Condition & Value Assessment
Condition Assessment
Very Good. The marble shows some surface erosion and weathering consistent with outdoor exposure in a saline maritime environment, but structural integrity is high.
Estimated Market Value
Inestimable. As a protected state monument and UNESCO World Heritage site component, it is not subject to private market valuation.
Auction Estimate
N/A (Cultural heritage property; non-salable).
Provenance History
Commissioned by the Venetian Republic as part of the Clocktower construction on the north side of Piazza San Marco. It has remained in situ since its installation.
Art Historical Significance
Crucial icon of the Venetian Republic's political and religious identity. The Clocktower served as the gateway between the domestic square and the commercial Merceria, making this specific lion one of the most visible symbols of Venetian authority.
Notable Features
The open book signifies that the work was created during a time of peace for the Republic. The blue of the mosaic is characteristic of 'Venetian Blue' glass production.
Condition Issues
Atmospheric pollution crusting, minor biological colonization in crevices, marble sugaring (granulation) due to salt air, and potential localized loss of mosaic gold leaf.
Conservation Recommendations
Periodic non-invasive cleaning of surface deposits, monitoring of the marble's surface cohesion, and maintenance of the architectural waterproofing above the niche to prevent water ingress behind the mosaic.
