When is Medieval?

A lady was asking for a medieval alphabet for a layout. I dug out my references on medieval calligraphy and snickered. Some of the fonts being offered could be called medieval. Some could not. But I need to establish when the medieval period was. In the UK, many historians believe that the medieval period started with the Battle of Hastings in 1066 and ended with the Battle of Bosworth in 1485, which ended the Wars of the Roses, and started the time of the Tudors.

The medieval era started in 1066 and ended in 1485. The renaissance began with the Tudors. Tudors lasted from 1485 to 1603.

Thus endeth my history lesson.
