The Scottish Franciscan Johannes Duns Scotus was ordained priest in the diocese of Lincoln in 1291. It may be inferred that he was probably born in 1265-6; that would have brought him to 'canonical' age for ordination at the right time. His ordination in England rather than Scotland seems to require explanation. There was a sequence of changes in the mid-thirteenth century, which first gave the Scottish Franciscan friaries an independent vicariate and then restored them to subjection to the English province.
