Start with primary texts, but do not stop at plot summary: pair each text with criticism, translation comparison or a course resource so the reading becomes analytical. Keep the question comparative: how does a form, image, voice or myth travel between ancient and later writing? The Odyssey gives a modern route into epic, homecoming, voice and reception. The Aeneid is useful for Roman epic, empire, imitation and literary inheritance. Metamorphoses is the obvious next step for myth, transformation and later English reception. Greek Tragedy gives a manageable route into tragic form, conflict, rhetoric and performance.
For critical method, use structured resources rather than collecting quotes. Introduction to Theory of Literature introduces major questions about what literature is and how interpretation works. Great Writers Inspire offers Oxford-created literary resources, talks and contextual material for advanced school readers. Getting started on classical Latin is a free starting point for students considering beginners' Latin. Classical Association Resources provides a curated bank of classical topics, language materials and teaching resources.
Podcasts can work well if you listen actively and keep notes on claims you would challenge. Approaching Shakespeare models close reading and critical questioning of Shakespeare. In Our Time gives expert conversations across literature, history, philosophy and classical topics. A History of the World in 100 Objects helps connect ancient texts with objects, empire, exchange and interpretation; for Classics and English, use it to ask how material culture changes the literary reading, not just to collect background facts. Literature and History gives chronological world-literature episodes with ancient Greek and Roman context.
