I am most taken with this word that I came across in this week's reading. May I inform you that crotals were found in the 1820s in an Irish bog and that there were 48 of them to be precise!
These are to what I refer
They are late Bronze age artefacts and can either be pear shaped or round. Within each one is a small pebble or piece of clay and when they are shaken they make a noise. Their true purpose is unclear, but various theories suggest that they may have been suspended from a dancer's belt or were a representation of a bull's scrotum and used in fertility rites. We shall probably never know.
