The older portion, the capella in palatio, an octagonal building surmounted by a dome, was designed on the model of San Vitale at Ravenna by Udo of Metz, was begun under Charlemagne's auspices in 796 and consecrated by Pope Leo III.
It is also suggested that the capella was simply the tent or canopy which the French kings erected over the altar in the field for the worship of the soldiers.
Its form is peculiar, and is an imitation of a similar work by Marcianus Capella, De Nuptiis Philologiae et Mercurii.
There is only one railway in the state, which runs from Aracaju northward to Capella, with a branch running westward to Simao Dias.
Neckam also wrote Corrogationes Promethei, a scriptural commentary prefaced by a treatise on grammatical criticism; a translation of Aesop into Latin elegiacs (six fables from this version, as given in a Paris MS., are printed in Robert's Fables inedites); commentaries, still unprinted, on portions of Aristotle, Martianus Capella and Ovid's Metamorphoses, and other works.
