"Promiscuity" is the seventh song of Samuel Barber's song cycle Hermit Songs. The cycle was composed in 1953 and published in 1954. The premiere was sung by soprano Leontyne Price.
The poem is a translation of a text by an anonymous Irish monk who lived sometime between the 8th and 13th centuries. The English translation used by Barber is by Kenneth Jackson.
I do not know with whom Edan will sleep,
but I do know that fair Edan will not sleep alone.
