Meyerbeer took particular care over the first London and Berlin productions. He travelled to London to check the singers and production for the original version, and requested that the German translation for Berlin be undertaken by the poet Ludwig Rellstab, strongly recommending that Taglioni and her father Fillipo be re-engaged, and that Ciceri's sets should be reproduced. Although Taglioni danced and the sets were retained, the translation was eventually carried out by Meyerbeer's friend Theodor Hell. Meyerbeer wrote additional ballet music for Taglioni for the Berlin production.
