The earliest depiction of a pipe and tabor is, according to Jeremy
Montagu, the Misericord In Exeter Cathedral which seems to date from
c1230, ie about 40 years before Lincoln. Both these depictions however
appear to show a pipe of flabiol type due to girth and position of
hands. The roughly contemorary deer bone pipe from White Castle is
also of this type, in other words it can be played either with one or
two hands. There is little evidence of the modern type of three hole
pipe before the 15c.
