The Book of DieselThe Light Before the Gospel“They could not save everything. Atar chose the workers' tablet from Behistun and lost Roxana's complete book of royal women. Anahita saved Shirin's marginal copy of Esther and left three generations of family letters to burn. Preservation was another form of grief because every rescued object accused the hand that abandoned another.”
