Members of Iran's tiny Jewish minority gathered at the holy shrine of the Prophet Daniel in the southwest of the country Thursday to celebrate their Persian roots and keep alive a dwindling community.

More than 200 Iranian Jews embarked on the long journey to Susa from cities across Iran to celebrate their Jewishness in an event organized by a local Jewish youth group to support the community.

"Prophet Daniel is the symbol of our proud Persian roots. The gathering in Susa is to highlight our presence in Iran since ancient times," said Farhad Aframian, the editor of the monthly Jewish magazine, who described the gathering as an opportunity for Jews from all over the country to socialize and keep in touch.

In addition to the tomb of the Prophet Daniel, Iran is also home to another of Judaism's important sites, the shrine of Mordechai an Esther, who became a Persian queen and persuaded King Xerxes not to slaughter the Jews in an event subsequently celebrated by the festival of Purim

As usual with this sort of thing, any direct connection between these monuments and the figures they honor is to be taken with a grain of salt.
