Sandalphon (Hebrew: סַנְדַּלְפוֹן Sandalp̄ōn; Σανδαλφών Sandalfón) is an archangel in Jewish and Christian writings, although not in scripture. Sandalphon figures prominently in the mystical literary traditions of Rabbinic Judaism and early Christianity, notably in the Midrash, Talmud, and Kabbalah and is generally seen as gathering prayers and passing them on to God. Though not explicitly referenced in scripture, some of the earliest sources on Sandalphon refer to him as the prophet Elijah transfigured and risen to angelic status. Other sources (mainly from the midrashic period) describe him as the "twin brother" of Metatron, whose human origin as Enoch is similar to the human origin of Sandalphon. The name Sandalphon, which may be related to the Hebrew sandek, godfather (thereby corresponding to the tradition of a station held by Elijah with regard to evocation of the prophet in his capacity being protector of unborn children), may also be derived from the Greek prefix sym-/syn-, meaning "together", and adelphos, meaning "brother"; thus approximately meaning "co-brother", since the modern Greek word for "co-worker", synadelfos (συνάδελφος), has these roots as seen in the Book of Revelation, chapter 19, verse 10. This probably refers to Sandalphon's relationship to Metatron, though this derivation shows uncertain Semitic influences. Physical descriptions of Sandalphon vary depending on the source. He is uniformly depicted as extremely tall—he exceeds Hadraniel in height by a 500-year foot journey. During Moses' visit to the Third Heaven, he is said to have glimpsed Sandalphon and called him the "tall angel", though this legend dates to much later than the time of the Torah. The Babylonian Talmud Hagigah 13b says Sandalphon's head reaches Heaven, which is also said of Israfil and of the Greek monster Typhon, with whom Sandalphon seems to have similar mythological roots. He is also described as being a member of the śārim (שָׂרִים "princes"), and a Hazzan (חַזָּן master of heavenly song).
