To make something artistic or to treat something with artistic concern; to refine or enhance something artistically (rare and archaic).
From art plus -ize (suffix meaning 'to make' or 'to cause to be'). A formation similar to modernize or standardize, but extremely rare in actual usage.
The -ize suffix is so productive that people can create new verbs on the fly—'to Zoom,' 'to Google,' 'to artize'—even if most of these invented verbs disappear and never make it into dictionaries.
