In its primitive days of being written, Mycenaean Greek was written applying a syllabary. Nonetheless, for nearly 2700 years, Greek has been written adopting an alphabet. As with alternative writing systems, over time, distinctive writing styles developed. Comparable to how modern English has many deviations from constant to script writing and capital to lowercase letters, Ancient Greek had disparate written alterations as well.

Three important changes were the initial Greek alphabet (uppercase), the sign script and the Greek microscopic script (lowercase).

This is the simplest of the alphabets to grasp. The most familiar place to use letters was to engrave them into gravestones. To aid the carving procedure, the letters turned to have few curves. They were also consistently sized comparable to what we call “uppercase” letters today. In reality, many of them are used as dominant letters in the Latinic inscribing system that English is written in.

Here is an illustration of the early Greek historic script:

Α, Β, Γ, Δ, Ε, Ζ, Η, Θ, Ι, Κ, Λ, Μ, Ν, Ξ, Ο, Π, Ρ, Σ, Τ, Υ, Φ, Χ, Ψ, Ω

The initial alphabet was typed without any spaces or punctuation. The trouble of differentiating among words and sentences would decline on the reader. A big example of this type of writing can be found on the Rosetta Stone.

Greek Microscopic Writing

Someplace in the past two thousand years, Greek letters became smaller. A writing technique known as minuscule (similar to lowercase letters) matured. Some works were handwritten completely in minuscule. Others were a combination of the previous uppercase (majuscule) and minuscule scripts. Where the two writing styles arise simultaneously, the minuscule was constantly more widespread. Just as with English, exact nouns and the first word of a section would be capitalized. Nevertheless, in ancient Greek, the first word of every single sentence was not written with capital letters (except if it was a proper noun or the starting point of a paragraph as noticed above).

You can see the alphabet in microscopic script below: 

α, β, γ, δ, ε, ζ, η, θ, ι, κ, λ, μ, ν, ξ, ο, π, ρ, σ, τ, υ, φ, χ, ψ, ω

Just as the monumental script has remained as the majuscule letters of Modern Greek, the minuscule script prevails as the lowercase letters of Modern Greek. A graduate of Modern Greek would grasp both the majuscule and minuscule writings in order to be able to study and write the language.
