In the preface to the Carus Verlag edition of Haydn's 'Insanae et vanae curae' (2009), Armin Kircher suggests that 'for the revival in the Burgtheater, Vienna in March 1784, Haydn modernized his oratorio 'Il ritorno di Tobia'. He added the choruses 'Ah, gran Dio' and 'Svanisce in un momento', the second of which, called 'Der Sturm', was reworked in[to] the sacred motet 'Insanae et vanae curae (Hob. XXI:1/13c).'
