In 2010, Richard Merrick took a relations journey to Scotland's Rosslyn chapel—the enigmatic fifteenth-century temple made well-known through Dan Brown's The Da Vinci Code. Little did he comprehend he used to be approximately to embark upon an highbrow and private trip that might bring about the invention of a real-life misplaced symbol—one that unearths the relationship among the world's so much sacred temples and opens up a treasure trove of misplaced technology and historical secrets.

the logo he discovers—the Venus Blueprint—is according to that planet's orbital trend, which takes the form of a five-pointed megastar whilst noticeable from Earth. As Merrick digs deeper, he realizes the Venus Blueprint used to be an essential component of the layout template of a few of the main major non secular structure round the world--including St. Peter's Basilica within the Vatican, the Roman Pantheon, the Greek Parthenon, the Temple of Jerusalem, and the nice Pyramid of Giza, in addition to many constructions designed via the secretive Freemason society.

Upon additional exam, Merrick is astounded to find that temples designed utilizing the Venus Blueprint are endowed with amazing acoustics that, while provided with definitely the right tones and frequencies, are in a position to harmonizing with Earth's resonant frequencies and evoking altered states of recognition. He then proposes a desirable proposal: may perhaps or not it's that the ancients used those harmonics to reinforce entheogenically precipitated visions—to commune with the divine and unencumber the gods within?

Supported through a magnificent array of historic learn and clinical research, The Venus Blueprint bargains compelling proof of an old misplaced tradition that used to be either spiritually and scientifically advanced.
