I don't know whether tis is strictly "on topic" in relation to your question but on a visit to Pompeii recently I was amazed by the sundial at the Temple of Apollo.
 
This was buried in 79AD and is far froma a "vertical obelisk type dial"

With apologies if I am preaching to the far more knowledgeable.

Subject: Armillary Dial

After Roman dials with their vertical obelisk type gnomons,
when did sundials with gnomons in parallel to the planet's axis
first appear? I found an entry in the BSS Glossary  2000
for the introduction of an armillary dial in 1598 by Valentin Pini.
Would he have been the first one to have installed a 'modern' dial?
Is there a history of the development of the dial ?
