Passage 8.16.4
τάφους δὲ ἀξίους θαύματος ἐπιστάμενος πολλοὺς δυοῖν ἐξ αὐτῶν ἐπιμνησθήσομαι, τοῦ τε ἐν Ἁλικαρνασσῷ καὶ ἐν τῇ Ἑβραίων. ὁ μὲν δὴ ἐν Ἁλικαρνασσῷ Μαυσώλῳ βασιλεύσαντι Ἁλικαρνασσέων πεποίηται, μέγεθος δὲ οὕτω δή τί ἐστι μέγας καὶ ἐς κατασκευὴν περίβλεπτος τὴν πᾶσαν, ὥστε καὶ Ῥωμαῖοι μεγάλως δή τι αὐτὸν θαυμάζοντες τὰ παρὰ σφίσιν ἐπιφανῆ μνήματα Μαυσώλεια ὀνομάζουσιν·
Though I know of many tombs worthy of admiration, I shall mention two among them, namely the one in Halicarnassus and that in the land of the Hebrews. The one at Halicarnassus was built for Mausolus, who was king of the Halicarnassians, and it is so extraordinary in size and remarkable in craftsmanship that even the Romans, greatly admiring it, call their own splendid tombs "mausolea."
