Antyllus is a Greek surgeon who lives in the 2nd century CE in Rome.

He is most notable for his method of treatment of aneurysms.

He describes the types of aneurysms, and creates a taxonomy related to the lesions' potential for rupture.

He lives in the same era as Galen, and as Galen is the dominant figure in the field of medicine, Antyllus excels in surgery.

His works have been lost, though some are reflected in the writings of Oribasius.

He develops specific instructions for a number of operations.

He also lists the indications and contraindications and describes the complications that can arise from the operations.

His operation for aneurysm remained the standard procedure until the 19th century.

ntyllus is also said to have developed a procedure to extract cataracts from the eye via suction, as claimed by Muhammad ibn Zakariya al-Razi in the 10th century.
