Alexander had designed the harbor using the exact same blueprint as the famous harbor of Carthage.
And as Diaogosis was interpreting the drawings, Alexander leaned forward and offered, "Here, let me explain,"
"The center crescent will be used to house military ships. It will be 300 m in diameter and be surrounded on all sides by 10ft walls. Its entrance will be guarded using chained gates that can be raised or lowered and this is where we will build our new ships."
He then moved his fingers to the horizontal strips and said, "And these two strips of the harbor will be where the regular, civilian ships will dock. They will be an artificial construct extending half a kilometer into the sea and will be able to hold more than a 100 ships at a time."
Alexander sounded very proud of his design as he then asked Diaogosis, "So if I give you the 2,000 slaves I bought, how long do you think it will take you to build?"
"..." Diaogosis somewhat regretted asking to see the design.
