In Medieval Europe (476A.D. to 1453A.D.), a T/O map represented a Flat Earth concept of the world. The T/O map divided the world up into three parts:
The Divine Comedy was a three-part epic poem written by Dante Alighieri from 1308 and up until his death in1321. It is a first-person account of his descent into Hell (in the Inferno), his passage up the mountain of Purgatory (in the Purgatorio), and his final ascent into Heaven (in the Paradiso). Although it is concidered to be an allegory, much of his storyline aligns with the beliefs of a majority of Medieval Europeans as to how the universe was stuctured. It is a Ptolemaic universe and Dante draws upon ancient Greek and Roman mythology (see Gods & Monsters of Ancient Greece) with great liberality while he gives an account of the Christian concept of God.
If you are curious as to how well you would fair against Dante's ideals, you can take the following test:

Analysis of Biblical text by medieval scholars led them to the conclusion that if man was made in God's image, then human proportions may hold a divine code. The inch, foot, cubit, and many geometric forms found in the human body were a reflection of God and the inner workings of the universe. Whether as a symbolic gesture or not, the church represented the body of god, the masons and architects of this period applied human proportions to the floorplans of basillicas and cathedrals.
Such belief in the significance of an underlying numerical code to reality, inspired extensive studies and research into the nature of human existance and the universe to which we are bound. The mystical views of Numerology, Astrology, Alchemy and the Cabalah are still prevalent in our popular culture today through belief in lucky or unlucky numbers, astrological readings, and magical charms. Although the validity of the medieval mysticism and the devine nature of humanity remain in question, it was these early concepts that became the foundations of our current scientific disciplines in Mathematics, Astronomy, Chemistry, and Physics.
