long and adventurous, setting out from Naples in July 1810 and not arriving in the Piraeus until September. At Athens, they were joined by the British architects and archaeologists John Foster and Charles Robert Cockerell. The group carried out excavations at several Greek sites – in 1811 at the Temple of Aphaia at Aegina, they removed the fallen fragmentary pediment sculptures and on von Hallerstein's recommendation shipped them abroad and sold them the following year to Crown Prince Ludwig of Bavaria; and in 1812 they exposed parts of the temple of Apollo at Bassae (the frieze they found on it is now in the British Museum) and Aeacus's temple of Zeus Panhellenios (Panhellenic Zeus), again at Aegina. Rome and Italy In autumn 1814, Stackelberg returned from Greece to his family in the Baltic States. He travelled to Italy again in 1816, researching antiquity and the Middle Ages as an art historian and becoming co-founder of the "Instituto Archeologico Germanico" in Rome. Together with Eduard Gerhard, August Kestner and Theodor Panofka, he also established in 1824 the "Hyperboreans" ("Römischen Hyperboraeer") there, a group of northern European scholars who studied classical ruins. Both were the precursors and embryonic stages of the later German Archaeological Institute. In 1826 Stackelberg's archaeological work was published as Der Apollotempel zu Bassae in Arcadien und die daselbst ausgegrabenen Bildwerke (The Temple of Apollo at Bassae in Arcadia, and the Wall-paintings excavated there), for which he also provided the drawings. Also during this time in Rome in the middle of his life, Stackelberg undertook further trips to Greece, to Turkey and within Italy. In Etruria in 1827 he discovered the Etruscan temple and hypogaeum at Corneto (now Tarquinia). Later life and death In 1828 Stackelberg left Rome and Italy for the last time. From 1829 to 1833 he lived once again in Germany, meeting there among others Johann Wolfgang von Goethe and travelling to England, France and the Netherlands. From 1835 he lived in Riga. Reception His daughter Natalie von Stackelberg published a biography of him in 1882 on the basis of her father's journals and letters. In his biography of von Stackelberg, Gerhart Rodenwaldt called him the "discoverer of the [ancient] Greek landscape".
