Similar to MacLise's renaming of the days in the earlier 'Year' , 'The Universal Solar Calendar' renames the days of the year, but in this format prints the phrases in his characteristic calligraphic hand, producing a full artwork that actually seems to take itself a bit more seriously than most of the multiples produced by Macianus at the time.
