small points and interpretive caution

• disputandum can be read as a gerundive (necessitative sense, "must be discussed") or as a verbal noun/gerund acting as the complement of uideo. The sense in context gives a necessity/impersonal sense: "it seems to me that henceforth there must be discussion."
• mihi functions as dative of reference (to me it seems / for me the discussion is necessary).
• The apposition terrenae scilicet et caelestis explicitly names the two kinds of "city/state" in the genitive, so the internal grouping in the topic circle is tight: civitatis utriusque = the genitive head, apposed by the two adjectives.

9. Short, final English paraphrase

"Since, on the matter of the rightful bounds of duty of both cities — namely the earthly and the heavenly — I see that the question must be debated from now on."
