change the word "Pages" to a different word with

Hi everyone, I’m trying to add some php to a sidebar menu so that it shows the children of the page it is on, one step in – I’ve gotten this far, but when it shows up, it has the title “Pages” – I want to change the title to “Artwork” – anyone have any ideas?

<?php
// Globalize the $post variable;
// probably already available in this context, but just in case…
global $post;
wp_list_pages( array(
// Only pages that are children of the current page
‘child_of’ => $post->ID,
// Only show one level of hierarchy
‘depth’ => 1
));
?>
