AD LIT: How to use an Astrolabe; Treatise on the Astrolabe, Geoffroy Chaucer

 Why you might read The Treatise on the Astrolabe?

This Treatise is the first description of a scientific instrument or technical manual in English. As such it is an interesting read. Chaucer did not finish it. In his introduction, he details five sections but we only have the first two. In my Self Education project, it rounds out Chaucer's work. As well as being an interesting romp into an obscure scientific instrument of the 1400s.


Synopsis of The Treatise on the Astrolabe

 The Treatise is a letter to a young Lewis. This may or may not be Chaucer's son. The introduction indicates five sections but we only have the first two. These cover a in-depth description of the instrument itself. The translation I used had a diagram of the description which helped with visualisation. The second section is instructions on its use in normal situations. As well as a series of variations.  

Reflections on The Treatise on the Astrolabe

Not having an Astrolabe to look at and interact with made this text rather challenging. Of course, it being in middle English didn't help either. That being said it was still an interesting read.

It was interesting to look at some of the older ideas around horoscopes. Today we only see horoscopes online or in magazines. And they have their own language and term. In this treatise, we see how those terms came to be and what is meant by having a planet in retrograde or a planet being in a sign.


What others have to say about The Treatise on the Astrolabe

"His Treatise on the astrolabe was written during the 1390s. It is the first 'technical manual' of its kind to be written in English instead of Latin, Greek, or Arabic." From St Johns College

Comparisons with other texts

This isn't the first technical document in my Self Education project. We have seen works by Hippocrates which are all factual pieces. For example On Surgery gives a detailed description of how to bandage patients. By contrast, this treatise is on a single instrument and how to manipulate it.

This is very different from Chaucer's other original work. Well semi-original as it is said to be based on two other works, but it is not a translation. His other original work is almost entirely in verse. By contrast, this treatise is entirely in prose. The Canterbury Tales is more about telling stories. Whereas this treatise is entirely factual. It also has a specific recipient in mind rather than the broad audience of the Tales.

Conclusion

This is a tricky work to get your head around. But it is a clear description of the instrument called the Astrolabe and its working. While it is not as well known as the Canterbury tales it shows a different side of Chaucer. In all, it gives some background to modern-day horoscopes.

The Life Of Cyrus; Cyropaedia, Xenophon

Why you might read Cyropaedia?

This short history details the life of Cyrus. It is told by Xenophon who does not overlap time-wise with Cyrus. It is a great look into the rise of the Persian Empire. It includes commentary about how Cyrus achieved it all. As well as how he made it harmonious at least for his lifetime. All in all, it is an easy-to-read little history of the Persians. In my Self Education project, it stands as a history of one of the great civilisations. 

Synopsis of Cyropaedia

Book I:

Xenophon gives the details of Cyrus' upbringing. This includes the time he spent with his grandfather with the Medes. It is here he learns horsemanship. The tail of the section is spent with a dialogue between Cyrus and his father. In this, they discuss what a commander of men really needs to know. It is far more than the tactics Cyrus has been formally taught. You must have the men feed and trust you to command an efficient force.  

Book II:

This book looks at how Cyrus set up and trained the army that Persia sent to Medea. It explains the contests that were set up to motivate the men to train. Xenophon also spends some time telling stories of how Cyrus gave honour to the men. These rank from the lowest soldier to the highest captains. It finishes with an account of the dialogue with the masses. And how Cyrus got them to agree that they should be rewarded based on their accomplishments. This is in contrast to the status quo of all the soldiers being rewarded equally.

Book III:

Here we follow Cyrus raising an army to help defend his grandfather's kingdom. Xenophon details how he trained and maintained the army. We follow the army to his grandfather's territory. Before they set out for the enemy Cyrus detours to get troops from a reluctant ally. While doing this he also manages to gain an extra ally. When they finally meet the enemy they charge with such ferocity that the enemy runs. 

Book IV:

We see Cyrus take the army to chase the enemy. His grandfather does not want to but says he can take any of the Medes who will follow him. Cyrus convinces most of them. During the pursuit, one of the enemy's allies defects to Cyrus' forces and leads on as a guide. The enemy again flees and the Cavalry pursues. Cyrus decides that the Persians need their own cavalry. They will take the enemy horses that were left behind and learn. Cyrus takes so many prisoners and booty that he sends them to Persia for re-enforcements. About this time his grandfather realizes he has been left all but alone at the camp. He sends an angry message for the Medes to return. Cyrus sends a reply message that they have won the day which he hopes will calm his grandfather. 

