Quote:Thanks Michael, yes indeed there is a resemblance
i doubt Maraldi was watching the same side of mars, too bad we'll never know what he saw (or is there software able to go back a few centuries ).
to me it looks a bit like one of Huyghens' sketches of Syrtis Major, take a look at his right sketch here. perhaps maraldi failed to see Syrtis Major extending further north, or there was haze obscuring it, or perhaps that feature was not as dark as it is now...
i find those old planet sketches fascinating!
i looked the book you mentioned up on amazon.com, "perhaps i'll buy it", i thought. seems they're selling from $50 up to $663
