Final answer:
William Blake was a renowned artist and engraver who became more famous for his visual arts during his life than poetry. His body of work encompasses both, but it is as a visionary poet that he is widely celebrated today. The correct answer is A.
Step-by-step explanation:
The artist and engraver who made his living primarily in these professions, rather than as a poet until his death, was William Blake. William Blake was intensely creative, producing a vast body of work that included not just poetry but also significant contributions to visual arts.
Both during and after his lifetime, Blake was best known for his engravings and mythologically and spiritually rich paintings. His visionary style distinguished him from his contemporaries, yet it is as a poet that many recognize him today, especially for his works such as 'Songs of Innocence and of Experience' and 'The Marriage of Heaven and Hell'.
Though he did not gain widespread acclaim during his lifetime, his influence on the arts and poetry has since been acknowledged and celebrated. The correct answer is A.
