Saint Isidore of Seville (c. 560 – April 4, 636) was Archbishop of Seville for more than three decades and has the reputation of being one of the great scholars of the early Middle Ages. All the later medieval history-writing of Hispania were based on his histories.

Isidore taught in the Etymologiae that the Earth was round. His meaning was ambiguous and some writers think he referred to a disc-shaped Earth; his other writings make it clear, however, that he considered the Earth to be globular. Isidore's disc-shaped analogy continued to be used through the Middle Ages by authors clearly favouring a spherical Earth, e.g. the 9th century bishop Rabanus Maurus who compared the habitable part of the northern hemisphere (Aristotle's northern temperate clime) with a wheel, imagined as a slice of the whole sphere.
