What is the oldest source about Apollo's birth?

The Homeric Hymn to Delian Apollo, dating to the 7th century BCE, is the oldest surviving account of Apollo's birth on Delos.

Was Apollo born at Delphi?

No. Apollo was born on Delos. Delphi became one of his major sanctuaries later, but it was not his birthplace. This is a common misconception.

Where was Apollo born?

Q: Where was Apollo born?

Apollo was born on Delos, a small sacred island in the Aegean Sea's Cyclades archipelago, according to the Homeric Hymn to Delian Apollo, the oldest surviving source on his birth (7th century BCE).

Apollo was born on Delos, a small sacred island in the Aegean Sea's Cyclades archipelago. This comes straight from the Homeric Hymn to Delian Apollo, our oldest source on the god's birth—and it matters because Delos became the religious center of the entire Greek world because of this one birth.

What the oldest source actually says

The Homeric Hymn to Delian Apollo (7th century BCE) is where this story starts. The poem describes Leto, Apollo's mother, in labor and in pain, calling out to the island: "Will you be willing to be the seat of my son Apollo and make him a temple?"

Delos was supposedly a floating island—untethered, unanchored. But when Leto arrived, desperate to give birth, Poseidon fixed it in place. She delivered Apollo there, and the island was transformed from worthless to sacred. The hymn states that after Apollo's birth, people began sailing to Delos specifically to honor him with festivals and sacrifices.

This wasn't just mythology talking. By the Classical period, Delos actually was the religious powerhouse of Greece—home to the Delian League's treasury, host to the Delia festival every four years. The myth explained why.

What most people get wrong

Most modern retellings say Apollo was born at Delphi, or that Delphi was always his main sanctuary. Wrong on both counts. Delphi came later and for different reasons (the Oracle, Python, the omphalos stone). Delos was first. It was the original sacred site. Delphi was Apollo's second act.

This confusion probably happens because Delphi became more famous in later Classical times—more tourists, better stories, bigger political influence. But if you're tracking Apollo's actual origins in Greek religion, you have to start on that three-kilometer rock in the middle of the Aegean.

Primary sources

Homeric Hymn to Delian Apollo (7th century BCE) — Lines 1-140. The foundational text. This is where the story comes from, not Homer's Iliad, not Ovid, not later retellings.
Herodotus, Histories 4.33-35 — Confirms Delos as an ancient sacred site and describes pilgrimages there.
Thucydides 3.104 — Historical confirmation of the Delia festival and Delos's religious status.

The bigger picture

Delos mattered because it was neutral ground. No city-state owned it. That's why it could host the treasury of the Delian League without creating political chaos. And that neutrality worked because of the myth—because everyone agreed Apollo was born there first, before he claimed Delphi, before he claimed anywhere else.

The island was so sacred that according to the myths, no one could be born or die there. It was reserved for Apollo alone. That restriction shaped centuries of Greek religious practice.
