Back in London in 1733, Veracini appeared in many concerts. In 1735 he composed an opera for the Opera of the Nobility, "Adriano in Siria". Francesca Cuzzoni, Antonio Montagnana, Farinelli and Senesino had a role. George Frederic Handel was present at the premiere in Haymarket Theatre. Charles Jennens liked the opera and ordered a score; Lord Hervey, not known for his musical perception, and Henry Liddell, 1st Baron Ravensworth were bored. However, the work enjoyed a run of twenty performances over six months. Many of the arias were published separately by John Walsh . Veracini composed the fifth version, based on Pietro Metastasio’s libretto, written for the Habsburg Emperor Charles VI. The score, which survived in the Newman Flower Collection (or the Henry Watson Music Library?) of the Manchester Central Library was developed by German musicologist Holger Schmitt-Hallenberg along with Fabio Biondi, who composed the recitatives that have not been preserved. It was performed in Kraków December 2013 and in Vienna and Madrid in January 2014.
