PLATE 3. A marginal T-O map appears in a
thirteenth-century manuscript of the Etymologies
of Isidore of Seville. An obscure text around it
seems to describe the movement of “Kasepium”
(perhaps the constellation Cassiopeia), through
the east and north, to the west and south. Thanks
to Elisa Ruiz (UCM) and Ignasi Baiges Jardí (UB)
for their help reading the Latin text. By Permission

John’s University (Collegeville, Minn.), Steiner
