#EIRENE ( #Irene) was the #goddess of #peace and the season of #spring.

She was one of the three Horai (Horae), deities of the seasons and keepers of the gates of heaven. Her sisters were Eunomia (Good Order) and Dike (Justice).

Eirene's name is the Greek word for peace (eirênê) but it is also closely connected with the word for spring (eiar, eiarinos). In #ancient #Greece late spring was the traditional campaign season, the time when peace was most at risk.

Eirene was probably identified with the Hora Thallo (Green Shoots), whose name Hesiod uses as an epithet for Eirene in the Theogony. Her opposite number was Polemos (War).

In classical art the goddess usually appears in the company of her two sister Horai bearing the fruits of the seasons. Statues of the goddess often depict her as a maiden holding the infant Ploutos (Plutus) (Wealth) in her arms. In this guise she was identified with the Demeter and Tykhe (Tyche), the goddesses of agricultural bounty.

After lunch yesterday, we went to the #HistoryOfScienceMuseum in #Oxford. It's not very big but contains some really fascinating exhibits. It is right next to the #SheldonianTheatre and well worth a visit.

Here are wooden models of the #FivePlatonicSolids.

This is a beautiful example of #HandWriting in a book. #Writing like this is certainly a lost art these days.

Here I am explaining to my spouse the similarities and differences between #Octants, #Sextants and #Quadrants.

This wooden box contains some immaculate #brass #DrawingInstruments. Another rarity these days but I do remember learning how to use similar #instruments while studying at university.

Without anything but manual #SurveyingEquipment, humans were able accurately to map out the entire globe. It's amazing what can be achieved when humanity works together. But also, this model is absolutely gorgeous.

Not to be outdone, the #astronomers mapped the #sky and here it appears on a companion globe.

No computers were around then but the ingenuity of humans to develop calculating instruments to allow them to crunch numbers meant the creation of some devices of stupendous cunning.

To this day, trainee pilots have to master the #CircularSlideRule in order to do calculations for various tasks. Before flying was ever developed, such #SlideRules were in common use.

This #camera is another fine example of hand-made instruments. The craft and skill of whoever made it is a marvel.

Yesterday, we went on a day trip to #Oxford by #train. No other means of powered transport was used as we #cycled to and from our local #RailwayStation.

Here is the #countryside zooming past the train window.

It was a nice day to be out and the city has its own distinctive #architecture, much dominated by the UniversityOfOxford.

Some of the centre is a zero-emission zone or #ZEZ, aimed at curbing the use of polluting vehicles. Such vehicle owners need to pay to use roads in that area.

Here I am walking up a street with some nice buildings in the background.

The #SheldonianTheatre. This is where the degree ceremonies take place.

Oxford #TownHall is in a similar style to other buildings in the city.

I'm not sure what this building is but I don't think it's part of the university.
