Der Himmel dacht auf Anhalts Ruhm und Glück, BWV 66a
(Since heaven cared for Anhalt's fame and bliss), BWV66.1, BWV66a, is a congratulatory cantata by Johann Sebastian Bach. The work was first performed in Köthen on 10 December 1718.

History 
Bach composed the secular cantata, or serenata, in 1718 in Köthen to celebrate the twenty-fourth birthday of his employer Leopold, Prince of Anhalt-Köthen on 10 December. The cantata text was by Christian Friedrich Hunold, who was based at Halle. Bach and Hunold collaborated on other cantatas, including one for the same birthday, .

Hunold's text was included in a collection,  (Selected and partly never printed poems), which he published the following year, and has thus survived. Bach's music has been lost apart from a fragment, but there is scope for its reconstruction as he recycled some of it in at least one sacred work.

Bach adapted several movements for his 1724 cantata for Easter Monday, . While the structure of the sacred cantata is different (it is closed with a chorale, and it opens with music from the closing movement of the secular cantata), Bach preserved the original dialogue form in which two allegorical figures appear. For  (Fortune of Anhalt) and  (Fame), he substituted the alto "Fear" in place of Fortune and the tenor "Hope" in place of Fame.

John Eliot Gardiner has suggested that instrumental music from the lost cantata survives in another cantata from the composer's Leipzig years. The music in question, a sinfonia for strings and woodwind, is the first movement of , which was first performed in 1725.
