From the very beginning of her career Mueller amazed one by her striking artistic
personality, the original material with an excessive and exaggerated quality about
it. She was tall with a trim figure and elongated proportions. She did indeed
possess a powerful, high and forceful leap, a broad extension and a passionate,
even fiery temperament, in addition to the overwhelming desire to stun, excite and
thrill. This was most probably an unconscious desire - a person with such
expressive exterior and rich physical potential must use them, spend them, realise
them.
Her art might please or displease, her treatment of parts might be considered
insufficiently profound, superficial, even incorrect, but the lavishness of her
performance was infectious and charming, riveting the eye, and quite enthralling.
The ballerina's movements, dictated by genuine emotion, infected spectators by
their rhythm carrying them away, and they always experienced that spiritual
excitement which always heralds an encounter with something genuine and real.
Occasionally there even seemed to be something fantastic about Mueller, for
example, when the colour of her hair in the Bacchante suddenly recalled legends
of red-headed temptresses who caused bloody internecine battles when,
captivated by the shining stream of golden locks, son rose against father, and
brother against brother.
