Leucothoé is a 1756 dramatic poem by the Irish playwright Isaac Bickerstaff.
Leucothoé was originally intended to be a pastoral opera but Bickerstaff was unable to secure a composer to set it to music.
[1] In a contemporary review in the Monthly Review, critic Ralph Griffiths generally praised the work, although he criticised the tragic ending, as "the laws of the Opera require a happy ending".
This failure led Bickerstaff to rejoin the military, although he went on to have a string of successes between 1760 and 1772 often in collaboration with the composer Thomas Arne.
