8th-10th century AD. A Hiberno-Norse type penannular bronze brooch with oval hoop, widening towards the terminals, inset glass cabochon to each sub-triangular terminal and thick pin with ring finial. See Murray, E., Mccormick, F.M., 'Doonloughan: a seasonal settlement site on the Connemara coast' in Proceedings of the Royal Irish Academy Section C, January, 2012, pp.1-51, fig.3. 14.4 grams, 96mm (3 3/4"). UK gallery, acquired in the 2000s. Property of an English gentleman. Large penannular brooch types originally developed by Vikings residing near the Irish Sea, were soon adopted in Scandinavia and further towards the east. However, this brooch presents affinities with the Pant-y-Saer, Llanfair-Mathafarn-Eithaf brooch from Wales (inv.92.228H of National Wales Meum), and with a 9th-10th century brooch discovered at the Irish site of Doonloughan. The brooch of Doonloughan shows the same type of pin. It is probable that the brooch is of Celtic origin.
