Robert Langdon - Bibliography

Bibliography

In The Da Vinci Code and The Lost Symbol, Langdon is said to have written five books:

• The Symbology of Secret Sects
• The Art of the Illuminati: Part 1
• The Lost Language of Ideograms
• Religious Iconology
• Symbols of the Lost Sacred Feminine

At that same point in the trilogy, Langdon is preparing the manuscript for his fifth book, to be titled Symbols of the Lost Sacred Feminine. It is later revealed in The Lost Symbol that Symbols of the Lost Sacred Feminine was published and created 'quite a scandal'.
