Pocket globes came into fashion in Georgian England and
remained
popular until the mid-nineteenth century. They were the executive toys
of their era, being three inches, or thereabouts, in
diameter. Their cases were often lined with star charts or
other information. Joseph Moxon, credited with bring pocket globes to
England in 1673, is thought to have gotten the idea from the Blaeus, in
Holland.
Orreries
and Tellurions are models of the solar system, usually with a clockwork
mechanism to demonstrate their movements relative to each other.
These astronomical instruments are each one of a kind, and no
design will be
repeated.
