On the main banqueting table in the Great Hall sits a “mether,” which is a four-sided, four-handled Irish drinking vessel carved of wood. See also the methers in the Tower House Parlor.
An example from the 16th century with the provenance “Kilcolman, Co. Cork” is currently in the Limerick Museum.
Other objects on the table here, in the Parlor and in the Tower House Parlor, are modeled after Tudor-era facsimiles in wood and pewter found at Barrycourt Castle, Co. Cork.
