He was born at Springhall in Lanarkshire on 6 November 1824, the third son of William Forlong of Erines and his wife, who was the eldest daughter of General Gordon Cumming Skene of Dyce in Aberdeenshire. He joined the Indian Army in 1843 and fought in the Mahratha Campaign of 1845-46. He later filled various posts including that of Secretary and Chief Engineer to the government of Oudh. In 1858/59 he travelled extensively in Egypt, Syria and the Middle East. Exposure to Indian religions while doing missionary work led him to abandon his Christian faith, and into some very heterodox ideas about religious origins, including those of the ancient Hebrews. These found expression in his massive work of comparative religion, Rivers of Life, with its markedly sexual, some would say blasphemous, interpretation of religious rites and symbolism. He retired from the army in 1876 and then concentrated on writing, mainly on the comparison of various religions. His huge opus "Rivers of Life" was followed by "Faiths of Man: A Cyclopaedia of Religions" which was published posthumously in 1906. Forlong was a rationalist. He was an Honorary Associate of the Rationalist Press Association, to which he left a sum of money in his will. He died at home, 11 Douglas Crescent in Edinburgh's West End on 29 March 1904. He is buried in Dean Cemetery in Edinburgh with his wife Lavinia Reddie. The grave lies in the northern Victorian extension attaching the original cemetery on one of the north-south paths.
Rivers of Life
"...the shower of phallicism that burst upon the reading public in the shape of General Forlong's Rivers of Life". The book is in two large volumes together with a huge coloured Chronological Chart of the Religions of the World representing different currents:
Tree Worship
Phallic Worship
Serpent Worship
Fire Worship
Sun Worship
Ancestor Worship
All of these originated very early in mankind’s history, and form streams flowing down the millennia and separating and commingling into the major religions.
The numerous tales of holy trees groves and gardens repeated everywhere and in every possible form justify me in my belief that Tree Worship was first known and after it came Lingam or Phallic, with of course the female form A-dama. He is the special Phallic symbol which veils the actual God and therefore do we find him the constant early attendant upon Priapus or Lingam, which I regard as the second religion of the world. Phallic Worship, the second if not the first of man’s faiths.
