Joshua has been actively investigating the crystal skulls since 1983, having visited and occasionally worked
with a number of the so-called ancient skulls.
He also will be working as a consultant for the two hour documentary about the crystal skulls to be shown on the SciFi channel in America (May, 2008) and is involved with a feature film that
portrays a special story with the crystal skulls.
He is the co-author of two crystal skull books, "Mysteries of the
Crystal Skulls Revealed" (with Nocerino & Bowen, 1989) and Journeys of the Crystal Skull Explorers ("Kristallen schedels" --
Een groot mysterie nader bekeken" published by Uitgeverij Akasha, is the Dutch title) with his partner and ex-wife
Blue Arrow Rainbow.
Joshua has given numerous crystal skull lectures all over the world and has been a part of various media programs. He has
been working with Blue Arrow Rainbow since 2001. They are affectionately known as the Crystal Skull Explorers. Between the two of them,
they have gathered an interesting circle of crystal skulls who participate with the Explorers during their public work.
Joshua believes the crystal skulls are "vital for the future of our world and have key information contained inside
that will help Humanity create a world of peace by 2012". He serves as the chairman of the board of the World Mystery
Research Center and
was the initiator of this series of Crystal Skull Festivals which began in Holland in 2006, continued in Hungary in 2007 with more festivals planned for 2008.
"Portal de Luz" (Portal of Light) -- was the first crystal skull that came to Joshua in 1990, a
gift from his former wife Vera Lopez, a brasilian who is a tour conductor for spiritual journeys to Peru. "Portal", as he and Blue Arrow Rainbow call "him", is a world traveler that also has appeared
occassionally on TV. This skull was made by a very skilled Brazilian carver, is smoky quartz and weighs about 10 lbs. One
time, while Joshua was being interviewed in Las Vegas, the video camera stopped working during the entire interview (for the
internet broadcast) and then started to work after "Portal" was put away. Johann Pachelbel is "Portal's" favorite composer.
