The line of poetry is being projected onto the north face of Castle Rock
A line of romantic poetry is being projected onto the rock beneath Edinburgh Castle for Valentine's Day.
The words "Look to the living, love them, and hold on" will shine on the north face of Castle Rock.
The line is from the poem Disenchantments by the award-winning Scottish poet Douglas Dunn.
It was projected on the rock for an hour on Saturday night and the spectacle will be repeated from 1800 GMT to 2300 GMT on Sunday.
The event is part of the Carry a Poem campaign run by the City of Literature Trust.
Ali Bowden, director of the Edinburgh Unesco City of Literature Trust, said: "We are delighted that Historic Scotland is supporting the Carry A Poem campaign, and joining us in bringing poetry to Edinburgh Castle, the iconic cultural image of Scotland's capital city.
"This one-off projection joins five other poems shining throughout the city - two onto the city chambers, the new extension of the Usher Hall, the National Library of Scotland and at the foot of Leith Walk - all of which can be enjoyed until March."
Robyn Marsack, director of the Scottish Poetry Library, said: "Douglas Dunn's lines are so appropriate: they say that love endures, like the Castle Rock which they'll illuminate for a night."
The poetry campaign wants to encourage and inspire Edinburgh's residents to carry poems they love with them.
