The “Doodles” of Greek Mathematicians: Scribe’s Notebooks Reveal How They Calculated in Roman Egypt



A new war of words has broken out between Egypt and Ethiopia over the Grand Ethiopian Renaissance Dam (GERD). It comes as renewed fighting in northern Ethiopia pulls the country’s long-running disputes with its neighbors back into the open.
Ethiopia’s government has blamed neighboring states for the escalating conflict in the north. The government has accused Eritrea, Sudan, and Egypt of backing armed opposition groups, raising fears that the conflict could expand regionally. Birhanu Jula, Ethiopia’s army chief, stated that the Tigray People’s Liberation Front has clearly needed outside support and supplies from Egypt, Sudan, and other foreign powers to sustain its campaign.
Cairo rejected the claim. Foreign Ministry spokesman Nader Zaki said Egypt’s foreign policy rests on respect for the sovereignty, unity and territorial integrity of other states and on staying out of their internal affairs, adding that claims to the contrary had no basis in fact.
The dispute quickly returned to the Nile. On Saturday, Ethiopia’s minister of Water and Energy, Habtamu Itefa, published a social media post, later deleted, comparing the GERD to Egypt’s Aswan High Dam. “Before criticizing Ethiopia, Egypt should explain why it built the Aswan High Dam without Ethiopian consent.”
Cairo responded the same day. A source at the Egyptian Ministry of Water Resources and Irrigation called the post “shameful” and said it reflected political confusion.
“Responding to such nonsense and the political confusion reflected in the post would be nothing more than a waste of time,” the source said. The source called the post “a desperate attempt to divert attention from the core dispute: Ethiopia’s continued unilateral actions over its illegal dam, which violate international law.”
Habtamu made the same argument. He said it was shameful to hear Egyptian politicians demand that Ethiopia obtain their consent for dams that do no significant harm, and argued that Egypt had not consulted Ethiopia when it built Aswan. He described Cairo’s insistence on prior consent as an outdated approach rooted in colonial-era arrangements.
The $5 billion GERD sits on the Blue Nile, about 14 kilometers from the Sudanese border. It is 1.8 kilometers wide and 145 meters tall, with a design capacity of 5,150 megawatts. Prime Minister Abiy Ahmed inaugurated it on September 9, 2025. Egypt and Sudan, the downstream states, have long demanded a legally binding agreement on how it is filled and operated. The United States has also stepped back, in a January 2026 letter to President Abdel Fattah el-Sisi, US President Donald Trump offered to restart US-led mediation between Egypt and Ethiopia on Nile water-sharing.
The leaders of Egypt, Sudan, Eritrea, and Somalia met in El Alamein and issued a joint declaration covering both the Red Sea and the Nile, and among other things. On the question of the Red Sea, the four states affirmed “the principle of freedom of navigation and that the governance of the Red Sea is the exclusive responsibility of the littoral states.”
Regarding the Nile, the declaration emphasized “the importance of respecting international law regarding transboundary rivers including the Nile River particularly the principle of ‘no harm’ and the obligation to cooperate through prior notification, consultation, and consensus.” It also categorically rejected “any unilateral measures that harm the existing water uses of the two downstream Nile states.” The four countries pledged to keep strengthening “consultation and coordination among the four countries and other sisterly African nations.”
Ethiopia issued its own statement in response to the El Alamein declaration, arguing, “Ethiopia is the source of the Abay River, commonly known as the Blue Nile. Virtually all of the Blue Nile originates in the Ethiopian highlands, and the Abay contributes about 85% of the Nile River’s total flow. Any discussion concerning the utilization and management of the Abay River should be informed by these fundamental realities.”
Insisting that, “Despite changes in political boundaries over time, Ethiopia remains closely connected to the Red Sea, with its nearest border lying barely 30 miles from the coast. Accordingly, any serious discussion of regional maritime affairs and security architecture must account for Ethiopia’s legitimate interests and its enduring connection to the Red Sea.”
