It was in poor condition when discovered in the collection of the Mooney family of Doon, County Offaly in 1821, with many of the figures and bosses missing; some of the current elements were added during late 19th century restorations.
[6] The bosses are linked by flat mounts decorated with pale yellow and red enamel cloisonné,[7] and interlace depictions of zoomorphic animals.
[9] The crosses divide each arm into four separate sections; those above and below cross-arms contain four rows of figures in high relief, numbering 52 in total.
[5] The figures all have similar faces but are individualised in other ways: some wear beards, some clasp their hands while others fold their arms, some carry axes, and one holds a book.
[8][3] The shrine was probably produced in the River Shannon area, most likely at the monastery in Clonmacnoise, County Offaly, then a cell for Lemanaghan, parish of Manchan's church and residency.
[11] The influential antiquarian, archaeologist and painter George Petrie was the first scholar to describe the shrine after finding it in the care of the Mooney family in 1821.