Book V:

Cyrus' army takes on the Assyrians in battle and the king is killed. The Assyrians retreat and the son is elevated to king. Immediately a delegation comes to Cyrus offering to come to his side as the new king killed this lord's son. After a few more days another lord who the king had made into a eunuch also defects to Cyrus' side. Cyruses grandfather throws another wobbly upon coming to the front. He worries that he is being outdone by the honour guard that comes to greet him. Cyrus eventually pacifies him but not until he has given the older man back his pride. 

Book VI:

Cyrus regroups. He puts to the troops the question of continuing the campaign. They all agree with his assessment that they need to press forward. Cyrus sends multiple spies to the Assyrian side at varying levels of importance. They all come back with the same report. The enemy is massing troops and securing outside help from the Egyptians. Cyrus constructs new chariots with scythes on the wheels to run through infantry. Cyrus marches the army onward until they see the dust of the enemy. They form up in battle array and get ready to fight. 

Book VII:

Cyrus takes the army against the enemy and wins a resounding victory. He then takes one wealthy city and comes away with a lot of plunder and a city under his control. He then persuades the generals to continue the campaign. They then besiege Babylon. They take Babylon by re-directing the river that flows through the city. They used the dry bed to enter the city. Cyrus then sets himself up as king. But he explores the Persians who are with him to continue their lives of virtue. As well as training their sons in the same way as at home. 

Book VIII:

Xenophon describes how Cyrus sets up the running of his empire. The empire went well for Cyrus and he became known by the people as father. He does so by continuing the tradition of hardship for the nobles. He also continues as he did as a general and is lavish with gifts to recognize honourable men. Xenophon continues with an account of Cyrus knowing he will die and giving his last words of wisdom to his sons. But Xenophon does not stop there. He gives a brief account of the abandonment of Cyruses virtues in modern Persia.

Reflections on Cyropaedia

Cyropaedia is a concise little history. It might have overly rose-coloured glasses in its portrayal of Cyrus. There is no doubt, however, that he did great things and established an empire.

Xenophon's focus on the generosity and graciousness of Cyrus is interesting. He paints Cyrus as a saint of virtue and a firm believer in the providence of keeping your men happy. He is at all times at pains to show honour where honour is due. As well as making sure the army is fed and paid. At times he seems to focus too much on this but it always works well in his favour
I found Cyrus' adoption of the Median dress once he secures the Empire quite odd. He and his men are proud Persians and he emplores them to stay as such in their virtues. It seems counter to the rest of what he has done to give them a style of dress that is not Persian and also extravagant. 

What others have to say about Cyropaedia

 
"CYROPAEDIA, a partly fictional biography of Cyrus the Great (559-29 b.c.e.), founder of the Achaemenid empire" From Encyclopaedia Iranica

"Instead, it was meant to instruct its readers, primarily the Greek elites, in matters of both politics and morality. Nonetheless, the Cyropaedia still offers a fascinating look at the life of Cyrus the Great." From The Collector

Comparisons with other texts

Cyropaedia in some ways continues the themes of On The Cavalry Commander. On The Cavalry Commander is entirely about how to organise and train troops. Cyropaedia by contrast has it mixed through an account of someone doing exactly. Though that is on a  much larger scale. Cyrus organises and trains his troops with a similar ethos. This leaves me to wonder how much Xenophon took his theory from accounts of Cyrus.

Xenophon ends with a description of how Cyrus set up his Kingdom. This is very different to the details given in The Constitution of the Lacedemonians. It seems the greatness of a state or empire is not attached to its system of government.

Conclusion

This is a nice Pseudohistory even if it was written as more of a moral text. It covers the life of Cyrus right from childhood and training. It continues all the way to Kingship, dying and instructing his sons. It gives an interesting insight into how the Greeks saw the Persian Empire. This is in spite of their conflicts.

UPDATE: A New Year and new priorities


So it's 2024. When did that happen? I hope the year has treated you all well. And the New Year has sparked me to rethink this project.

In short, I'm done.

Not with the reading list but with this blog. I love the reading but the writing has become a huge drag for me and I don't have so much time now that we have a wee son. So thank you for coming along for this part of the journey. I have two more posts written that will both post this month  (Today and Monday the 8th) then that is it. 
I wish you all well in your own self-education.
