Goodricke and Constantine without honor in their own city

Today I went on a free guided tour of York, provided by one of the many volunteers who have been providing this service since 1950 (!). Well worth the time and I'm grateful to the organization and our guide.

However, I must say that he had me biting my tounge more than once with his version of York history (and of his weakness for terrible folk etymologies no more will be said). My faith in his knowledge of his home town's history -- and he called himself a local historian -- was given a shock when he called Athelstan a Viking king. I mean, is there a more (Old) English name? If, dear reader, you were a volunteer guide at York, I believe you would not make this mistake.

Nor, I hope, would you try to be relevant by saying that Henry VIII used the loot from the Dissolution of the Monasteries "to found the Oxbridge Consortium." Would you?

It's odd what people include, and don't. Maybe there was no archaeological or architectural hook to bring in the Pilgrimage of Grace, but I bet I could find one. (Just sitting here I now have one.) But how can you say that the late Roman HQ was found under the Minster in the late 1960s, and not mention that Constantine was elevated to the emperorship in York? This has got to be one of the most important things, on a world-historical scale, to ever happen in the city. But it went unmentioned.

And about the same time Constantine was being ignored, we were standing in front of the Treasurer's House in the old ecclesiastical enclave, also ignoring a sign that said John Goodricke worked there in the 1780s on Cepheid variables, the discovery of which eventually provided an astronomical yardstick to estimate the size of the universe. Talk about world-historical.

I should study up and volunteer myself...

Challenge: look up Henrietta Swan Leavitt, who should have got a Nobel Prize. No York connection.

Nicholas of Cusa and Ethan Allen, cosmic speculators

Dr. Beachcombing is impressed with the fact that Nicholas of Cusa,15th century canon lawyer, astronomer, and philosopher, put his intellect to work on the question of the size and habitability of the universe:

Nor can place furnish an argument for the earth’s baseness. Life, as it exists here on earth in the form of men, animals and plants, is to be found, let us suppose, in a higher form in the solar and stellar regions. Rather than think that so many stars and parts of the heavens are uninhabited and that this earth of ours alone is peopled — and that with beings, perhaps, of an inferior type — we will suppose that in every region there are inhabitants, differing in nature by rank and all owing their origin to God, who is the centre and circumference of all stellar regions. Now, even if inhabitants of another kind should exist in the other stars, it seems inconceivable that, in the line of nature, anything more noble and perfect could be found than the intellectual nature that exists here on this earth and its region. The fact is that man has no longing for any other nature but desires only to be perfect in his own.

Me, I rather prefer the superficially similar but perhaps more generous speculations of Ethan Allen, founder of Vermont and in that cause a rebel against both the British Empire and the United States of America:

Furthermore, it is altogether reasonable to conclude that the heavenly bodies, alias worlds, which move or are situate within the circle of our knowledge, as well all others throughout immensity, are each and every one of them possessed or inhabited by some intelligent agents or other. however different their sensations or manners of receiving or communicating their ideas may be from ours, or however different from each other. For why would it not have been as wise or as consistent with the perfections which we adore in God, to have neglected giving being to intelligence in this world as in those other worlds, interspersed with another of various qualities in his immense creation? And inasmuch as this world is thus replenished, we may, with the highest rational certainty infer, that as God has given us to rejoice, and adore him for our being, he has acted consistent with his goodness, in the display of his providence throughout the university of worlds.
To suppose that God Almighty has confined his goodness to this world, to the exclusion of all others, is much similar to the idle fancies of some individuals in this world, that they, and those of their communion or faith, are the favorites of heaven exclusively; but these are narrow and bigoted conceptions, which are degrading to a rational nature, and utterly unworthy of God, of whom we should form the most exalted ideas.
