About Us

Hieros is a 501c3 non-profit organization whose primary purpose is to develop our shared understanding of the sacred in both theory and practice.

We recognize that the sacred is not quantifiable, and is not identifiable only with monotheistic or non-monotheistic texts, but rather emerges from what has been termed numinous or mystical experience. Such experiences may occur in dreams or in other ways, and are central to many esoteric practices. For instance, in the Greco-Roman Mystery traditions at Samothrace and Eleusis, there were secrets imparted directly to the initiates, and those were not accessible to the uninitiated public. It is our goal to explore and develop a more robust understanding of the sacred through accurate historical research, writing, and publications dedicate to unveiling a wide range of ancient and modern traditions. .

We understand that inspirations and intuitions of the sacred enliven literature, theater, and art. We are deeply interested in what is sometimes termed mythology, that is, hieratic stories, songs, poems, philosophy, buildings, and works of art. We recognize that the heart of the humanities is rooted in the hieratic, revealed in experiences of the sublime, and the transcendence of the subject–object distinction.

We encourage forms of education and encounter that recognize the sacred as inspirational presence that unites both culture and nature.   We are interested in what may be termed initiatory pedagogies, that is, in understanding how the sacred is revealed in the classical humanities, in the context of particular landscapes and sacred sites, in unexpected urban manifestations, and in wilderness.

We seek to understand the higher and deeper dimensions of human consciousness as expressed through cultural forms, art, literature, philosophy, architecture, and cultural integration with landscape and water.

More About the Symposium

Across Western Europe, the Anglo-Celtic Isles, North America, and Australia are countless ancient sacred sites. Megaliths, cairns, and other stones or rock formations often mark the sacred places whose mysteries are conveyed in myths. In this rare one-day symposium, we will explore new ways of understanding our relationship with the landscape as marked by sacred places interwoven with myths and ancient mysteries. What are the mysteries and hidden aspects of the ancient landscapes right around us? Join us to come to understand more deeply the land, hills, mountains, rivers, and seas that surround us. Speakers will include well-known authors John and Caitlín Matthews, James Cowan, John Carey, Arthur Versluis, and Kresimir Vukovic.
