Lorca's supposed giving up of poetry

 "After 1930, Federico García Lorca moved almost entirely from poetry to theater so as to engage audiences directly... "

I think the "almost" is doing a lot of work there. Since Lorca only lived until the middle of 1936, we have barely a half decade, with three major poetic works: Llanto por ISM, the sonnets, and the Diván. Then the six Galician poems (maybe a minor work), and some uncollected poems. It is true that the balance shifts from the 20s, when Lorca wrote Cante jondo, Canciones, Suites, Poeta en Nueva York. 

Also, Lorca remained interested in his "impossible" theater to the end. It is not true that he simply wanted to "engage audiences."
