Serapeum
A serapeum is a temple or other religious institution dedicated to the syncretic Hellenistic-Egyptian god Serapis, who combined aspects of Osiris and Apis in a humanized form that was accepted by the Ptolemaic Greeks of Alexandria. There were several such religious centers, each of which was a serapeion (Greek: Σεραπεῖον) or, in its Latinized form, a serapeum.

Serapeum, quod licet minuatur exilitate verborum, atriis tamen columnariis amplissimis et spirantibus signorum figmentis et reliqua operum multitudine ita est exornatum, ut post Capitolium, quo se venerabilis Roma in aeternum attollit, nihil orbis terrarum ambitiosius cernat.
The Serapeum, splendid to a point that words would only diminish its beauty, has such spacious rooms flanked by columns, filled with such life-like statues and a multitude of other works of such art, that nothing, except the Capitolium, which attests to Rome's venerable eternity, can be considered as ambitious in the whole world.
