George Leo Haydock, on Jdt 1:1

“Now Arphaxad king of the Medes had brought many nations under his dominions, and he built a very strong city, which he called Ecbatana,”

“Now, refers to the internal purpose of the author. (St. Gregory, hom 2. in Ezechiel.) (Worthington) Many of the books begin with And; shewing their connection. This work formed a part of the general history. The building of Ecbatana likewise took place soon after the destruction of Ninive, mentioned in the preceding book. — Arphaxad. He was probably the same as is called Dejoces by Herodotus; to whom he attributes the building of Ecbatana, the capital city of Media; (Challoner) or rather Arphaxad, more resembles both in name and actions the second king Phraortes or Apharaartas, (Montfaucon and Houbigant) who fortified and embellished the city. (Calmet) — Ecbatana, or Agbata, which in Arabic signifies “variegated;” (Bochart) as the seven walls, rising one higher than another round it, were marked with one white, two black, three red, four blue, five dark red, six silver, seven gold. (Herodotus i. 98.) (Calmet) See Tobias iii. 7.”
