Maraid serc céin mardda aithne.

(lasts * love * so long * that lasts * bestowal)

Love lasts as long as munificence lasts.

A cynical view of love, jotted down by a scribe in a ninth century manuscript of a Priscian's Grammar. A modern saying given in Ó Longáin's Collection and quoted in "A Miscellany" , says "Mo ghrá thú, an rud agat!"
(I love you - what you have!)
