from some, of the ancient monuments of these masters 
of the world. The arcades of the parallelogram leading 
to the court j T ard of the church, which have been closed 
in modern times, strengthens my opinion. The 
mosques in Morocco have them open as on the other 
three sides of the court-yard; and so they formerly were 
in the church of Cordova. Hence it is incontestable, 
that this temple was originally a mosque, built by the 
Moors, and not an edifice of the Romans, as some 
Spanish writers pretend. 
The caroubin, like all monuments of this kind, is not 
adorned with any paintings; the floor is covered with 
mats, a general custom in all religious buildings of this 
nature. The attendants of the place have three indiffer- 
ent clocks in the minaret, by which they regulate the 
hours for prayer. On the terrace are two small hori- 
zontal sun-dials to mark the time of noon; at my arri- 
val they were in such an incorrect position, that they 
differed by four or five minutes from the true time; ob- 
serving this, I drew a line to fix the true east direction, 
and had the satisfaction to hear the hour of noon an- 
nounced at the exact moment. 
The minaret contains also a terrestrial globe; an ar- 
millary sphere, and a celestial globe; they were all made in 
Europe abo*t an hundred years ago; and as the Ma- 
hometans do r^t know how to use them, they are aban- 
doned to the dus\ damp, and the rats; hence it is im- 
possible, I will not say, to read them, but even to de- 
cypher the letters or \o see the figures. In another 
room there is a collection of old books which have 
shared the same fate. I made manv exertions to dis- 
cover the complete works of the famous Titus Livius, 
which are supposed to have been in this library; but all 
my researches were fruitless. I saw nothing like them
