The round towers are indisputably of pagan origin, and of antiquity so great as to precede written history. There is no doubt that the early Irish were sun and fire worshippers, and many excellent reasons may be given for the belief that the round towers were built by the Druids for purposes of religion.
Every tower has an extensive view to the East, so as to command an early sight of the rising sun, the dawn being the favorite hour for celebrating sun-worship. Every tower contains, at its base, so extraordinary a quantity of ashes and embers as to compel the conviction that, in each, a sacred or perpetual fire was kept burning. In every locality where a round[pg 122] tower stands, there linger among the peasantry traditions pointing to a use sacred but not Christian. Perhaps the most significant indication of their former character as places sacred to sun and fire-worship is found in the names by which, to the present day, they are known among the common people. The generic Irish name for the round tower is Colcagh, fire-God; but the proper names designating particular towers are still more characteristic. Turaghan, the Tower of Fire; Aidhne, the Circle of Fire; Aghadoe, the Field of Fire; Teghadoe, the Fire House; Arddoe, the Height of Fire; Kennegh, the Chief Fire; Lusk, the Flame; Fertagh, the Burial Fire Tower; Fertagh na Guara, the Burial Fire Tower of the Fire Worshippers; Gall-Ti-mor, the Flame of the Great Circle; Gall-Baal, the Flame of the Community; Baal-Tinne, the Fire of the Community, and many similar names, retain the memory and worship of the Druids when written records are silent or wanting.
In addition to the significance contained in the names of the towers, the hills, mountains, or islands on which they are situated have, very frequently, designations conveying an allusion, either to the circle, a favorite and sacred figure in Druidical holy places, or to the sun or fire worship. Another curious circumstance, still further identifying the round tower with the rites of sun worship, is found in the fact that wherever this form of religion has prevailed, it has been accompanied by well or spring worship, and, generally, by the veneration of the ox as a sacred animal. Most of the Irish round towers have near them springs or wells still regarded as holy, and concerning which many tales of miraculous cures are told, while in not a few instances there yet linger in the same neighborhoods legends of sacred cows, usually the property of some famous local saint or hero.
The round towers of Ireland are, in fact, a portion of a vast system of towers of identical construction, and by following the geographical course of these structures, the march of fire worship from the East may be determined with some accuracy. Pass from Ireland to Brittany, and there, in the mountainous or hilly districts, several towers are found exactly like those of Ireland. In the north of Spain several remain; in Portugal, one; in the south of Spain they are numerous. Opposite the Spanish coast, in the north of Africa, there are also many, being found in various places in Morocco, Algeria, Tunis, and Tripoli. In Sardinia, several hundred are still standing; and written testimony to the purpose for which they were erected is abundant among the Sardinian records. In Minorca, among many others, is the famous Tower of Allaior. The mountain districts of south Italy have numbers of them, and they are also found on several hills in Sicily. Malta has the Giant's Tower, in every particular of appearance and construction identical with the Tower of Cashel in Ireland. Cyprus has them, and they still remain in Candia and on the coast of Asia Minor. In Palestine none have yet been found, or at least have not been recorded by travellers or surveyors; a fact that may, perhaps, be fully accounted for by the zeal of the Hebrews in destroying every vestige of Canaanitish idolatry; but, with some probability, it is conjectured that the "high places" broken down may have been towers of the sun, for the Canaanites were fire worshippers, and the name Baal is found alike in Palestine and Ireland.
In Syria, north of Palestine, they begin again; are found in Armenia, and in the Caucasus, so numerously as to crown almost every hill-top. East of the Caspian Sea they abound, and towards the centre of Asia as far as records of exploration and travel present reliable accounts of the country. Returning[pg 124] to the shores of the Mediterranean, their existence on the northern coast of Africa has been mentioned. In Arabia and on the Egyptian shore of the Red Sea, they stand in considerable numbers, are found in Persia, Afghanistan, Beloochistan, India, Ceylon, and Sumatra, in some places being still used, it is said, for fire worship.
Throughout this vast extent of territory there is no material difference in the shape, appearance, or construction of the round tower. In Sumatra and Java, as in Ireland, the door is elevated, the building divided into stories; the walls are constructed of many sided hewn stones, the upper story is lighted by four windows looking to the cardinal points, the cornice has the same kind of zigzag ornamentation, and the roof is constructed in the same manner, of overlapping stones. Even the names are nearly the same, for in India and Ireland these buildings are Fire-Towers, Fire-Circles, or Sun-Houses.
Another bit of circumstantial evidence going to prove that the round towers of Ireland were erected by a people having the same religion and similar religious observances as the natives of India is seen in the legends concerning the Indian towers. In India, the local traditions tell how each of these towers was built in one night by some notable character who was afterwards buried in it. In Ireland, the same legend is found; to the present day, the peasants of the neighborhood telling with gusto the story of the tower being first seen in the early morning, rising toward the sky on a spot where, the evening before, no preparations for building had been visible.
The Tower Tulloherin, for instance, was built in one night by a monk who came to the neighborhood as a missionary. Finding the people inhospitable, and unable to obtain lodging for the night, he determined to remain, believing there could[pg 125] not be found in Ireland a locality more in need of missionary work. So, on the evening of his arrival, he began to build, and by morning the tower was finished, and he took up his abode in it, preaching from its entrance to the crowds attracted by the fame of the miracle. The story of the Tower of Aghagower is similar, save in one particular, the saint in this case being aided by angels. Kilmackduagh was built in one night by angels without human assistance, the work being done at the solicitation of a saint who watched and prayed while the angels toiled.
Ballygaddy has a history somewhat less miraculous, the local peasant historian attributing its origin to a "giont" of the neighborhood. Having received a belligerent message from another "giont," he took a stand on Ballygaddy hill to watch for the coming of his antagonist, proposing, as the humble chronicler stated, "to bate the head aff the braggin' vagabone if he said as much as Boo." For seven days and nights he stood upon the hill, and at the end of that time, as may readily be believed, "his legs wor that tired he thought they'd dhrop aff him." To relieve those valuable members he put up the tower as a support to lean on. The bellicose gigantic party who proposed the encounter finally came to time, and lovers of antiquities will be glad to learn that the tower-building giant "didn't lave a whole bone in the blaggârd's ugly carkidge." After the battle, the victor "shtarted for to kick the tower down," but, upon second thought, concluded to put the roof on it and "lave it for a wondher to thim little mortials that come afther him," for which consideration all honor to his memory.
The Tower Ardpatrick was, according to tradition, built under the auspices of Ireland's great saint, while the high tower on the Rock of Cashel is attributed, by the same authority,[pg 126] to Cormac Macarthy, king and archbishop of Cashel, who, being once engaged in hostilities with a neighboring potentate, needed a watch-tower, so summoned all his people, built the tower in one night, and, at sunrise, was able by its help to ascertain the location of the opposing army and so give it an overwhelming defeat. The Glendalough Tower was built by a demon at the command of Saint Kevin. This saint had conspicuously routed Satan on a previous occasion; so the arch-fiend and all the well-informed of his subjects kept at a safe distance from Glendalough, not caring to take any risks with so doughty a spiritual champion as Saint Kevin had proved himself to be in more than one encounter.
