They believed that a genius was this, sort of magical divine entity, who was believed to literally live in the walls of an artist's studio, kind of like Dobby the house elf, and who would come out and sort of invisibly assist the artist with their work and would shape the outcome of that work.
Vjerovali su da je genij neko magično božansko biće koje doslovno živi u zidovima umjetnikovog studija, poput kućnog vilenjaka, koje izlazi van, nevidljivo pomaže umjetniku pri poslu i tako oblikuje krajnji ishod djela.
