Among other usages the Irish drove cattle through or between big fires to preserve them from the diseases of the year; and this custom was practised in Limerick and Clare down a period within my own memory: I saw it done. But it was necessary that the fires should be kindled from tenaigin [g sounded as in pagan]—'forced fire'—i.e., fire produced by the friction of two pieces of dry wood rubbed together till they burst into a flame: Irish teine-éigin from teinĕ, fire, and éigean, force. This word is still known in the South; so that the memory of the old pagan May-day festival and its fire customs is preserved in these two words Beltane and tenaigin.
Mummers were companies of itinerant play-actors, who acted at popular gatherings, such as fairs, patterns, weddings, wakes, &c. Formerly they were all masked, and then young squireens, and the young sons of strong farmers, often joined them for the mere fun of the thing; but in later times masking became illegal, after which the breed greatly degenerated. On the whole they were not unwelcome to the people, as they were generally the source of much amusement; but their antics at weddings and wakes were sometimes very objectionable, as well as very offensive to the families. This was especially the case at wakes, if the dead person had been unpopular or ridiculous, and at weddings if an old woman married a boy, or a girl an old man for the sake of his money. Sometimes they came bent on mischievous tricks as well as on a shindy; and if wind of this got out, the faction of the family gathered to protect them; and then there was sure to be a fight.
