Would a glass diving bell be practical?

I read about Alexander the Great's legendary glass diving bell which he supposedly descended to 150 metres in. What would be the practicality of this?

I think you have it right. This is strictly a legend. I doubt a glass diving bell could have been made at that time. Maybe a helmet but even then there is the problem of an air supply.
