It's interesting how both pics leave the Middle East and find the 'Temple of the Oracle' and 'The All-Seeing Eye' in some mythical place that's clearly a lost spin-off from Hindu India. And both Sinbad and Abu have to battle the negative feminine, in one case Kali, and in the other the Giant Spider and Octopus in the goddess's temple. Each film if you're into symbolism is an alchemist's dream.
Rozsa did use some authentic raga themes: in fact Kali's fight music is such, if I recall correctly, as is the Jungle theme in Jungle Book. And there's a wonderfully Indian passage when Abu enters the temple.
But Sinbad is a little more (marginally) 'Arabic' than Thief, because the latter leans to Rimsky-Korsakoff more than Sinbad.
