Smyth strikes again

Interesting tidbit I picked up today from Smyth:

966. The verb may agree with the nearest or most important of two or more subjects. The verb may be placed

a. Before both subjects: ““ἧκε μὲν ὁ Θερσαγόρα_ς καὶ ὁ Ἐξήκεστος εἰς Λέσβον καὶ ᾤκουν ἐκεῖ” Thersagoras and Execestus came to Lesbos and settled there” D. 23.143.

b. After the first subject: ““ὅ τε Πολέμαρχος ἧκε καὶ Ἀδείμαντος καὶ Νικήρατος καὶ ἄλλοι τινές” Polemarchus came and Adimantus and Niceratus and certain others” P. R. 327b, ““Φαλῖνος ᾤχετο καὶ οἱ σὺν αὐτῷ” Phalinus and his companions departed” X. A. 2.2.1.

c. After both subjects: ““τὸ βουλευτήριον καὶ ὁ δῆμος παρορᾶται” the senate and the people are disregarded” Aes. 3.250. (Cp. Shakesp. “my mistress and her sister stays.”）
