Cosmic Cycles

This cosmic order, which came into existence in the far distant past, is not eternal but must eventually perish. Its destruction will come in a tremendous conflagration, called the ekpyrosis, in which everything will be changed into fire (J. van Arnim Stoicorum Veterum Veterum Fragmenta Leipzig 1903-05 inc. by M. Adler, Leipzig 1924:1.107,510-12,2.585-620)
Then after a period during which nothing but fire exists, the world order will again come into existance, and by the very same process as that which brought the present world into existence (1.109, 512, 2.593,596,597,599,620,622-32)
