Philo: On the Life of Moses, II

XXI. (101) And in the space between the five pillars and the four pillars, is that space which is, properly speaking, the space before the temple, being cut off by two curtains of woven work, the inner one of which is called the veil, and the outer one is called the covering: and the remaining three vessels, of those which I have enumerated, were placed as follows:--The altar of incense was placed in the middle, between earth and water, as a symbol of gratitude, which it was fitting should be offered up, on account of the things that had been done for the Hebrews on both these elements, for these elements have had the central situation of the world allotted to them.

And from this candlestick there proceeded six branches, three on each side, projecting from the candlestick in the centre, so as altogether to complete the number of seven; (103) and in all the seven there were seven candles and seven lights, being symbols of those seven stars which are called planets by those men who are versed in natural philosophy; for the sun, like the candlestick, being placed in the middle of the other six, in the fourth rank, gives light to the three planets which are above him, and to those of equal number which are below him, adapting to circumstances the musical and truly divine instrument.
