Born and raised in the Duchy of Urbino . He studied medicine at Padua ( 1534 ) and Ferrara ( 1544 ) universities; having received a doctorate in medicine, he returned to Urbino in 1546 and was about to engage in medical practice, but became a teacher of mathematics at the court of the Duke.

Liber de centro gravitatis solidorum , 1565

Translated into Latin directly from the original Greek such classical works as:

• treatises of Archimedes “Measurement of a circle”, “On spiral lines”, “Quadrature of a parabola”, “On conoids and spheroids”, “Psammit” ( 1558 ), “On bodies floating in water” ( 1565 );
• The Konik Apollonius ( 1566 );
• The "Beginnings" of Euclid ( 1572 );
• Heron's “Pneumatics” ( 1575 , published posthumously);
• Pappa's “Mathematical Collection” ( 1588 , published posthumously).

From the original works of Kommandino known "Description of the clock" ( 1562 ) and "On the center of gravity of solids" ( 1565 ).

Having studied the heritage of Archimedes , Commando in his scientific works relied on the methods and ideas of the ancient Greek scholar. In particular, he extended to the spatial case the theorem proved by Archimedes that the three medians of a triangle intersect at one point and are divided by this point into two parts with respect to 2: 1, counting from the top; as a result of this distribution, the Commando theorem (1565) was included in the courses of stereometry .

Commandando's theorem : Four segments connecting each vertex of a tetrahedron with the intersection point of medians of the opposite face intersect at one point dividing each of these segments in a 3: 1 ratio (counting from the vertex) ^[1] .

Among the students of Federico Commandando are Guidobaldo del Monte and Bernardino Baldi .
