Who were the two brothers known as the Atridae?

The Atridae refers specifically to Agamemnon and Menelaus, who were prominent figures in Greek mythology and particularly in the context of the Trojan War. They were the sons of Atreus, which is where the name "Atridae" comes from (Atreid being a patronymic meaning "descendants of Atreus"). Agamemnon was the leader of the Greek forces during the Trojan War and also the king of Mycenae, while Menelaus was the king of Sparta and notably the husband of Helen, whose abduction by Paris led to the war's outbreak.

In contrast, Hector and Paris were sons of Priam, the king of Troy, and are not related to Agamemnon and Menelaus. Zeus and Poseidon are brothers in the Olympian pantheon but do not share a family lineage with the Atridae. Castor and Pollux, known as the Dioscuri, are twin brothers in mythology but also belong to a different mythological context and lineage. Therefore, Agamemnon and Menelaus are indeed the correct pair known as the Atridae.
