From The Greatness of Saturn by Robert Svoboda

Lord Saturn is tall, black, long-limbed, and emaciated, with reddish-brown eyes, large teeth and nails, prominent veins, a sunken stomach, a long beard, matted locks, and profuse coarse, stiff body hair. He is lame and his limbs are rigid; his constitution is Vata. Intensely harsh, he is cruel in authority, and his gaze, which is directed downward, is utterly terrifying. He is a Shudra; some even call him outcaste. By trade, he is an oil-presser who worships Kali Bhairava (the great Black Terrifier). His metal is iron and his gem is blue sapphire.

Lord of the sinews and nerves, of the west, of Saturday, and of the constellations Capricorn and Aquarius, he is also known as the Slow, Son of Shadow, the Angular, the Black, the Endless, the End-Causer, the All-Devouring, the Steady, the Controller;, the Famished and the Emaciated.

If you hope to prevent Saturn from mangling your life, as he has mangled so many lives, make regular offerings of black sesame seeds, sesame oil, and sugar on Saturdays to an iron image of that planet; also, make Saturday donations of sesame and iron to the needy.
