# Cato the Elder > Roman politician, soldier and writer (234–149 BC) **Wikidata**: [Q180081](https://www.wikidata.org/wiki/Q180081) **Wikipedia**: [English](https://en.wikipedia.org/wiki/Cato_the_Elder) **Source**: https://4ort.xyz/entity/cato-the-elder 1. **Analyze the Request:** * **Role:** Knowledge base editor. * **Task:** Write a structured, LLM-friendly biographical entry for "Cato the Elder". * **Constraint 1:** Use ONLY provided source material. No fabrication. * **Constraint 2:** Write proportionally to the source material (more context = longer). * **Constraint 3:** Use ALL provided facts and connections. * **Constraint 4:** Output in a specific Markdown structure (Summary, Biography, Contributions, FAQs, Why They Matter, Notable For, Body). * **Constraint 5:** No Schema.org or JSON-LD. 2. **Analyze the Source Material:** * **Raw Description:** Roman politician, soldier and writer (234–149 BC). * **Detailed Knowledge (Related Entities):** * *Human*: Member of Homo sapiens. * *Ancient Rome*: Country (inception 8th century BC). * *Writer*: Uses written words. * *Historian*: Scholar of history. * *Economist*: Professional in economics. * *Poet*: Writes poetry. * *Politician*: Holds/seeks government positions. * *Philosopher*: Extensive knowledge of philosophy. * *Orator*: Public speaker. * *Soldier*: Member of armed forces. * *De Agri Cultura*: Book by Cato. * *Origines*: Historical work by Cato. * *Basilica Porcia*: Building in Rome (inception 184 BC). * *Dorsa Cato*: Wrinkle ridge (likely on the moon, named after him). * **Key People:** Henry David Thoreau (irrelevant context, just a comparison point in the source list, but I must check if there's a connection. The prompt says "Key People", but the list only shows Thoreau. I should ignore Thoreau unless there's a direct link mentioned, which there isn't. I will focus on Cato). * **Created / Developed by:** * *Carthago delenda est*: Latin phrase used by Cato. * **Structured Properties:** * *Aliases*: Marcus Porcius Cato, Marcus Porcius Cato Maior, Marcus Porcius Cato Major, Marcus Porcius Catus, Marcus Porcius Cato Sapiens, Cato Censor, Cato Sapiens, Cato Major, Marcus Portius Cato. * *Dates*: 234–149 BC. * *Description*: Roman politician, soldier and writer. 3. **Drafting - Section by Section:** * **Summary:** * Needs to answer "Who is Cato the Elder?". * Facts: Roman politician, soldier, writer. Lived 234–149 BC. * Draft: Cato the Elder was a Roman politician, soldier, and writer who lived from 234 to 149 BC. He is historically significant for his roles in government and the military, as well as his literary contributions. Also known as Marcus Porcius Cato, he is famously associated with the phrase "Carthago delenda est." * **Biography:** * *Born*: 234 BC (Place not explicitly in source, but "Ancient Rome" is the country context. I will stick to the date provided in the description). * *Nationality*: Ancient Rome (implied by "Roman politician" and the "Ancient Rome" entity). * *Education*: Not provided. * *Known for*: Being a politician, soldier, writer; using the phrase "Carthago delenda est"; writing *De Agri Cultura* and *Origines*. * *Employer(s)*: Not explicitly listed as "employers", but he was a politician/soldier in Ancient Rome. * *Field(s)*: Politics, Military, Literature, History (implied by *Origines* and *historian* tag). * **Contributions:** * *De Agri Cultura*: A book by Cato. * *Origines*: A historical work by Cato. * *Basilica Porcia*: A building in Rome (inception 184 BC). The source links this to Cato via the "Created / Developed by" or "Related" context? Actually, looking at the raw text, "Basilica Porcia" is under "Related". However, standard knowledge (which I must suppress if not in source) says he built it. Let's look closer at the source. The source lists "Basilica Porcia" under "Related". It does *not* explicitly say "Cato built this" in the text provided, but usually, in these knowledge graphs, if it's listed under the person's "Detailed Knowledge", it implies a connection. Wait, the prompt says "Use ONLY the provided source material". The source lists "Basilica Porcia" under "Related". It does not explicitly state the relationship (e.g., "built by"). However, "Carthago delenda est" is under "Created / Developed by". I must be careful. I will mention the works explicitly attributed to him (*De Agri Cultura*, *Origines*, *Carthago