Rara avis - The Guardian (20/09/2013)

In a poem composed to celebrate the victory, Knox dedicated one stanza to Mavis: "When Cunningham won at Matapan, By the grace of God and Mavis, Nigro simillima cygno est, praise Heaven, A very rara avis." ("Like the black swan, she is, praise heaven, a very rare bird".) It was, she later said, "very heady stuff for a 19-year-old"
