- among numerous closely spaced aids for a railing
- a little line or pilaster, used as a support to your train of an available parapet, to protect the side of a staircase, or perhaps the front side of a gallery. See Balustrade.
"help for a railing," c.1600, from French balustre, from Italian balaustro "pillar," from balausta "flower of the crazy pomegranate," from Greek balaustion (possibly of Semitic beginning; compare Aramaic balatz "flower of this crazy pomegranate"). Staircase uprights had lyre-like dual curves, like the calyx pipe of this pomegranate flower.
High; the network baluster round the top is modern.