delenda est*). For *Basilica Porcia*, it is listed in the "Detailed Knowledge" section under the person. I will include it as a related entity he is associated with, perhaps implying development, but strictly speaking, the text just lists it. However, the prompt says "Use ALL provided facts and connections". The connection is that it is in the list of items related to him. I will frame it as an associated building. * *Carthago delenda est*: Latin phrase used by him. * **FAQs:** * Q: What are Cato the Elder's famous works? A: *De Agri Cultura* and *Origines*. * Q: What is Cato the Elder known for saying? A: "Carthago delenda est." * Q: What were Cato the Elder's occupations? A: Politician, soldier, writer, orator, historian. * Q: When did Cato the Elder live? A: 234–149 BC. * **Why They Matter:** * Significance: He wrote *De Agri Cultura* (earliest Latin prose? - not in source, so don't say that). He wrote *Origines*. He used the phrase "Carthago delenda est" which implies a stance on Carthage. He was a "Censor" (alias "Cato Censor"). * Draft: Cato the Elder matters for his multifaceted career as a statesman, military leader, and author. His literary works, such as *De Agri Cultura* and *Origines*, provide insight into Roman thought and history. Additionally, his persistent use of the phrase "Carthago delenda est" highlights his political influence regarding the conflict with Carthage. * **Notable For:** * Writing *De Agri Cultura*. * Writing *Origines*. * Using the phrase "Carthago delenda est". * Association with the Basilica Porcia (inception 184 BC). * Having a wrinkle ridge named *Dorsa Cato* after him. * Aliases like Cato Censor and Cato Sapiens. * **Body:** * *Structure*: H3 subheadings. * *Identity & Occupations*: List the roles (politician, soldier, writer, historian, economist, poet, philosopher, orator). Note: The source lists these as "Related" things, implying he fits these categories. * *Literary Works*: Detail *De Agri Cultura* and *Origines*. * *Political & Military Life*: Mention the phrase "Carthago delenda est". Mention the Basilica Porcia (184 BC). * *Legacy & Namesakes*: Mention *Dorsa Cato*. * *Aliases*: List the various names. 4. **Refining and Checking Constraints:** * *Check*: Did I include Henry David Thoreau? No, he is in the "Key People" section of the source, but there is no text connecting him to Cato. The prompt says "Use ALL provided facts and connections". If there is no connection text, I shouldn't force one. I will omit Thoreau to avoid hallucination. * *Check*: Did I include "economist"? Yes, it's in the related list. * *Check*: Did I include "poet"? Yes, in the related list. * *Check*: Did I include "philosopher"? Yes, in the related list. * *Check*: Did I include "orator"? Yes, in the related list. * *Check*: Did I include "human"? Yes, trivial but in the list. * *Check*: Dates. 234–149 BC. * *Check*: Basilica Porcia date. 184 BC. * *Check*: Dorsa Cato. Wrinkle ridge. 5. **Final Polish of the Output Text:** * Ensure the tone is encyclopedic. * Ensure the structure matches the prompt exactly. *Self-Correction during drafting*: The source lists "economist", "poet", "philosopher", "orator" under "Related". While Cato is historically known for some of these, the source *only* lists them as "Related" items. I must phrase it carefully. "He is associated with the roles of..." or "His related occupations include...". The prompt says "Use ALL provided facts and connections". The connection is the list itself. I will list these as his fields or occupations in the Biography and Body sections. *Regarding Basilica Porcia*: The source lists it under "Related" with an inception date of 184 BC. It does not explicitly say "Cato built it". However, in the context of a biography entry for Cato, listing a building with a specific date under his "Detailed Knowledge" implies a connection. I will mention it as a building associated with him from that time period. *Regarding "Carthago delenda est"*: This is under "Created / Developed by". This is a strong connection. I will state he used this phrase. *Regarding "Dorsa Cato"*: This is a wrinkle ridge. Likely named after him. I will list it as a namesake. 6. **Constructing the Final Output:** * **Summary**: Cato the Elder was a Roman politician, soldier, and writer who lived from 234 to 149 BC.

It does not explicitly say "Cato was an economist".
