John Grigsby was born in Dover, Kent in 1971. He attended the local Grammar school before studying archaeology and ancient history at the University of North Wales, Bangor - a move prompted by his interest in the Arthurian and Celtic legends (which he discovered aged 15). Following his bachelors degree he remained in Bangor where he studied the Welsh mythological cycle, the Mabinogion, for his Masters Degree under Dafydd Glyn Jones and the now National Poet of Wales Gwyn Thomas. He recieved a distinction for his thesis 'Myth and the Mabinogi' that explored the Welsh myths from a Jungian perspective.
In 1996 John met the author Graham Hancock in a Canterbury bookshop and as a result of their meeting became Graham's researcher for the next four years, during which period he co-authored with Graham and Robert Bauval 'The Mars Mystery' (Penguin books) as well as researching and contributing theories to Hancock's 'Heaven's Mirror'. John worked as a researcher on the channel 4 documentary, 'Quest for the Lost Civilization', that accompanied this book and which also contained reference to his controversial 'Angkor-Draco' sky-ground correlation.
The most fulfilling part of his stint as a researcher were his research trips across the United States and Canada for 'The Mars Mystery' and 'Underworld' in which he interviewed leading academics in the fields of space exploration and climate change. He was also one of the guest authors on the 1998 'Stars and Signs' tour of Egypt along with Robert Bauval, Graham Hancock, John Anthony West, Robert Temple, Yuri Stoyanov, Michael Baigent and Colin Wilson.
In 2002 John published his first solo book 'Warriors of the Wasteland' that argued the origin of the medieval Grail legend lay in pre-Christian Celtic practices which could be illuminated using parallels from other Indo-European mythologies. John's theory argued that the wounding of the Fisher King was a dim memory of a fertility rite that was once widespread in the ancient world and that the remains of the so-called 'bog-bodies' from prehistoric north west Europe were evidence for such rites. This field of study lead to John's role as a consultant to the filmakers, Independent Image, on archaeologist Francis Pryor's Channel 4 documentary 'Britain BC'.
In 2005 following leads brought to his attention during the writing of 'Warriors...' John produced a second solo book 'Beowulf and Grendel' in which he turned to Old English legend, arguing that the Beowulf 'legend' was a poetical retelling of a religious clash in age of migration Denmark between the indigenous followers of the fertility goddess Nerthus, who was worshipped in sacred lakes with human sacrifice, and the incoming Danes who were followers of Odin. The warrior Beowulf diving into the mere to behead Grendel's hideous mother being symbolic of the warrior cult of Odin overcoming the lake goddess Nerthus and her cult.
For the last few years John has worked for English Heritage at Richborough Roman Fort in Kent, as well as spending the winters lecturing in the Centre for Flexible Learning and the School of European Culture and Languages at the University of Kent at Canterbury where he has lectured in archaeology and myth, (including Celtic archaeology and mythology; Anglo-Saxon legend, Dark Age Britain; Bronze Age Greek archaeology; Neolithic and Bronze Age Britain).
In 2009 John appeared on BBC 1's 'The One Show' in an interview with Dan Snow on the importance of the Roman invasion of Britain (click here to view). In 2010 John was interviewed on his theories concerning ancient Celtic and Germanic sacrifice for the three-part Discovery Channel program 'Blood for the Gods' (in the UK 'Human Sacrifice'). In 2012 he appeared on BBC South East Today, again to talk about the Roman invasion (click here to view).
He is currently working on a novel based around the ancient site of Avebury in Wiltshire and which includes many of his favourite subjects: Tolkien, archaeology; ancient religion; Native American traditions; archaeo-astronomy and altered states of consciousness.
John’s main interest lies in revealing the shamanic and astronomical roots of our native myths and legends, and finding parallels with them in other worldwide tribal traditions.
