On a trip to Egypt in 2011, Meagan Murphy became awestruck at the size and detail of the mammoth statues depicting ancient female heroines.

Really, though, she couldn’t stop staring at their breasts.

“I was in one of the temples by the Sudanese border looking at a statue of the goddess Isis, the mother of creation,” the 54-year-old filmmaker tells The Post. “And I got a powerful gut feeling that the breasts contain ancient wisdom.”

That’s why Murphy created “The Breast Archives,” a documentary hitting iTunes today and DVD Nov. 20, featuring nine women whose ages span about four decades, talking about the complicated relationship they have with their breasts — mostly while topless.
