What is "tiriel"

Tiriel is the eponymous character in a poem by William Blake written c.1789, and considered the first of his prophetic books. The character of Tiriel is often interpreted as a foreshadowing of Urizen, representative of conventionality and conformity, and one of the major characters in Blake's as yet unrealised mythological system.

Tiriel is a narrative poem by William Blake, written c.1789. Considered the first of his prophetic books, it is also the first poem in which Blake used free septenaries, which he would go on to use in much of his later verse. Tiriel was unpublished during Blake's lifetime and remained so until 1874, when it appeared in William Michael Rossetti's Poetical Works of William Blake. Although Blake did not engrave the poem, he did make twelve sepia drawings to accompany the rough and unfinished manuscript, although three of them are considered lost as they have not been traced since 1863.

Tiriel, Op. 41, (Russian: Тириэль) is a 1985 opera by the Russian composer Dmitri Smirnov in three acts (9 scenes) with a symphonic prologue to his own English libretto after a poem of the same title by William Blake. It has been translated into Russian and German.
