Patrick a shorn pig every year. And this, indeed, is still given.

When the solemnity of Easter approached, Patrick considered that there
was no place more suitable to celebrate the high solemnity of the
year--_i.e._, the Easter--than in Magh-Bregh, the place where the head
of the idolatry and druidism of Erinn was--viz., in Temhair. They
afterwards bade farewell to Dichu, son of Trichim, and put their
vessels on the sea; and they proceeded until they anchored in
Inbher-Colptha. They left their vessels in the Inbher, and went by
land until they reached Ferta-fer-féc, and Patrick's tent was fixed in
this place, and he cut the Easter fire. It happened, however, that
this was the time in which the great festival of the Gentiles--_i.e._,
the _Fes of Tara_--was usually celebrated. The kings and princes and
chieftains were wont to come to Laeghaire Mac Neill to Tara, to
celebrate this festival. The druids and the magicians were also wont
to come to prophesy to them. The fire of every hearth in Erinn was
usually extinguished on that night, and it was commanded by the king
that no fire should be lighted in Erinn before the fire of Tara, and
neither gold nor silver would be accepted from any one who would light
it, but he should suffer death for it. Patrick knew not this thing;
and if he knew it, it would not prevent him.

As the people of Tara were thus, they saw the consecrated Easter fire
at a distance which Patrick had lighted. It illuminated all
Magh-Bregh. Then the king said: "That is a violation of my prohibition
and law; and do you ascertain who did it." "We see the fire," said the
druids, "and we know the night in which it is made. If it is not
extinguished before morning," added they, "it will never be
extinguished. The man who lighted it will surpass the kings and
princes, unless he is prevented." When the king heard this thing, he
