Greek and Roman Mythology Family Tree | Genealogy of the Gods, Zeus's Family, Trojan War Characters Explained

The biggest reason the relationships in Greek and Roman mythology feel confusing is that the generational genealogy of the gods and the character relationships of the Trojan War are mixed together. The genealogy of the gods is a story of bloodlines connecting parents, spouses, and children, while the Trojan War characters are relationships formed within the epic, so the picture becomes much clearer when you look at the two layers separately.

In this article, we will first organize the family relationships of the gods centered on Zeus by spouse and children, and then go over the character relationships of the Trojan War and Odysseus's family. Finally, we will also touch on the fact that genealogies can be told differently depending on the tradition.

Zeus's Family: Spouse and Children Relationships

Zeus's spouse is Hera, and Ares is presented as the son of the two gods. The relationship of Zeus + Hera → Ares forms one axis of this family tree.

In Athena's case, the mother is different. Since Athena is presented as the child of Zeus and Metis, it helps to first note that Hera is not Athena's mother, so the genealogy doesn't get tangled.

In the same way, Apollo and Artemis are the children of Zeus and Leto, and Hermes is the son of Zeus and Maia. To summarize, it looks like the table below.

What stands out in this table is that each child has a different mother. Since Zeus's children were not all born from the same mother, it is more accurate to connect each parent pair one by one when drawing the relationship diagram yourself.

If you want to look broadly at the genealogy of the generations above Zeus or the overall positions of the Olympian gods by generation, the Genealogy of the Gods in Greek and Roman Mythology page continues from here. The relationships get more complicated as you go up, so it's easier to understand by following Zeus's family step by step first.

Trojan War Characters: Relationships Surrounding Helen

The starting point of the Trojan War relationship diagram is the fact that Helen is Menelaus's wife. Paris becomes entangled with this marital relationship, leading to the war, and in the Iliad Helen is presented as a figure placed in a wartime relationship with both Paris and Menelaus. So rather than simply grouping Helen as a figure of one side, it is more accurate to place her in a position caught between the two men.

The center of the Greek camp is the brothers Agamemnon and Menelaus. The two are described as sons of Atreus, meaning the brotherly lineage of Atreus → Agamemnon and Menelaus forms the structure of the Greek side. Since the younger brother Menelaus is Helen's husband, the brotherly lineage and the marital relationship become the two axes that tie together the war's character relationships.

To see in more detail how the relationship between Helen and Paris leads to war, refer to the Helen and Paris page, and if you want to follow the war narrative itself, also check the Iliad Summary.

Odysseus's Family: A Separate Axis

Separate from the Trojan War characters, Odysseus's family also forms its own axis. Odysseus is a household head with his wife Penelope and son Telemachus.

The attitudes of the gods surrounding this family are also worth including in the relationship diagram. In the Odyssey, Athena appears as a figure who helps the family of Odysseus, Penelope, and Telemachus, while Poseidon appears as a figure hostile to Odysseus. In other words, the relationship diagram of Odysseus's family can be summarized as a narrow family unit of 'husband, wife, and son,' overlaid with a helping god and a hostile god.

Parts That May Vary by Tradition

Mythology is a body of material passed down through multiple traditions mixed together, so even the same god may be described with different parents or spouses depending on the text. The relationships organized in this article are based on the genealogies presented for each figure, and do not confirm all variant traditions. If a particular figure's genealogy differs across sources, it is most accurate to check based on the wording of the original texts.

One more point to note is that the genealogy of individual gods and the character relationships of the Iliad and the Odyssey are different layers. The genealogy of the gods is a generational bloodline, while the Trojan War characters are relationships within the war narrative, so it is better to understand the two groups separately rather than forcibly merging them into a single tree.

If you are new to mythology, where you start reading also affects how well you understand the relationships. If you get the flow down on the Reading Order for Mythology Beginners page, this relationship diagram will feel much less daunting.
