"Lá Pilib a' Chleite" is a phrase for the day of judgement, which I confess to never having understood. But I came across an article in An Sagart by Pádraig Ó Fiannachta, which explains all.

Pilib a' Chleite is an owl, and will not be seen during daylight until the day of judgement.

For the curious among you...

Le meas, a chara, Lá Philib an (nó a')Chleite...

Ní doigh liom go bhfuil seimhiú ceart ansin, Larry. Mar atá sé agamsa atá sé ag Pádraig Ó Fiannachta, pé scéal é.
Tá fo-riail éigin i gceist anseo nach cuimhin liom.

Go raibh maith agat as an nasc sin, a chara.

Ach de réir FGB (lch.735 [Lá]) le seimhiú...??

Sliocht as alt le Máirtín Ó Corrbuí a nocht san iris "Feasta" sa bhliain 1983:

"Is mar a chéile iad Lá Philib an Chleite agus Lá Thadhg na dTadhgann nó Lá Sheoin Dic -- is é sin le rá lá nach dtiocfaidh choíche. Tugtar Pilib an Chleite ar an ubhlachán [sic], éan oíche nach áil leis an lá."

Tá brón orm, Larry, bhí mé ar strae. Ní chloisim an seimhiú.

Is suimiúil sin a Aonghuis. Go raibh maith agat as muid a chur ar an eolas faoi.

Disregarding the seimhiú issue, I was unaware of the use of "Philip of the feathers" until a few months ago when somebody asked me to translate Judgement Day. It was only when I consulted Ó Dónaill's FGB that I came across this alternative.

So I'd like to thank Aonghus for highlighting this interesting phrase. Go raibh míle maith agat, a chara.

Fáilte romhat, a Larry.

Pádraig Ó Fiannachta had a tree in the church garden which was dying, so he had an artist carve it into a sculpture - sort of like a totem pole, representing Pilgrims. Pilib a' Chleite, as a symbol of eternity, topped the pole.
