hemicycle

The defect of the Hemicycle, as this hollow type of dial was called, was that it could not be read accurately for short intervals.

In the hemicycle above are the Virgin and Child under a Byzantine canopy with angels and founders on either side.

Then to the upper part of this second cord they apply on its lower side the broad part of a hemicycle.

But let us step on to the hemicycle of the Belvedere, and view some works greater than any we have yet seen or even imagined.
