“The 17th day of March yeerly is St. Patrick’s, an immovable feast, when ye Irish of all stations and condicions were crosses in their hats, some of pins, some of green ribbon, and the vulgar superstitiously wear Shamroges, 3-leaved grass, which they likewise eat (they say) to cause a sweet breath.”
1681, Thomas Dinely, Journal.
