This simple wooden cup is reputed to have been used by Alexander Peden, the 'Prophet of the Covenant', at secret conventicles or prayer meetings.
Peden was born near Sorn, Ayrshire in 1626. He studied in Glasgow and taught as a schoolmaster in Tarbolton before becoming minister at New Luce, Wigtownshire.
In 1662, having refused to sign the Oath of Allegiance to the King, he was ejected from the parish. He spent the next three years as a wandering field minister preaching all over south west Scotland.
In 1665 he was declared a rebel and went into hiding in Ireland. On his return in 1673 he was captured and spent the next four years as a prisoner on the Bass Rock.
Peden is now part of Covenanting folklore and is commemorated in numerous placenames. In Galloway, for instance, there is Peden's Pulpit near Kirkcolm, while Colmonell, just over the border in Ayrshire, has Peden's Stone.
