The Image of Irelande; Plate 2. An armed company of the kern (Gaelic light infantry), carrying halberds and pikes and led by a piper, attack and burn a farmhouse and drive off the horses and cattle. Note the characteristic léine (saffron-dyed shirt with baggy sleeves bloused around the waist) and ionar (short open-sleeved jacket) worn by the kern.

Kern are mentioned in Shakespeare’s Macbeth (Acts I and V):

The merciless Macdonwald–
Worthy to be a rebel, for to that
The multiplying villanies of nature
Do swarm upon him–from the western isles
Of kerns and gallowglasses is supplied;

[…]

Mark, king of Scotland, mark:
No sooner justice had with valour arm’d
Compell’d these skipping kerns to trust their heels,
But the Norweyan lord surveying vantage,
With furbish’d arms and new supplies of men
Began a fresh assault.

[…]

I cannot strike at wretched kerns, whose arms
Are hired to bear their staves: either thou, Macbeth,
Or else my sword with an unbatter’d edge
I sheathe again undeeded.
