In December of that year, Tycho invited Kepler to visit him in Prague; on January 1, 1600 (before he even received the invitation), Kepler set off in the hopes that Tycho's patronage could solve his philosophical problems as well as his social and financial ones.
1. jaanuaril 1600 (ta ei olnud siis veel Brahe kutset kätte saanud) hakkas Kepler lootma, et Tycho eestkoste lahendab nii tema filosoofilised kui ka sotsiaal- ja finantsprobleemid.
