To list all authors from your blog in WordPress, you can use the wp_list_authors() function. This function displays a list of all the users who have published posts on your WordPress site.

Here is an example of how to use the wp_list_authors() function in a WordPress template file:

<ul>
  <?php wp_list_authors(); ?>
</ul>

In this example, the wp_list_authors() function is used inside a <ul> element to create an unordered list of all the authors on the WordPress site. The list will display the authors’ names and links to their author archives.

You can also use the wp_list_authors() function with various arguments to customize the output of the list. For example, you can use the orderby and order arguments to control the sorting of the authors, and the number argument to limit the number of authors displayed in the list.

Here is an example of using the wp_list_authors() function with arguments:

<ul>
  <?php
  wp_list_authors(array(
    'orderby' => 'display_name',
    'order' => 'ASC',
    'number' => 10
  ));
  ?>
</ul>

In this example, the wp_list_authors() function is used with the orderby, order, and number arguments. The orderby argument specifies that the authors should be sorted by their display names, the order argument specifies that the authors should be sorted in ascending order, and the number argument specifies that only the first 10 authors should be displayed in the list.

I hope this helps! Let me know if you have any questions.
