"Divining the Immeasurable is a retrospective look at Zelenak's practice, referencing early, monumental wood sculptures and explorations of fibreglass, which resulted in elegant, volumistic abstractions. After such investigations of form, space, and often, light, Zelenak reduced his scale while broadening his subject matter to universal proportions. Choosing materials deep-rooted in human technological history, such as lead, copper, and bronze, he produced objects that are as equally laden with cultural and spiritual heritage. Sculptures and wallworks dating from the 1970s through 2014 bear evocative forms -- vehicles, vessels, tools such as dowsing rods and ladders, and natural phenomena such as trees and celestial bodies -- represented in a deceptively simple, iconic fashion. Zelenak's motifs can be viewed as archetypes of modern existential feeling, ancient beliefs or messages, references to more recent folklore and myriad other forms of language or knowledge." --Publisher's description.
