The Battle of Carnn Chonaill (Author: [unknown])

paragraph 37

'Tis he that wrought the wondrous miracle at Clonmacnois when they were bearing him thither to his burial.

The jester came to him and asked a boon of him repeatedly. So he (the dead king) put his hand out over the ground, and took his handful of the sand, and. flung it into the jester's bosom, and made a glowing mass of gold thereout. So that is Guare's last deed of bounty.

This tale above is (also called) the Battle of Diarmait and Guare of Aidne.
