Origins of poetry

My heart takes root in her and grips with its nail,
holds on like bark on the rod,
to me she is joy’s tower and palace and chamber,
and I do not love brother as much, or father, or uncle;
and there’ll be double joy in Paradise for my soul,
if a man is blessed for loving well there, and enters.

– Arnaut Daniel, 12^th century
