Manx, also written quaaltagh, from quaail (= Irish and Gaelic comhdháil) meeting
A great deal of superstitious belief surrounds the qualtagh of New Year’s Day. A darker complexion was considered luckier. A male qualtagh was considered luckier than a female, and a red-headed person was exceptionally unlucky.
A qualtagh bearing gifts was considered beneficial as it was considered representative of what the New Year would bring. When meeting a qualtagh it was polite to provide them with the best offerings of the house - the finest food and drink available.
