What were the Original Methods of Meditation and their Instructions as Expounded by the Buddha?

In Theravada, I know there is union in understanding that the Buddha taught two types of meditation: vipassana (insight) meditation and samatha (tranquility) meditation. However, I have come across various types of these meditation methods over the years, either with an emphasis on samatha meditation, vipassana meditation, or both, all filled with various interpretations. My question is the following: **Putting aside the modern methods of meditation taught by members of the later Sangha and their interpretations as well as going back to the Buddha and his early Sangha, what was it that the Buddha originally taught in regard to meditation (samatha and vipassana meditations) and what instructions did the Buddha give as to how one practices them?** *PLEASE REFERENCE THE TIPITAKA OR SOURCES STRICTLY USING THE TIPITAKA.* -Apannaka
