William Tyler Olcott,
A Field Book of the Stars — Ophiuchus and Serpens
(1911)
“ Ophiuchus is represented as an old man, holding in his hands a writhing serpent. Ras Algethi, the head of Hercules, lies just west of Ras Alhague. Equally distant southeast and southwest of Ras Alhague, are to be seen two stars close together, representing the shoulders of Ophiuchus. His foot rests on the Scorpion just above Antares. ”
