Perusing the Internet as one does in the current situation I came across an online article from the Irish Times by Roger Stalley relating to a book he has produced on the sculpted early medieval standing crosses of Ireland - notably those at Monasterboice in County Louth. The very useful article can be seen at Ireland’s high crosses: medieval art and engineering
Similar crosses are, of course, to be found at Iona, at Ruthwell and Bewcastle in what are now the Anglo-Scottish borders, further south in northern England and, once upon a time, at Reculver in Kent where they were seemingly venerated as relics in the sixteenth century.
I have posted before about Northumbrian examples in 2014, although unfortunately it appears that the images have disappeared from the post. It can be read at The Dream of the Rood
