Blake's myth surrounding Urizen is found in many of his works, and can trace back to his experiments in writing myths about a god of reason in the 1780s, including in "To Winter".
Blakeov mit o Urizenu nalazi se u mnogim njegovim djelima te se njegov izvor može pronaći u njegovim eksperimentima u pisanju mitova o bogu razuma iz 1780-ih, uključujući i u radu "Prema zimi".
