Archimedes
Archimedes of Syracuse ( ; ) was an Ancient Greek mathematician, physicist, engineer, astronomer, and inventor from the city of Syracuse in Sicily. Although few details of his life are known, based on his surviving work, he is considered one of the leading scientists in classical antiquity, and one of the greatest mathematicians of all time. Archimedes anticipated modern calculus and analysis by applying the concept of the infinitesimals and the method of exhaustion to derive and rigorously prove many geometrical theorems, including the area of a circle, the surface area and volume of a sphere

Syracusia

Syracusia (, syrakousía, literally "of Syracuse") was an ancient Greek ship sometimes claimed to be the largest transport ship of antiquity. She was reportedly too big for any port in Sicily, and thus only sailed once from Syracuse in Sicily to Alexandria in the Ptolemaic Kingdom of Egypt, whereupon she was given as a present to Ptolemy III Euergetes. The exact dimension of Syracusia is unknown; Historian Michael Lahanas put it at long, 14 m wide, and 13 m high.

Pseudo-Archimedes
Pseudo-Archimedes is a name given to pseudo-anonymous authors writing under the name of 'Archimedes' as quoted by various sources of the Islamic Golden Age such as Al-Jazari for the construction of water clocks. Archimedes himself is not known to have written any such manuscript as almost all the manuscripts have been lost.
