Ben Bulben is a large flat-topped rock formation in
County Sligo, Ireland. It is famous in
Irish legend, appearing in
The Pursuit of Diarmuid and Gráinne, and was the site of a military confrontation during the
Irish Civil War. The phrase "Mareotic Lake", which appears in the second line of the poem, is used in the classical religious work
De Vita Contemplativa to refer to
Lake Mariout in Egypt which was the location of the
Therapeutae, a community of religious hermits.
Phidias, mentioned in part IV of the poem, was one of the most influential sculptors in classical Athens. The
Parthenon Frieze was probably sculpted under his direction. ==Yeats's gravestone==
