Croick Church in Sutherland has, etched into the glass of its windows, several messages.
Scratched by the desperate hands of the tenants of Glencalvie after being evicted from their homes in the infamous Highland Clearances. Cleared to make way for sheep, a more profitable 'flock' for the landowner than rent-paying tenants.
James Gillanders, Factor to the Robertsons of Kindeace, after several previous attempts finally managed to evict the tenants from the glen on the 24th May 1845. Eighteen families numbering some ninety people, took refuge in the churchyard.
Facing displacement and destitution, they scratched their names on the outside of the church glass, so that at least the memory of their passage might be recorded.
Today you can stand where they stood, run your fingers over the glass they touched, and feel the grooves they scratched ripple under your skin.
Most glass we look through provides a view, one we may look upon and smile.
The view through these windows is altogether darker.
It is the interior of the human heart.
