XLVI. (226) This other point also is too important to deserve to be passed over in silence: that, as there are three vessels among the sacred furniture, a candlestick, a bath, and an altar of incense; the altar of incense has reference to that gratitude which is exhibited for the bestowal of the elements, as has been shown before, since it does itself also receive a portion from these four, receiving wood from the earth, and the species which are burnt from the water; for, being first of all liquefied, they are dissolved into drops of moisture, and vapour from the air, and form the fire the spark which kindles the whole; and the composition of frankincense, and galbanum, and onycha, and stacte, is a symbol of the four elements; and the table is referred to the gratitude which is displayed for the mortal things which are made out of the elements, for loaves and libations are placed upon it, which the creatures who stand in need of nourishment must of necessity use. And the candlestick has reference to the gratitude exhibited for all the things existing in heaven, in order than no portion of the world may lie under the imputation of ingratitude; but that we may see that every single part of it gives thanks, the elements, the things made of them, and not those only which are made on earth, but also those in heaven.
