Ihr Häuser des Himmels, ihr scheinenden Lichter, BWV 193a

Ihr Häuser des Himmels, ihr scheinenden Lichter (Ye houses of heaven, ye radiant lights), BWV 193.1 (formerly BWV 193a), is a secular cantata by Johann Sebastian Bach first performed on 3 August 1727. The music is lost, but it can be partially reconstructed as several movements (including the opening chorus) are known to have shared music with Ihr Tore zu Zion, BWV 193.2, a church cantata which was premiered around three weeks after Ihr Häuser des Himmels, ihr scheinenden Lichter.
