I thought it was a fun idea to ask the reader about the painting. I also wanted to end this story with the end of the day.
For those of you new to Latin, pingit, pinxit and picta are all forms of the same verb. pignit - he or she paints, pinxit - he or she (has) painted, picta - painted. If you were to look the word up in a dictionary your would see: pingo, pingere, pinxi, pictum (verb) to paint. This is the detail you need to form this verb in its myriad of mutations. The noun pictor, too, is formed from pictum and means 'person who paints'.
Marcellus has now painted for many hours. Does the painting, painted by Marcellus, please you? Night is now here and Marcellus is tired.
