Philo Judaeus De Plantatione 4

[4] For how can it be looked upon as anything but a prodigy, for that which would dissolve another thing, to be held together by that which it would dissolve: that is to say, for water to be held together by earth; and again, for that which is the hottest of all things to be placed upon that which is the coldest without its nature being destroyed, that is to say, for fire to be placed upon air? And these are the elements of this most perfect plant; but the very great and all productive plant is this world, of which the aforesaid branches are the main shoots.
