This is a pictograph of a wooden staircase viewed in profile. The spaces between the newels and the spindles depict three steps. The steps descend from right to left. This symbol is a mirror image of the symbol for upstairs. It is therefore an ideograph for the adverb downstairs.

Indus inscription M-1680 is read from right to left. I have therefore assumed that the direction of travel on the staircase is from right to left.
