Rudolf II, Holy Roman Emperor
Möller was born in Königsberg. He began at 15 years old (22 April 1578), a seven-year apprenticeship in Prague at the court of Rudolf II, Holy Roman Emperor. During this time he frequently copied works by Albrecht Dürer. Reviewing stylistic changes in his works, it is presumed he traveled in 1585 to 1587 Italy (especially Venice), and on his return spent some time in the Low Countries (especially Antwerp and Amsterdam) as well.
