That's 200 years later than the usual use of the word "hobilar", but gives some idea. Hobilar were usually described as unarmoured.
So, a hobilar was mounted infantry. They were (somewhat) replaced by mounted archers; kinda indicates that they either learned to shoot or just got rid of the horse.
just seems likely but im not hugely familiar with irish bows so can anyone help englighten me to irish bows. i know a bit on the longer bows but did they ever use shorter bows of any type?
Seems there was a decent range of bows in use here after the 12thC; seems norse and english bows were the main influence. Halpin's recent book on weapons and armour in Viking & Medieval Dublin describes a lot of the bow finds.
