The filler font is Virgula Vulgaris Bold, a personal serif font, just to complement the initials. This is not mandatory, any font will be secondary, anyway. The initials from A to Z will support any Latin language that will not start with an accented letter. It’s hard to imagine how could anyone fit a diacritic among the leaves.
Technicalities
For anyone interested, in the paragraph above the first letter is separated with a short PHP code, so the HTML is generated automatically, something like this:
$text = get_the_content_html(); // the text
$initial = trim( $text[0] ); // get the first letter
$rest = substr( $text, 1 ); // exclude the first letter
Then all the elements are placed back, where the <i> tag is the initial, styled in CSS:
echo ‘<p><i>’ . $initial . ‘</i>’ . $rest . ‘</p>’;
This can be useful if the initials are needed for paragraphs, using another font than the default. In case the font is used in digital texts, at least, and the initials won’t end up in someone’s bathroom, as tile decorations.
Credits

“William Morris (24 March 1834 – 3 October 1896) was a British textile designer, poet, artist, fantasy writer, architectural conservationist, printer, translator and socialist activist associated with the British Arts and Crafts Movement. He was a major contributor to the revival of traditional British textile arts and methods of production. His literary contributions helped to establish the modern fantasy genre, while he helped win acceptance of socialism in fin de siècle Great Britain …
… Morris is recognised as one of the most significant cultural figures of Victorian Britain. He was best known in his lifetime as a poet, although he posthumously became better known for his designs. The William Morris Society founded in 1955 is devoted to his legacy, while multiple biographies and studies of his work have been published. Many of the buildings associated with his life are open to visitors, much of his work can be found in art galleries and museums, and his designs are still in production.”
