Soon,
August Pezold and Hippius's old friend Otto Ignatius, who had left the
St. Petersburg Academy, met up and hoped to meet Hippius in Berlin. The journey of these three artists from what is now
Estonia has been partially but quite detailed preserved in travel writings, based on which Leopold von Pezold, August Pezold's son, wrote an article in the journal
Baltische Monatsschrift in 1890. According to Leopold, the artists intended to publish their travel writings with drawings, but this task was carried out decades later by Leopold. The travel writings represent pages from Hippius's and Ignatius's diaries. Hippius's autobiographical section reflected the period from June 1816 to May 1818. On September 16, 1816, Hippius left Vienna with painter to travel on foot. (which is now at the
Beethoven House in
Bonn), and
Thorvaldsen. Overbeck, in turn, painted his portrait. In his diary, Hippius wrote that his life's aspirations were reflected in his meetings with four outstanding people of his time – Beethoven, Overbeck, Thorvaldsen, and
Pestalozzi – representing music, painting, other arts, and pedagogy. Hippius was the first of the three friends to leave Italy. In the second half of 1818, he spent about a year in
Switzerland, where he visited Pestalozzi in
Yverdon and painted his portrait. Along with his portraits of Beethoven and Thorvaldsen, he valued this portrait more than all his other works and published it as a
lithograph in 1846 to mark the great educator's centenary. == Later years ==
