In one of the most poetic renderings of the Tobit narrative, the backlit figures of Tobias and the Angel crest a rocky promontory, with the Angel pointing the way ahead, his arm reaching out over the dog at his side. The prolific landscape etcher Waterloo looked primarily to the work of Hercules Seghers (1589/90–after 1633) and Jacob van Ruisdael (1628/29–1682). This print is consistently, and justifiably, marked as his masterpiece. The rugged Alpine landscape, likely concocted, underscores the important role of the Guardian Angel in protecting travellers.
