Mickiewicz’s pensive face is shown in profile. The painter subtly depicted a staring eye, a clear eyebrow arch, dark strands of hair, and sideburns growing on the cheeks. From the surviving accounts we know that contemporaries paid attention to the well-captured likeness. Mickiewicz and Wańkowicz’s acquaintances from their studies in Vilnius, members of the Filaret Society, were in St Petersburg at the time: Stanisław Morawski and Mikołaj Malinowski. ‘In this portrait, the artist managed to poetise, idealise, and beautify the face of our bard, and yet make him look most like him,’ Morawski admired in his memoirs.
Malinowski, however, wrote in a letter to the historian Joachim Lelewel:
Mickiewicz’s arrival in St Petersburg caused an unprecedented sensation. Russians and Poles alike compete in showing him respect. […] Mickiewicz has changed from the outside, he has grown sideburns, which makes him more serious. His complexion is healthier, he has grown slightly more robust, he has changed, but to his own advantage. In company, he is not as eccentric as before; instead he is very free and engaging.
Wańkowicz was regarded by his friends as a very conscientious person. Work on the portrait must have been progressing well, as in May 1828, the painting was shown at an exhibition at St Petersburg’s Academy of Fine Arts. The work was very popular, not only thanks to the painter’s talent, but also due to Mickiewicz’s fame. It was not simply a likeness of the writer, but an image of the great Romantic, harmonising with the writer’s own works. 'Wańkowicz penetrated the poet’s spirit', claimed the artist’s colleague, painter Wincenty Smokowski, noting that he captured not only 'the likeness of the face', but also 'the touching poetry'.
The painting soon became the most recognisable – and widespread – image of Mickiewicz. Already in June 1828 Wańkowicz created a lithograph based on it. The graphic reproduction was reproduced en masse, significantly contributing to the popularity of the original. Soon the artist also made several smaller replicas of the painting.
