W. M. Hennessy has shown that the word _bodb_ or _badb_, aspirated _bodhbh_ or _badhbh_ (pronounced _bov_ or _bav_), originally signified rage, fury, or violence, and ultimately implied a witch, fairy, or goddess; and that as the memory of this Irish goddess of war survives in folk-lore, her emblem is the well-known scald-crow, or royston-crow.[260] By referring to Peter O'Connell's _Irish Dictionary_ we are able to confirm this popular belief which identifies the battle-fairies with the royston-crow, and to discover that there is a definite relationship or even identification between the _Badb_ and the _Bean-sidhe_ or banshee, as there is in modern Irish folk-lore between the royston-crow and the fairy who announces a death. _Badb-catha_ is made to equal 'Fionog, a royston-crow, a squall crow'; _Badb_ is defined as a '_bean-sidhe_, a female fairy, phantom, or spectre, supposed to be attached to certain families, and to appear sometimes in the form of squall-crows, or royston-crows'; and the _Badb_ in the three-fold aspect is thus explained: '_Macha_, i. e. a royston-crow; _Morrighain_, i. e. the great fairy; _Neamhan_, i. e. _Badb catha nó feannóg; a badb catha_, or royston-crow.' Similar explanations are given by other glossarists, and thus the evidence of etymological scholarship as well as that of folk-lore support the Psychological Theory. THE _SIDHE_ IN THE BATTLE OF CLONTARF, A. D. 1014 The People of the Goddess Dana played an important part in human warfare even so late as the Battle of Clontarf, fought near Dublin, April 23, 1014; and at that time fairy women and phantom-hosts were to the Irish unquestionable existences, as real as ordinary men and women. It is recorded in the manuscript story of the battle, of which numerous copies exist, that the fairy woman Aoibheall[261] came to Dunlang O'Hartigan before the battle and begged him not to fight, promising him life and happiness for two hundred years if he would put off fighting for a single day; but the patriotic Irishman expressed his decision to fight for Ireland, and then the fairy woman foretold how he and his friend Murrough, and Brian and Conaing and all the nobles of Erin and even his own son Turlough, were fated to fall in the conflict.
