Spyders & symmetry.

"Tyger ! Tyger ! burning bright in the forests of the night, what immortal hand or eye could frame thy fearful symmetry ? in what distant deeps or sloes burnt the fire of thine eyes ? on what wings dare he aspire ? what the hand dare sieze the fire ? and what shoulder & what art, could twist the sinews of thy heart ? and when thy heart began to beat, what dread hand ? & what dread feet ? what the hammer ? what the chain ? in what furnace was thy brain ? what the anvil ? what dread grasp dare its deadly terrors clasp ? when the stars threw down their spears, and water'd heaven with their tears, did he smile his work to see ? did he who made the Lamb make thee ? Tyger ! Tyger ! burning bright in the forests of the night, what immortal hand or eye, dare frame thy fearful symmetry ? "
William Blake.
