The play premiered at the Comédie-Française on Thursday 29 August 1748. It was performed 68 times by Lekain between 1756 and 1778.

The MS is a composite manuscript, with numerous hands contributing to its construction. It is part of a broader collection of MSS relating to the theatre that was bound in 1871. This copy appears to have been revised after a reading of BNF, Français 24347, f.1-38, another contemporary copy of this play that was owned by La Vallière.

The MS was originally catalogued with the shelfmark: Supplément français 5246.

The title page carries, in the upper left corner, Wagnière’s endorsement ‘bon original’. This manuscript represents an intermediary stage, positioned between TP01 and K84. It incorporates a considerable number of the variants of TP01, whilst removing a few other variants. Among other drafts, it has the denouement found in K84. The manuscript contains minor variants as well.

Voltaire acknowledged the receipt of a manuscript from Lacombe on 29 May 1775. The similarity with MS1 might also suggest a connection with the Marquis d’Argenson’s copy.

The same copyist and the same corrector were responsible for MS2 of Adélaïde Du Guesclin and for MS1 of Les frères ennemis.
