Saint Bricín (c. 590–650; also known as Bricin, Briccine, DaBreccoc, Da-Breccocus) was an Irish abbot of Tuaim Dreccon in Breifne (modern Tomregan, County Cavan), a monastery that flourished in the 7th century.
Investigations by the Breffni Antiquarian and Historical Society show that the present townland of Mullynagolman (located about two miles southeast of Ballyconnell) corresponds to the original site.
His most distinguished surgical achievement relates to his care of a serious skull wound on an Ulster noble of royal blood named Cenn Fáelad mac Aillila.
As a result, Cenn Fáelad developed an almost perfect memory and a keen interest in study at the three colleges of the university[citation needed]—Brehon Law, History and Poetry, and Classical Learning—going on to become its most distinguished scholar and poet.
Following his studies Cenn Fáelad produced three famous works, on law, Irish grammar and history, which include references to exploits of the Ulster Red Branch Knights.
