Schiaparelli? Wasn't my first guess. Lowell was.

No, but from the same period as Schiaparelli - even the same opposition as the famous one that resulted in canali and satellites, I think.

WAG based on a half-memory: Herschel?

You Doofus! No... He was 100 years before the opposition I just mentioned.

Hi Phil:

I think this might be Dawes' work.

If I recall correctly, he was an English astronomer in the mid-19th century, and he named all the continents and seas he observed on Mars. Places like "Dawes' Continent", and "Dawes' Ocean"...

Hmm. Flammarion? Looks similar, but different.

Simon is close... but Dawes was the observer, not the cartographer.

Proctor, then? I wouldn't have guessed that.

Excellent - now we have the cartographer, Richard Proctor. All we need now for the unveiling of the great Mars Bar is the publication. Who can track that down?

Proctor was criticised quite correctly for naming too many things after Dawes - including Dawes' Forked Bay, which was Schiaparelli's Sinus Meridiani. So he revised his naming scheme. And look at the map... where Schiaparelli had 'canali', he has rivers!

Did these guys know how large Mars was? Would have been some wide rivers.

Okay, an attempt at redemption: Proctor's Other Worlds Than Ours, 1870.

No, the 'Other Worlds' map was his first, the one with the flawed nomenclature.

"Did these guys know how large Mars was? Would have been some wide rivers. "
Not really - lines are not usually drawn with width to scale - look at the width of a highway on a road map of a continent.

Yeah. And I'm not saying they didn't lack the skepticism to consider that linear features could be lots of other things. It's just that when you look at a globe of the earth, and imagine it through a telescope, you won't see rivers. It would have been interesting to wonder what they expected Earth's albedo features to be. Were they expecting Amazon and Nile or even Red Sea in amongst water, brown land, green land, ice, and clouds?

Might actually be interesting to get a few photos of Mars at opposition through similar or antique telescopes and say, this is about what they were looking at. Granted, the eyeball is a little better than a photo.
