Produced in 1990, Limite temps was offered to the Ville de Montréal by Hydro-Québec following the work’s restoration. Renamed Limite temps II, the sculpture is now installed in the Île-de-la-Visitation nature park, near the reception pavilion.

The installation is composed of a stone monolith representing a door that opens and closes, a metaphor for the passage of time. A bronze handle and lock are affixed to the frontal surface of the block, and a bolt and strike are attached to the side. On both sides of the door, an eye is carved into the stone. In front of and behind the monolith, bas-relief fossils are placed on the ground, evidence of past changes and the origins of human intervention in nature.

Limite temps was commissioned by Hydro-Québec in 1990 for the refurbishment of the Walker (now Simon-Sicard) Dam, situated on Rivière des Prairies. Initially installed near the church of La Visitation, Ruba’s work was integrated into Sculpture: Séduction 90, a permanent pathway of fifteen works organized by the Conseil de la sculpture du Québec.
