* Illuminated printing: Blake's most famous works were illuminated books, which combined hand-written text with elaborate illustrations. He created these books using a unique process called "relief etching," where he would engrave the text and illustrations on a single plate and then print them together. He used a variety of mediums for the illustrations, including watercolor, ink, and gouache.
* Poetry: Blake was also a gifted poet and wrote numerous poems, many of which accompanied his illustrations.
* Watercolors and Drawings: Blake produced many individual watercolors and drawings, often on themes of mythology, religion, and the human condition.
In addition to these, he also created:
* Engravings: Blake produced a number of engravings for other artists and publishers, including works for Dante's *Inferno* and John Milton's *Paradise Lost*.
* Designs for books: He designed illustrations for other books, such as the Bible and *The Book of Job*.
It's important to note that Blake was not just an artist but also a visionary thinker and poet. His art was deeply infused with his own philosophical and religious beliefs, which often expressed themes of social justice, spiritual enlightenment, and the power of imagination.
