The
Holy Water font was originally the fountain forablutions , "cantharus" ("phiala"), placed in the centre of the atrium of thebasilica can still found in the East, especially atMount Athos , at Djebeil inSyria , and at Haia-Napa in the Island ofCyprus . These fountains were used by the faithful who, before entering the church, washed their hands and feet in accordance with a rite probably derived fromJudaism and even yet observed inMuslim countries. When the atrium of theChristian basilica was reduced to the proportions of a narrow court or a simple porch, the "cantharus" gave way to a less pretentious structure ["Dictionary of Architecture and Construction" (Dictionary of Architecture & Construction) by Cyril M. Harris (2005) p. 168] . It is now only exceptionally that the "cantharus" is found doing service as a Holy Water font, mainly atMount Athos , where the "phiala" of the monasteryof Laura stands near thecatholicon in front of the entrance and is covered by a dome resting on eight pillars. Vessels intended for the use of Holy Water are of very ancient origin (see on the right), and archaeological testimony compensates, to a certain extent, for the silence which historical and liturgical documents maintain in their regard. The "phiala" is a large two-handled drinking cup ["The Etymologies of Isidore of Seville" by Stephen A. Barney, W. J. Lewis, J. A. Beach, and Oliver Berghof (2006) p.400] ["Bodies From the Ash: Life and Death in Ancient Pompeii" by James M. Deem (2005) p.30] , or drinking globlet with high, curved, exaggerated handles ["Hands in Clay : An Introduction to Ceramics" by SPEIGHT, Charlotte Speight, and John Toki (2003) p.32] the upper basin of a fountain (see on the right).Other names
