At the base of the two Rostral Columns on Vasilyevsky Island are three sculptures by Jacques Thibault and one by Jozef Camberlein. The figures are allegories representing Russia’s largest rivers. On the northern beacon are Volga (2,193 miles) and Dnieper (1,368 miles). On the southern pole are Volkhov (139 miles) and this one Neva (46 miles). Flanking it are symbolic figureheads. In ancient Rome and Greece, it was common to attach to a rostral column the ram (rostra) from the prow of a captured enemy ship.