It added, “These geographic and historical realities cannot be altered by political rhetoric, coercive measures, or acts of destabilization. Actions taken through proxies or acts of aggression will not change the facts on the ground, nor will they diminish Ethiopia’s legitimate interests, role, and responsibilities in the region.”
Reaffirming that it “stands ready to defend its sovereignty, territorial integrity, and core national interests,” Ethiopia urged regional actors to pursue “constructive dialogue, partnership, and adherence to the principles of good neighborliness rather than confrontation and zero-sum approaches.”
With fighting is spreading in Ethiopia’s north and rival blocs are forming along the Red Sea, the Nile dispute could be tied into a wider regional confrontation.








Chinese President Xi Jinping underlined the need for stronger international coordination for common security in West Asia and a reaffirmation of the UN Charter and international law.
Xi demanded external powers must respect sovereignty and territorial integrity of the countries in the region and stop interfering in their internal affairs.
China is ready to work with the countries in the region to “safeguard the security of international shipping lanes, advance development cooperation, promote the convergence of interests of regional countries, gradually enhance mutual trust, and eliminate root causes of the conflict,” Xi proposed.
Xi made the statement during his two day state visit to Egypt on Wednesday, September 2. This was his first state visit to the country in 10 years.
Xi’s visit coincided with the 70th anniversary of establishment of bilateral relations between the two countries and took on greater significance in the context of ongoing wars in Palestine, Lebanon, and Iran.
Xi and Egyptian President Abdel Fattah El-Sisi signed a joint declaration which recognized Palestine as the core issue in the region and underlined the importance of “reaching a just and lasting settlement based on the two-state solution” and creation of an “independent and sovereign” Palestinian state as per 1967 borders and with East Jerusalem as the capital.
Both the countries also rejected “any plans to displace the Palestinian people from their lands under any pretexts or names” and called for a true ceasefire in Gaza with unrestricted flow of humanitarian aid.
Israel has killed hundreds of Palestinians in Gaza since the ceasefire was announced last year in daily attacks. It has also prevented the flow of humanitarian aid to the region and expanded the war against Palestinians by launching attacks in other occupied territories such as the West Bank and East Jerusalem.
Xi presented a four-point proposal for enhancing common security in West Asia, which will keep the external forces out and achieve lasting stability and peace in the region.
Guo Jiakun, official spokesperson of China’s Ministry of Foreign Affairs, explained Xi’s four points during a regular press conference on Thursday.
As per Xi’s proposal, increasing dialogue among the countries in the region is the first necessary step in achieving common security. This step must be followed by building comprehensive regional governance of hotspot issues.
Third, Xi claimed, increased possibilities of mutual development would pave the way towards lasting stability and security in the region.
Identifying that lasting peace and stability in the region is “fundamentally dependent on development” Xi also offered Chinese help to the countries in the region in achieving the same.
This regional set up, as the last step, needs international backing by institutions such as the UN for sustenance. The support of the countries in the region to the UN will in turn make it “play a tangible role in regional affairs” as well.
The China-Egypt joint declaration talks about their efforts to amplify the voice of the Global South by “supporting the right of the developing countries to fair and balanced participation in international economic and political decision making.”
Egypt recently joined BRICS, a 11-member group working for a multipolar world and democratization of the global governing institutions including the UN and international financial institutions.
It also participated in the recently concluded Shanghai Cooperation Organization (SCO) summit in Bishkek as a Dialogue Partner. The summit adopted a joint declaration talking about the democratization of the global governance mechanisms.
Apart from BRICS and the SCO, Egypt and China are also part of the China-Arab States Cooperation Forum and Forum on China-Africa Cooperation. All these organizations have the stated goals of working against unilateralism and acts of bullying in international politics.
Their joint declaration also talked about strengthening political and security coordination on regional and international issues of common interest which may include conflicts in the region.
China is one of Egypt’s largest trading partner with their bilateral trade reaching $20 billion last year.
As a part of the larger agenda of the countries in the Global South to reduce their dependence on the US dollar, both the countries signed an agreement to pay for all their bilateral trade in their local currencies.
