Sundial
A Sundial is a timekeeping device that uses the position of the sun's shadow to indicate the time of day. It typically consists of a flat plate, often marked with hours and positioned on a raised pedestal, known as a gnomon. As the sun moves across the sky, the shadow cast by the gnomon falls on the marked plate, allowing us to read the time based on the position of the shadow relative to the hour markers.
In the Tomb Raider Universe sundials can be found in the original Tomb Raider and Lara Croft Tomb Raider: Anniversary.
Tomb Raider
In the original Tomb Raider the sundial is just a decorative item with no relevance to the game. This changed with the Tomb Raider I-III Remastered, where the trophy It's About Time! requires us to find all ancient time devices. One of these is a sundial in the level Palace of Midas, inside the garden leading the the Midas Statue.
Tomb Raider Anniversary
In the Croft Manor of Tomb Raider Anniversary Lara finds a Sundial Gnomon inside the Treasure Vault. She needs it to complete the Sundial Riddle.
