Kändler's Taxa records the model as 'A Harlequin with his hat making a very deep bow. 2 Thalers.', and Ingelore Menzhausen has suggested that the inspiration for this grussender Harlequin model is the engraving of the Expulsion of the Italian Comedians in 1697 after a lost painting of Watteau. Meredith Chilton, in Harlequin Unmasked, Singapore, 2001, pp. 124-126, discusses this specific bowing pose, which appears to reflect a movement performed by the Commedia dell'Arte actors. She also illustrates the example in the Gardiner Museum, Toronto, fig. 199, and quotes Pierre Rameau's description of the pose in his 1714 publication Maître à danser:
'In regard to the passing bow, this is done in the same manner as the bow forwards, save the body must be turned diagonally towards the persons you salute. That is, you turn half-sideways towards them, sliding forwards the foot that is nearest them, whether it be the right or the left, bending at the waist and inclining the head at the same time...'
