"Johann Jakob Walther (23 January 1604 – 1676/7 Strasbourg) was a painter and natural history illustrator, who chronicled the life of Strasbourg during the Thirty Years' War, but is best known for his work Horti Itzeinensis aka the Nassau Florilegium depicting flowering plants from the gardens of Johann, Count of Nassau-Idstein at Idstein.
Walther was the son of Gerard Walther. He probably trained in the workshop of miniaturist Friedrich Brentel. He left Strasbourg around 1618 and returned in 1635. He was elected to the Grand Council of the city in 1659. His meeting in Strasbourg with the Count was a decisive moment in his career, since the Count became one of his most important patrons.
