See pieces like it you can buyBefore the photograph, the print: the Orloj engraved in 1837, its tower and dials rendered in the crisp romantic line of the Biedermeier print trade. An astronomical clock is a public complication — a machine that tells a whole square the hour, the calendar, and the state of the heavens at once — and the engraver treats it accordingly, as portraiture. Paired with Fridrich's photograph of a generation later, it makes a small history of how we looked at the same machine.
