"In the name of God the Merciful. (May) the blessing of God be on our lord Mohammed and his kin; health and peace. (This lamp) was ordered (to be made) by our Lord the egregious sultan, the favoured, the victorious, the just, the happy, the conqueror of cities, and the extreme boundary of just conduct among the servants (of God); the emir of the Mussulmans Abu-Abdillah, son of our lord the emir of the Mussulmans Abu-Abdillah, son of our lord Al-Galib-Billah, the conqueror through God's protection, the emir of the Mussulmans Abu-Abdillah; (may) God aid him (praised be God)." Here is a breakage and a corresponding gap in the inscription, which continues, "beneath it, lighted by my light for its magnificence and the care of its _xeque_, with righteous purpose and unerring certainty. And this was in the month of Rabié the first blessed, in the year 705.[91] May (God) be praised." [91] September 20th to October 19th, A.D. 1305. The history of this lamp has been explored with scholarly care by Rodrigo Amador de los Ríos, whose monograph will be found in the _Museo Español de Antigüedades_. He says that the lamp was formerly suspended from the ceiling of the chapel of San Ildefonso in the university of Alcalá de Henares. Here, too, he has discovered entries which relate to it in two separate inventories, dated 1526 and 1531, from which we gather that the lamp, excepting the lowest part or tier, which probably proceeded from Oran, was brought to Alcalá by Cardinal Cisneros from the mosque of the Alhambra of Granada. [Illustration: XXXIII MOORISH LAMP AND MORTAR (_Museum of Granada_)] All of the lamp (continues Amador) that properly belongs to it, is the open-work shade, together with the graduated set of spheres which we now observe on top.[92] The lowest part is clearly an inverted bell, from which project four decorative pieces. This is believed by Amador to be a Spanish bell, dating from the fifteenth century, designed for striking with a hammer, and proceeding from some monastery or convent plundered by the Moors. Indeed, one of the two inventories discovered at Alcalá mentions "a bell with a hole in it, _which used to belong to a Moorish lamp_," thus countenancing the widespread supposition that the lamps of the mosque of Cordova were made of the Christian bells of Compostela, which the fierce Almanzor caused to be conveyed upon the aching backs of Christian captives to the Moorish court and capital of Andalusia.
